@mLipok This document will not be parsed, unless you remove the link tag:

<html>
  <head>
    <meta charset="utf-8">
    <link href="main.css" rel="stylesheet">
    <title>My test page</title>
  </head>
  <body>
    <p>This is my page</p>

@TheDcoder so you post XML but where you post your au3 code to reproduce your problem ?

TheDcoder · July 13, 2018

@mLipok Sorry, I was on Linux and I was planning to write a reproducer script when I switch to Windows. Here is the script:

You can see that in the output it says "End tag 'head' does not match the start tag 'link'", which means the parser is unable to deal with single/void/non-closing tags

I guess msxml is not made for parsing HTML... problems start popping up as soon as I start fixing them . Here are some functions people might find useful if they are working with HTML...

; Use this function to remove the contents of script tags (some symbols confuse the parser)
Func StripScriptTagContent(ByRef $sHtml)
    $sHtml = StringRegExpReplace($sHtml, '(*UCP)(?si)<script.*?>.*?<\/script>', '<script>Truncated</script>')
EndFunc

; Use this function to automatically generate end tags for void tags, a bad workaround and will generate invalid HTML, but it works for analysis purposes
Func CleanseVoidTags(ByRef $sHtml)
    Local Static $aVoidTags = ['area', 'base', 'br', 'col', 'embed', 'hr', 'img', 'input', 'link', 'meta', 'param', 'source', 'track', 'wbr']
    For $sTag In $aVoidTags
        $sHtml = StringRegExpReplace($sHtml, '(*UCP)(?si)(<' & $sTag & ' .*?>)', '\0</' & $sTag & '>')
    Next
EndFunc

The parser has started to complain about undefined entities (Reference to undefined entity 'nbsp').

I guess I will write my own parser for now... sigh.

@mLipok Can I generate a XML file with doctype declare such as '<!DOCTYPE SCHEMA SYSTEM "HGWSPZJK.dtd">' by using XML.AU3

the whole xml file like as follow:

<?xml version="1.0" encoding="GBK"?>

<!DOCTYPE SCHEMA SYSTEM "HGWSPZJK.dtd"> ;I can not generate this line

</Records>

</TAXPAYER>

</SCHEMA>

someone said that use CreateDocumentType https://docs.microsoft.com/zh-cn/dotnet/api/system.xml.xmldocument.createdocumenttype?redirectedfrom=MSDN&view=netframework-4.7.2#System_Xml_XmlDocument_CreateDocumentType_System_String_System_String_System_String_System_String_

someone said that use loadxml

I confused that can I only use FileWrite () write the string as above and save as test.xml

thanks

Hi @mLipok,

Thank you so much for the work you have done with XML.au3. I typically do not message the authors of UDFs, but I have struggled with this issue for weeks. I do not have a problem retrieving the results of an API call to FedEx, my problem is traversing the nodes. Can you please post a SOAP example to your XML_Example_XML_Files, or just assist with the issue I am having. Attached is the XML response and below are the code snippets. Current using XMLDomWrapper.au3, but plan to shift to XML.au3.

Example: I cannot get to node:

Hi @mLipok,

I just wanted to make sure you were talking about the question I asked. I'm still researching solutions, but not having any luck. At one point there was a SOAPSDK3.0 Toolkit published by Microsoft, but that is no longer supported.

Thanks for your help.

Their solution was to access the node by relative XPath (i.e. tag="//xbe:ConversionRateResult"). Their response XML has xbe as the namespace, but my xml file I don't have namespaces to reference. Please see the track_received.xml file attached in the original post. Thank you

Actually the track_received.xml file has 2 namespaces (xmlns) needed to access the node. The following example shows one way that you can use xml.au3 functions to access that node.

I have been having a bit of trouble the last couple of days with getChildNodes and just noticed now that I am also having the same problem using the supplied:

XML_1.1.1.13\XML__Examples.au3

Example 6 throws the following:

Quote

from line 272 to give me an error I get this:

1.jpg.903489b08d58437826ddaa7e57cd9182.jpg

Am I doing something wrong? This is the same when I use my own XML or any other XML file.

Thanks

As it relates to the COM error in example 6, If I am looking at the same version as you are, then line 274 in the xml_example.au3 is:

_ArrayDisplay($aNodesColl, 'Example_6__XML_GetChildNodes: ' & 'Length=' & $oNodesColl.length & '   XPath=' & $oNodesColl.expr)

There appears to be a slight error in example 6. In example 6, $oNodesColl is an IXMLDOMNodeList object. IXMLDOMNodeList objects do not have an "expr" property. Therefore, if you just remove the reference to $oNodesColl.expr from line 274, you shouldn't get that COM error. You can read more about the IXMLDOMNodeList object and its members HERE.

So just change line 274 to something like below and you will not get the COM error in example 6:

_ArrayDisplay($aNodesColl, 'Example_6__XML_GetChildNodes: ' & 'Length=' & $oNodesColl.length)

As for the 2nd error on line 272, I don't get that error when running example 6. You would probably get a similar error if you moved the xml_examples.au3 file to a different location, without the supporting XML_Example_XML_Files folder structure, and tried to execute it. That would be because it couldn't find the XML file that it needs.

Thanks for the first bit. I did try without both Length and Expr in testing but put it back to normal when writing up this post.

As for the other error, I haven't moved the XML_Example.au3 anywhere. Freshly unzipped with books.xml displaying its contents from the first msgbox. 1.PNG.bcc5fa3baf760cc4b0e4bff531cea023.PNG

Func Example_6__XML_GetChildNodes()

    ; first you must create $oXmlDoc object
    Local $oXMLDoc = _XML_CreateDOMDocument(Default)

    ; Load file to $oXmlDoc
    Local $sXmlFile = @ScriptDir & "\XML_Example_XML_Files\MSDN\books.xml"
    _XML_Load($oXMLDoc, $sXmlFile)

    ; simple display $oXmlDoc - for checking only
    MsgBox($MB_SYSTEMMODAL + $MB_ICONINFORMATION, 'Example_6__XML_GetChildNodes', _XML_TIDY($oXMLDoc))

    ; selecting nodes
    Local $oNodesColl = _XML_GetChildNodes($oXMLDoc, "//book")

    ; change Nodes Collection to array
    Local $aNodesColl = _XML_Array_GetNodesProperties($oNodesColl)
    If @error Then
        MsgBox($MB_SYSTEMMODAL + $MB_ICONINFORMATION, 'ERR:' & @error & ' EXT:' & @extended, XML_My_ErrorParser(@error, @extended))
    EndIf
    _ArrayDisplay($aNodesColl, 'Example_6__XML_GetChildNodes: ' & 'Length=' & $oNodesColl.length)

EndFunc    ;==>Example_6__XML_GetChildNodes

MsgBox($MB_SYSTEMMODAL + $MB_ICONINFORMATION, 'Example_6__XML_GetChildNodes', _XML_TIDY($oXMLDoc)) displays the contents of the XML loaded (books.xml), $oNodesColl gets returned as being successful in that it is an object, not null etc...and then _XML_Array_GetNodesProperties() throws that screenshot error I posted in my last post.

I tried downloading this on 2 other fresh PCs and I had the same result. I'm just stumped at this point...especially since you didn't get the error when running the script and its throwing the same error when I try and use _GetChildNodes() in my own script reading my own XML which I verified has loaded to $oXMLDoc 😮

Sorry about this

If you are able to get the error over and over, can you try adding this slightly modified version of the example 6 function to the xml_examples.au3 file and executing it? I named it Example_6A__XML_GetChildNodes(). It just has 3 additional ConsoleWrite lines that will give me a little more info about $oNodesColl. Please post the result of the consolewrites.

Func Example_6A__XML_GetChildNodes()

    ; first you must create $oXmlDoc object
    Local $oXMLDoc = _XML_CreateDOMDocument(Default)

    ; Load file to $oXmlDoc
    Local $sXmlFile = @ScriptDir & "\XML_Example_XML_Files\MSDN\books.xml"
    _XML_Load($oXMLDoc, $sXmlFile)

    ; simple display $oXmlDoc - for checking only
    MsgBox($MB_SYSTEMMODAL + $MB_ICONINFORMATION, 'Example_6A__XML_GetChildNodes', _XML_TIDY($oXMLDoc))

    ; selecting nodes
    Local $oNodesColl = _XML_GetChildNodes($oXMLDoc, "//book")
    If @error Then Return SetError(@error, @extended)
    ConsoleWrite(StringFormat("$oNodesColl is a vartype of %s", VarGetType($oNodesColl)) & @CRLF)
    ConsoleWrite(StringFormat("$oNodesColl.length = %s", $oNodesColl.length) & @CRLF)
    ConsoleWrite(StringFormat("ObjName($oNodesColl) = %s", ObjName($oNodesColl, 1)) & @CRLF)

    ; change Nodes Collection to array
    Local $aNodesColl = _XML_Array_GetNodesProperties($oNodesColl)
    If @error Then Return SetError(@error, @extended)
    _ArrayDisplay($aNodesColl, 'Example_6__XML_GetChildNodes: ' & 'Length=' & $oNodesColl.length)

EndFunc    ;==>Example_6__XML_GetChildNodes

The ConsoleWrites should look like this. Does yours look the same?

$oNodesColl is a vartype of Object
$oNodesColl.length = 6
ObjName($oNodesColl) = IXMLDOMNodeList

For sure.

My code I used (In case I missed something drastic 😮

Func Example_6__XML_GetChildNodes()

    ; first you must create $oXmlDoc object
    Local $oXMLDoc = _XML_CreateDOMDocument(Default)

    ; Load file to $oXmlDoc
    Local $sXmlFile = @ScriptDir & "\XML_Example_XML_Files\MSDN\books.xml"
    _XML_Load($oXMLDoc, $sXmlFile)

    ; simple display $oXmlDoc - for checking only
    MsgBox($MB_SYSTEMMODAL + $MB_ICONINFORMATION, 'Example_6__XML_GetChildNodes', _XML_TIDY($oXMLDoc))

    ; selecting nodes
    Local $oNodesColl = _XML_GetChildNodes($oXMLDoc, "//book")
    If @error Then Return SetError(@error, @extended)
    ConsoleWrite(StringFormat("$oNodesColl is a vartype of %s", VarGetType($oNodesColl)) & @CRLF)
    ConsoleWrite(StringFormat("$oNodesColl.length = %s", $oNodesColl.length) & @CRLF)
    ConsoleWrite(StringFormat("ObjName($oNodesColl) = %s", ObjName($oNodesColl, 1)) & @CRLF)

    ; change Nodes Collection to array
    Local $aNodesColl = _XML_Array_GetNodesProperties($oNodesColl)
    If @error Then
        MsgBox($MB_SYSTEMMODAL + $MB_ICONINFORMATION, 'ERR:' & @error & ' EXT:' & @extended, XML_My_ErrorParser(@error, @extended))
    EndIf
    _ArrayDisplay($aNodesColl, 'Example_6__XML_GetChildNodes: ' & 'Length=' & $oNodesColl.length)

EndFunc    ;==>Example_6__XML_GetChildNodes

Console Output:

$oNodesColl is a vartype of Object
$oNodesColl.length = 13
ObjName($oNodesColl) = IXMLDOMNodeList

Different length than yours but the object is of the same type??

I am still getting that screenshot error too (I know consolewrite's wouldn't be fixing that and it was for debug purposes):
