XML DOM wrapper (COM)

weaponx · November 9, 2008

Hey everyone. I'm sorry, but I've been fidgeting around with this script since last night and have made no progress understanding the functions.
The areas that are in brackets will be filled in with the according information, so don't worry about them. I'm making a script that converts .atom (xml format) files to Excel Spreadsheats for a project a friend of mine is doing. For whatever reason, when I do _XMLGetChildNodes("/feed"), it completely skips Link and Generator.
What I need to do is store the 'ID', 'JOINED DATE', 'ACTIVITY', and 'ACTIVITY DATE' content contained in each ENTRY (of which there are many hundred) into an array. I have attempted this, but to be honest, I'm having a lot of trouble understanding the functions in this UDF and when to use them based on the rather frustrating descriptions provided, as I am not an expert at xml structure.
Thank you to everyone who helps out and thank you for an awesome UDF

Your XML doesn't validate, you need a closing tag for 'feed' at the end of the document...like this </feed>

Your XML doesn't validate, you need a closing tag for 'feed' at the end of the document...like this </feed>

My bad, I took the first couple of ENTRY's from the feed for the example and forgot to close the first tag :mellow:

So, I was under the impression that

was still a node even though it has attributes. But this UDF says otherwise because tags that look like that ^ will not show up when I do _XMLGetChildNodes. What is a way that I can work around this? Am I using the wrong function?

My bad, I took the first couple of ENTRY's from the feed for the example and forgot to close the first tag

So, I was under the impression that
<div class='joinedDate'>Mon Dec 31 11:16:17 EST 2007</div>
was still a node even though it has attributes. But this UDF says otherwise because tags that look like that ^ will not show up when I do _XMLGetChildNodes. What is a way that I can work around this? Am I using the wrong function?

For some reason your xml won't parse with this line in the 'feed' namespace:

xmlns="http://www.w3.org/2005/Atom"

If you cut that out it works just fine.

#include "..\_XMLDomWrapper.au3"

$oXMLFile = _XMLFileOpen("atom.xml")

    Case 0
        ConsoleWrite("No Error" & @CRLF)
    Case 1
        ConsoleWrite("Parse Error" & @CRLF)
    Case 2
        ConsoleWrite("No Object" & @CRLF)
EndSwitch

$title = _GetFirstValue("//title")
ConsoleWrite("Title: " & $title & @CRLF)

$href = _XMLGetAttrib('//link', 'href')
ConsoleWrite('Href: ' & $href & @CRLF)

$id = _GetFirstValue("//id")
ConsoleWrite('Id: ' & $id & @CRLF)

;Retrieve count of entry nodes
$result = _XMLSelectNodes('//entry')
If IsArray($result) Then
    For $X = 1 to $result[0]
        ConsoleWrite("Entry "&$X&": " & _GetFirstValue('//entry[' & $X & ']/content/div[@class="id"]') & @CRLF)

Here is another way to work with the Atom XML without modifying the file itself.

#include "..\_XMLDomWrapper.au3"

$xmlns = 'xmlns:at="http://www.w3.org/2005/Atom" xmlns:taxo="http://purl.org/rss/1.0/modules/taxonomy/" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:sy="http://purl.org/rss/1.0/modules/syndication/" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"'

$oXMLFile = _XMLFileOpen("atom.xml", $xmlns)
Switch @error
    Case 0
        ConsoleWrite("No Error" & @CRLF)
    Case 1
        ConsoleWrite("Parse Error" & @CRLF)
    Case 2
        ConsoleWrite("No Object" & @CRLF)
EndSwitch

;MsgBox(0,"",$objDoc.documentElement.namespaceURI)

$title = _GetFirstValue("//at:title")
ConsoleWrite("Title: " & $title & @CRLF)

$href = _XMLGetAttrib('//at:link', 'href')
ConsoleWrite('Href: ' & $href & @CRLF)

$id = _GetFirstValue("//at:id")
ConsoleWrite('Id: ' & $id & @CRLF)

;Retrieve count of entry nodes
$result = _XMLSelectNodes('//at:entry')
If IsArray($result) Then
    For $X = 1 to $result[0]
        ConsoleWrite("Entry "&$X&": " & _GetFirstValue('//at:entry[' & $X & ']/at:content/at:div[@class="id"]') & @CRLF)
    Next
Else
    ConsoleWrite("NOT AN ARRAY" & @CRLF)
EndIf

;Get the first real value returned from the _XMLGetValue() return array. REQUIRED
Func _GetFirstValue($node)
    $ret_val = _XMLGetValue($node)
    If IsArray($ret_val) Then
        Return ($ret_val[1])
    Else
        Return SetError(1,3,0)
    EndIf

okay weaponx i used your examples you posted for the other guy as it helped me see where the errors were.. Basically I am pulling the .xml file from YOUTUBE but there was a parsing error.. i dont know why... So then i saved the file first then opened it and that solved the parsing issue..

Then i had to add the $xmlns variable you posted above then it was able to read the .xml file. I do not know what the $xmlns variable does but why does it allow it to read the file properly?

so i used your examples and where able to pull the info from the CHILD NODES but there are the other nodes in the media:group and could not find any example of extracting the data from those using the UDF?

i need to extract the data for all the nodes between the media:group from the videoinfo.xml file below

Declaring the namespace when you open the XML overrides the namespace definition in the root of the XML. When the root namespace is declared like this it causes problems:

xmlns='http://www.w3.org/2005/Atom'

So to override that you call _XMLFileOpen with a namespace declaration:

xmlns:anything='http://www.w3.org/2005/Atom'

This will make all nodes in your XML that don't have a namespace prefix identifiable with 'anything'. So if you have a node like this <node></node> you will now match it with 'anything:node'.

Make sense?

So you copy the namespace from your XML and paste it in the $xmlns variable:

$xmlns = "xmlns:gml='http://www.opengis.net/gml' xmlns:georss='http://www.georss.org/georss' xmlns:media='http://search.yahoo.com/mrss/' xmlns:batch='http://schemas.google.com/gdata/batch' xmlns:yt='http://gdata.youtube.com/schemas/2007' xmlns:gd='http://schemas.google.com/g/2005'"

EDIT: I'll test the code in just a bit, I have to eat lunch first.

okay i understand know a bit more on what you explained above.. so i added the ones below that youtube sends ad just added xmlns:at and it works..

$xmlns = 'xmlns:at="http://www.w3.org/2005/Atom" xmlns:gml="http://www.opengis.net/gml" xmlns:georss="http://www.georss.org/georss" xmlns:media="http://search.yahoo.com/mrss/" xmlns:batch="http://schemas.google.com/gdata/batch" xmlns:yt="http://gdata.youtube.com/schemas/2007" xmlns:gd="http://schemas.google.com/g/2005"'

so i am just trying to understand that the above links like engines that are called and then used to parse the data out of the XML file?

So i tried with logic to get some of the other values and it worked for the 3 of them :mellow:

$title = _GetFirstValue("//media:title")
ConsoleWrite("Title: " & $title & @CRLF)

$description = _GetFirstValue("//media:description")
ConsoleWrite("Description: " & $description  & @CRLF)

$keywords = _GetFirstValue("//media:keywords")
ConsoleWrite("Keywords: " & $keywords & @CRLF)

okay i figured the right syntax for the yt:duration and the player with the Attributes..

$player = _XMLGetAttrib("//media:player", "url")
ConsoleWrite("Player: " & $player & @CRLF)

$duration = _XMLGetAttrib("//yt:duration" , "seconds")
ConsoleWrite("Duration: " & $duration & @CRLF)

but how I get the 4 thumbnails media:thumbnail

this is all new to me so sorry if i do not know what the hell going on.. i am trying

thanks for the help as i understand it somewhat now i think..

Those are easy.

_XMLGetAttrib("//media:thumbnail[1]", 'url')

_XMLGetAttrib("//media:thumbnail[2]", 'url')

_XMLGetAttrib("//media:thumbnail[3]", 'url')

_XMLGetAttrib("//media:thumbnail[4]", 'url')

subfighter · November 11, 2008

thanks.. as i looked at your other example and was trying to figure it out with a loop

but no matter what tried the loop would not work at it always showed 4 of the same

CODE

For $X = 1 to 4

$thumbnail = _XMLGetAttrib("//media:thumbnail[' & $X & ']", "url")

ConsoleWrite("Duration: " & $thumbnail & @CRLF)

CODE

$thumbnail = _XMLGetAttrib("//media:thumbnail[1]", "url")

ConsoleWrite("Duration: " & $thumbnail & @CRLF)

$thumbnail = _XMLGetAttrib("//media:thumbnail[2]", "url")

ConsoleWrite("Duration: " & $thumbnail & @CRLF)

$thumbnail = _XMLGetAttrib("//media:thumbnail[3]", "url")

ConsoleWrite("Duration: " & $thumbnail & @CRLF)

$thumbnail = _XMLGetAttrib("//media:thumbnail[4]", "url")

thanks but now going to try to move on where there is 40 VIDEO INFO in the feed and extract.. so hopefully i can figure it out as i will have to run some loops like in your above example where counted the nodes then ran the loop..

thanks again...

THANKS AGAIN! there is the only thing i could not get to work is to get it to read the .xml using the $feedURL from the _INetGetSource as i commented out for now below. But it looks fine as it writes the XML to the console but it just gets a Parse Error when it tries to open it?

alright now the fun part :mellow: i tried doing some examples but got nowhere. As I really do not understand where to start..

So we got all the VIDEO DETAILS pulled from the XML file and it works great.

What i need now is i am doing a search with the YOUTUBE and getting a FEED of the results in XML. For the example here i am searching by author which is me (subfightercom) and its pulling 5 Videos from my library as i can have it get up to 50 videos at a time if you change the results variable as that is the limit YOUTUBE has on its FEED at a time.

so basically i started a new SearchAuthor.au3 based off the last example that we got working. So it Downloads the File author.xml from YouTube as saves the XML file to the script directory and saves 5 videos results.

so i changed the $xmlns variable like you showed me before and added the at: before the xmlns:at='http://www.w3.org/2005/Atom' so there are no problems or errors.

the basic structure of the xml file is like this now

<feed>
    <entry>
       VIDEO 1 DETAILS that we got from all the different Variables below
   </entry>
    <entry>
       VIDEO 2 DETAILS that we got from all the different Variables below
   </entry>
    <entry>
       VIDEO 3 DETAILS that we got from all the different Variables below
   </entry>
    <entry>
       VIDEO 4 DETAILS that we got from all the different Variables below
   </entry>
</feed>

i counted the _XMLGetNodeCount('/at:feed/at:entry') and it returns the proper number of 5 videos..

But this is where I am lost as I need it to cycle through the 5 videos and Grab the VIDEO DETAILS we did for one video. But i do not know if do this with a loop like FOR, or an ARRAY, or the process for it to count all the entries and cycle through them

entry [1] and get the VIDEO DETAILS

entry [2] and get the VIDEO DETAILS

entry [3] and get the VIDEO DETAILS

entry [4] and get the VIDEO DETAILS

entry [5] and get the VIDEO DETAILS

I understand we can grab entry[1] but is there a way to get all the video details that are below for it. then [entry 2], until it reaches the end of the entry [5]

any help or direction appreciated here..

You do this just like when you loop through media:thumbnail. I feel like you are taking two steps forward and one step back.

For $V = 1 to _XMLGetNodeCount('//at:entry')

    ; YOUTUBE VIDEO DETAILS
    $id = _GetFirstValue("//at:entry[" & $V & "]/at:id")
    ConsoleWrite("Id: " & $id & @CRLF)

    $published = _GetFirstValue("//at:entry[" & $V & "]/at:published")
    ConsoleWrite("Published: " & $published & @CRLF)

    $updated = _GetFirstValue("//at:entry[" & $V & "]/at:updated")
    ConsoleWrite("Updated: " & $updated & @CRLF)

    $title = _GetFirstValue("//at:entry[" & $V & "]/media:title")
    ConsoleWrite("Title: " & $title & @CRLF)

    $description = _GetFirstValue("//at:entry[" & $V & "]/media:description")
    ConsoleWrite("Description: " & $description  & @CRLF)

    $keywords = _GetFirstValue("//at:entry[" & $V & "]/media:keywords")
    ConsoleWrite("Keywords: " & $keywords & @CRLF)

    $player = _XMLGetAttrib("//at:entry[" & $V & "]/media:player", "url")
    ConsoleWrite("Player: " & $player & @CRLF)

    $duration = _XMLGetAttrib("//at:entry[" & $V & "]/yt:duration" , "seconds")
    ConsoleWrite("Duration: " & $duration & @CRLF)

    For $X = 1 to _XMLGetNodeCount("//at:entry[" & $V & "]/media:group/media:thumbnail")
        $url = _XMLGetAttrib("//at:entry[" & $V & "]/media:group/media:thumbnail[" & $X & "]","url")
        ConsoleWrite($url & @CRLF)
    Next

well what threw me off is getting the values with a different xmlns: instead having //at:entry for all of them.. Then it made sense to me.

What Is there a difference between b]//at:entry with 2 slashes and b]/at:entry with one slash

Also when we put the //at:entry what does the /at: actually stand for? Is that using the xmlns:at='http://www.w3.org/2005/Atom as the format to parse the file.

thanks again weaponx as your good at this and for anyone that needs an example just load the script below as it grabs the .xml from YOUTUBE and hopefully helps you out as weaponx showed me the light.

now time to make a gui for this :mellow:

#include <_XMLDomWrapper.au3>
#include <INet.au3>

InetGet("http://gdata.youtube.com/feeds/videos?author=subfightercom&max-results=15&start-index=1", "author.xml", 1)

$oXMLFile = _XMLFileOpen("author.xml", $xmlns)

Switch @error
    Case 0
        ConsoleWrite("No Error" & @CRLF)
    Case 1
        ConsoleWrite("Parse Error" & @CRLF)
    Case 2
        ConsoleWrite("No Object" & @CRLF)
EndSwitch

        $thumbnailurl = _XMLGetAttrib("//at:entry[" & $V & "]/media:group/media:thumbnail[" & $X & "]","url")
        ConsoleWrite($thumbnailurl & @CRLF)
    Next

ConsoleWrite("Processed: " & $V & @CRLF)
Sleep(2000) ;2 seconds

Next

    $ret_val = _XMLGetValue($node)
    If IsArray($ret_val) Then
        Return ($ret_val[1])

This is the best XML reference I have found:

http://www.w3schools.com/xpath/xpath_syntax.asp

These are pretty much the same:

'//at:feed/at:entry'

and

'/at:entry'

The single slash assumes you are matching inside of the root node.

I think the only reason we have to use the default namespace workaround is due to limitations in the MSXML2 object. Eltorro said he was working on a new version of this UDF that uses a different XML object, which may work differently.

Yes, looks like the whole site is down. Can anyone post the latest version of the UDF + example file? Thanks!

wraithdu · December 9, 2008

EDIT, n/m, found eltorro's google code page with the latest version, whew.

http://code.google.com/p/my-autoit/

Hmm, I could still use the latest example script though, it's not posted on the google code page.

Hi

I want to get the linenumber where an error occurs when the xml file is parsed and it has errors.

I tried $objDoc.parseError.line but it returns always 0.

Has anyone an idea how I can get the linenumber ?

thanks
