XML Can't Read Attributes

7 posts in this topic

Hey everyone,

This is driving me crazy I'm hoping someone can help me out.  I am trying to read from an XML that is created by a MS program (so I can't change anything about the file structure) but everytime I try to read attributes (or anything else) while the xmlns="" exists in the XML I can't get anything to work.

Reproducer;

Global $strFile
Global $DOMVERSION = -1
Global $objDoc

$sPath_PackageXML = ".\UserDeploymentConfiguration.xml"

$sret = _XMLFileOpen($sPath_PackageXML);, 'xmlns="http://schemas.microsoft.com/appv/2010/deploymentconfiguration"')
MsgBox(0, $sret, @error & " : " & @extended)
;the open ALWAYS works, have both used the namespace argument and not used

$temp_attrib = _XMLGetAttrib("/DeploymentConfiguration", "DisplayName")
MsgBox(0, "debug test : " & @error & " : " & @extended, $temp_attrib)
;this should work

I included the functions from the UDF for easier reproduction -- UDF found here ()

This XML doesn't work;

<?xml version="1.0"?>
<DeploymentConfiguration PackageId="testID" DisplayName="testDisplayname" xmlns="http://schemas.microsoft.com/appv/2010/deploymentconfiguration"></DeploymentConfiguration>
 

This XML does;

<?xml version="1.0"?>
<DeploymentConfiguration PackageId="testID" DisplayName="testDisplayname" ></DeploymentConfiguration>
 

I'm not against using something else other then the XML DOM, so any suggestions welcome.  I'm at the point I might go back to fileread operations.

Thanks in advance.

Both work for me:

$oXML = ObjCreate("Microsoft.XMLDOM")

$xml = '<?xml version="1.0"?><DeploymentConfiguration PackageId="testID" DisplayName="testDisplayname1" xmlns="http://schemas.microsoft.com/appv/2010/deploymentconfiguration"></DeploymentConfiguration>'
$oXML.loadxml($xml)
ConsoleWrite($oXML.xml & @CRLF)
For $oConfig in $oXML.selectNodes("//DeploymentConfiguration")
    $sDisplayName = $oConfig.getAttribute('DisplayName')
    ConsoleWrite($sDisplayName & @CRLF)
Next

$xml = '<?xml version="1.0"?><DeploymentConfiguration PackageId="testID" DisplayName="testDisplayname2" ></DeploymentConfiguration>'
$oXML.loadxml($xml)
ConsoleWrite($oXML.xml & @CRLF)
For $oConfig in $oXML.selectNodes("//DeploymentConfiguration")
    $sDisplayName = $oConfig.getAttribute('DisplayName')
    ConsoleWrite($sDisplayName & @CRLF)
Next

output:

<?xml version="1.0"?>
<DeploymentConfiguration PackageId="testID" DisplayName="testDisplayname1" xmlns="http://schemas.microsoft.com/appv/2010/deploymentconfiguration"></DeploymentConfiguration>

testDisplayname1
<?xml version="1.0"?>
<DeploymentConfiguration PackageId="testID" DisplayName="testDisplayname2"></DeploymentConfiguration>

Hey jdelaney,

Thanks a lot!  I tried using microsoft.xmldom (actually from one of your posts) but turns out I missed that you have to pass the XML as a string... I kept feeding it a filename...Doh!  >_<  .  Is the Microsoft.XMLDOM better/worse, newer or older compared to Msxml2.DOMDocument I am using from eltorro's UDF?

Any ideas on why it only works with Microsoft.XMLDOM?

 

Thanks so much for the help, really appreciate it.

You can load an XML file, just pass in the file as the param, and change .xmlload to .xml...or maybe just .load...I forget (your own quick google search if interested)

For my samples, I don't do that, so it's a stand alone script

The MSXML2 version 3.0 works, none of the others do though:

$oXML = ObjCreate("Microsoft.XMLDOM")

$xml = '<?xml version="1.0"?><DeploymentConfiguration PackageId="testID" DisplayName="testDisplayname1" xmlns="http://schemas.microsoft.com/appv/2010/deploymentconfiguration"></DeploymentConfiguration>'
$oXML.loadxml($xml)
ConsoleWrite($oXML.xml)
For $oConfig in $oXML.selectNodes("//DeploymentConfiguration")
    $sDisplayName = $oConfig.getAttribute('DisplayName')
    ConsoleWrite($sDisplayName & @CRLF & @CRLF & @CRLF)
Next

$xml = '<?xml version="1.0"?><DeploymentConfiguration PackageId="testID" DisplayName="testDisplayname2" ></DeploymentConfiguration>'
$oXML.loadxml($xml)
ConsoleWrite($oXML.xml & @CRLF)
For $oConfig in $oXML.selectNodes("//DeploymentConfiguration")
    $sDisplayName = $oConfig.getAttribute('DisplayName')
    ConsoleWrite($sDisplayName & @CRLF)
Next


For $i = 8 To 0 Step -1
    If FileExists(@SystemDir & "\msxml" & $i & ".dll") Then
        $oXML = ObjCreate("Msxml2.DOMDocument." & $i & ".0")
        If IsObj($oXML) Then
            $DOMVERSION = "Msxml2.DOMDocument." & $i & ".0"
            ConsoleWrite($DOMVERSION & @CRLF)
        Else
            ContinueLoop
        EndIf
    Else
        ContinueLoop
    EndIf

    $xml = '<?xml version="1.0"?><DeploymentConfiguration PackageId="testID" DisplayName="testDisplayname' & $DOMVERSION & '-a" xmlns="http://schemas.microsoft.com/appv/2010/deploymentconfiguration"></DeploymentConfiguration>'
    $oXML.loadxml($xml)
    ConsoleWrite($oXML.xml)
    For $oConfig in $oXML.selectNodes("//DeploymentConfiguration")
        $sDisplayName = $oConfig.getAttribute('DisplayName')
        ConsoleWrite($sDisplayName & @CRLF)
    Next

    $xml = '<?xml version="1.0"?><DeploymentConfiguration PackageId="testID" DisplayName="testDisplayname' & $DOMVERSION & '-b" ></DeploymentConfiguration>'
    $oXML.loadxml($xml)
    ConsoleWrite($oXML.xml)
    For $oConfig in $oXML.selectNodes("//DeploymentConfiguration")
        $sDisplayName = $oConfig.getAttribute('DisplayName')
        ConsoleWrite($sDisplayName & @CRLF)
    Next

    ConsoleWrite(@CRLF & @CRLF)
Next

no idea why...output:

Thanks for going this far with it... I'm trying to figure out the difference of why it would work in 3 but not 6, and I'll post back on this thread if I get anywhere.  And PS you were right , using just load() I can load up an XML based on filepath, instead of passing a string with loadxml().

      Hi. I'm trying to write a xml. Here is my code:

How will it be going right?

      I was asking @eltorro serveral times for any support  for XML DOM wrapper (COM) - with no success  
          So I took matters into my hands ..... I want to present XMLWrapperEx.au3 - BETA Version
      Want to join to the project ?
       
      Here is some description:

This is BETA VERSION (all could be changed) !!!!!!!!! . . . WORK IN PROGRES INFORMATION: For now 2015-09-01 the descripion (Function Header) can not entirely correctly describe the function. TODO: in many places I used "TODO" as a keyword to find what should be done in future . I want to: PREVENT THIS: The unfortunate nature of both the scripts is that the func return results are strings or arrays instead of objects. .     I want to: USE THIS CONCEPT:     .   All function should use Refernce to the object as first Function parameter     .   All function should return in most cases objects. There should be separate functions to Change Object collection to array     .   All function should use COM Error Handler in local scope.     .   All function should return @error which are defined in #Region XMLWrapperEx.au3 - @ERROR Enums     .    All function should have the same naming convention     .    All variables should have the same naming convention     .    There should not to be any Global Variable - exception is $g__oXMLDOM_Events     .   It should be possible easy to use XML DOM Events     .        https://msdn.microsoft.com/en-us/library/ms764697(v=vs.85).aspx     .   It should be possible easy to Debug     .    Ultimately, you should be able to do anything with your XML without having to use your own Error Handler. #CE

      Hi Guys, 
      Since I'm able to get a Dell equipment warranty status thanks to my API key, I'm using an UDF to extract data from an XML file and get the end date. > 
      Thing is, when using InetGet, the original file is in JSON format and the UDF is not working anymore, even if I download the file with the xml extension. Therefore, and when I manually download the page with Chrome, I have a proper XML file where the UDF is working fine.
      Here's my code:
      I even tried to convert the json to xml > https://www.autoitscript.com/forum/topic/185717-js-json-to-xml/
      I took a look here https://www.autoitscript.com/forum/topic/104150-json-udf-library-fully-rfc4627-compliant/ but I don't understand anything :/
       
      The XML read UDF is just perfect for my needs but I'm stuck here... 
      Thanks for any help you can provide

      Alright, this is going to be a rather long explanation so bear with me.
      What I am trying to to is build a GUI program that, in the end, will look like this:
      The middle Frame is for displaying a desktop icon and the right frame is for displaying a selected image.
      The XML file I am using looks like this:
      <list> <item id="1"> <ico>Path\to\icon1<\ico> <img>Path\to\image1<\img> <exe>Path\to\program1<\exe> <label>UserDefinedLabel1<\label> <\item> <item id="2"> <ico>Path\to\icon2<\ico> <img>Path\to\image2<\img> <exe>Path\to\program2<\exe> <label>UserDefinedLabel2<\label> <\item> <\list> What I want this program to do is when I highlight an item in the listbox (which btw is displaying the <label> value associated with the item) I want the displayed icon and image to change to the ones associated with that entry. 
      Also I would like to include an additional dialog to open when the 'ADD' button is clicked that will add entries to the XML file that looks like this:

       
      The main problem I am running into is that I do not know much about XML and how to parse it into dynamic variables that can change based off of selection.
      Any help is appreciated.
       
       
       
      10-29-16 EDIT: For all intents and purposes, I basically want to create something similar to PStart, but with a preview pane with a customizable image for each item in it.
