; also uses google chart api for some a little trend display

I get an error in expression at this line:

$objNodeList = $obj.documentElement.selectNodes($path)

which URL did you use for the data ?

could you post the xml file? or check it in ie browser if its valid? or post the error`?

Sure.. Here is my error:

C:\Google Weather.au3 (192) : ==> Error in expression.:

$objNodeList = $obj.documentElement.selectNodes($path)

$objNodeList = ^ ERROR

->12:17:40 AutoIT3.exe ended.rc:1

>Exit code: 1 Time: 4.027

Here is the url I am using:

http://www.google.com/ig/api?weather=tulsa

[nobbe]

seems like it misinterprets something ( tulsa works for me)

i update first post, maybe it helps? (comes with all the codes i used for it and compiled version)

which autoit version do you use?

I'm getting the same error

Line 194

$objNodeList = $obj.documentElement.selectNodes($path)

$objNodeList = ^ ERROR

Error: Error in expression.

That's using the code you provided (Berlin)

[nobbe]

can you check the xml file if it gets loaded correctly in ie browser - when it displays an error when loading the xml file its malformed XML for some reason.??

please try the updated first post source now . it Could be?? the $obj returned from

$obj = _XMLFileOpen($infile)

doesnt stay the same as the

$objDoc used in the _xml_domwrapper?

so i include now all code from _domwrapper in the regular code

Now it works for me. The XML DOM wrapper code that I was using returned success/failure from the file open call whereas your version is obviously expecting an object. Might be worth pointing to the right version of the include file if you want to go back to using it.

Much better. It still has a couple of issues.

1 - Remove the GUI positioning or set it relative to desktop size. When it opens most of the GUI is below the bottom of my desktop

2 - it worked fine for Tulsa but for my locale, the image is not there for current conditions.

3 - You shouldn't automatically be changing to Centigrade. Most American users won't appreciate that. The °F and °C are both returned in the xml page (at least for me) as temp_f data and temp_c data.

The xml is not mal-formed

I'm playing with some work-arounds to using the DOM wrapper.

[nobbe]

code update , so i assume the obj code are returned incorrectly from _domwrapper.udf for some reason?

- now sets pos to upper left screen pos

- celsius & fahrenheit by using

Global $b_use_celsius = 1 ; 1 for celsius or 0 for farenheit

Again, you have improved it. However it still misses the icon for My locale and it is in the XML under cirrent conditions.

<icon data="/images/weather/sunny.gif"/>

I'm wondering if part of this may not be associated with Google regionalization.

Sorry, been at work.. The new code seems to work fine for me now.. Nice script.

i dont know .. unfortunately i couldnt find much information about the google apis

also i get different results when i use IE browser to retrieve the data (here i already get the german data localized)

when is use inetget() i get englisch data

Nice idea for script!

I also get english texts by InetGet.

I tried to make workaround by 

;~   InetGet($url, @ScriptDir & "\weather.xml", 1, 0); vrati anglickou verzi popisku
 $oIE = _IECreate ($url, 0, 0)
 $sText = _IEBodyReadText ($oIE)
 $sText = StringReplace($sText, '- <', '  <')
 $sText = StringReplace($sText, @CRLF & ' ', '')
 $sText = StringReplace($sText, '> <', '><')
 $sText = StringReplace($sText, '>  <', '><')
 $sText = StringStripWS($sText,1+2)
 FileDelete(@ScriptDir & "\weather.xml")
 FileWrite(@ScriptDir & "\weather.xml", $sText)

but it's not working well. XML parsing show errors.

Nice script, I enjoy these web service based scripts. Keep up the good work!

Well, I'm still playing with a work-around to the DOM wrapper using StringRegExp. I dropped the InetGet() in favor of _InetGetSource() which also returns the English version. Then To make it simpler to parse I used a StringReplace in it.

$sData = StringRegExp(StringReplace(_InetGetSource($sUrl), "><",">" & @CRLF & "<"), "(?i)(?s)(<weather.*weather>)", 1)
If NOT @Error Then
   $sData = $sData[0]
Else

EndIf
ClipPut($sData);; For testing only

From there I can call various functions to return the values that you need. I'm still curious why the image is missing for me on local conditions using your code. I don't see anything obviously wrong.

I also made the following change in your code for setting the Window Title

;WinSetTitle($GUI, "", "google weather for " & $town);

    $url = "http://www.google.com/ig/api?weather=" & $town;& "&hl=de";
    $url = _URLEncode($url)
    ConsoleWrite($url & @CRLF);

   ; save into TEMP file first to check the XML data by hand
   ;InetGet("http://www.google.com/ig/api?weather=Berlin" & '\&' & "hl=de", @ScriptDir & "\weather.xml", 1, 0)

    InetGet($url, @ScriptDir & "\weather.xml", 1, 0)

   ;$result = _INetGetSource($url)
   ;ConsoleWrite($result);

   ; now xml file in local drive @scriptdir

    $objDoc = _XMLFileOpen($infile)
    
    $town = _XMLGetAttrib("//xml_api_reply/weather/forecast_information/city", "data");
    WinSetTitle($GUI, "", "Google Weather for " & $town);

[nobbe]

i found different url for the localized feeds (now inetget works fine with my towns and language)

Feed Url's

UK English: http://www.google.co.uk/ig/api?weather=

But there are some problems:

- XML must be converted from OEM to ANSI code page

- _XMLFileOpen() show error: An invalid character was found in text content.

Here is Oem2Ansi()

Func Oem2Ansi($text)
 $text = DllCall('user32.dll','Int','OemToChar','str',$text,'str','')
 Return $text[2]
EndFunc

Here is my XML czech content:

I think I must encode czech letters somehow to be able use _XML parsing. Edited April 9, 2009 by Zedna

- _XMLFileOpen() show error: An invalid character was found in text content.

I think I must encode czech letters somehow to be able use _XML parsing.

i suspect the ms xml parser is rather picky ..

the same happens to me here when i use the .com server with "&hl=de"

; http://www.google.com/ig/api?weather=Berlin&hl=de -> this is buggy here??

its shows the same error

"An invalid character was found in text content"

; http://www.google.com/ig/api?weather=Berlin -> this works??
