Using XMLDomWrapper.au3 to Get Attributes

Recommended Posts

leegold

Hi,

I've been looking at XPath tutorials and trying to find Autoit example to solve a simple problem, I must be missing something here and would be grateful for help.

Given:

#include <_XMLDomWrapper.au3>

_XMLFileOpen("c:\xmltest1.xml")

local $ids =_XMLGetAttrib('/r/line', "b")
ConsoleWrite(@LF & "=====" & $ids & "=====" & @LF)

;~ <r>
;~  <line a="1" b="2">hi</line>
;~  <line a="3" b="4">hey</line>
;~  <line a="5" b="6">hello</line>
;~ </r>

and console says: =====6=====

But I want to get all values for "b=" I want to get from the XML file 2,4,6

I tried the _XMLGetAllAttrib function but if that's the way to do it then I'm doing something wrong too. I've tested the XPath:  /r/line/@b  in Notepad++ XML Plugin and this XPath gives all the b values. If anyone could enlighten me I would appreciate it. Thanks. How do I get all the b values out of the XML?

Hi,

I know you are wanting to do this with XPATH (Maybe someone can help with this), I have tried with XMLDomWrapper and had no luck. But for the sake of a quick answer to your problem. You could try the below method, Returns an Array with Results.

#include <Array.au3>

$vXML = '<r>'
$vXML &=  '<line a="1" b="2">hi</line>'
$vXML &=  '<line a="3" b="4">hey</line>'
$vXML &=  '<line a="5" b="6">hello</line>'
$vXML &= '</r>'

$vRequest = StringRegExp($vXML, '<line\sa=".*?"\sb="(.*?)">.*?</line>', 3)

_ArrayDisplay($vRequest)

Also managed to get it working by declaring the XMLDOM Object

#include <Array.au3>

$vXML = '<r>'
$vXML &=  '<line a="1" b="2">hi</line>'
$vXML &=  '<line a="3" b="4">hey</line>'
$vXML &=  '<line a="5" b="6">hello</line>'
$vXML &= '</r>'

Local $vXPath = '//r/line'
Local $vAttrib = 'b'

$vXMLObj = ObjCreate('Microsoft.XMLDOM')
$vXMLBody = $vXMLObj.loadXML($vXML)
$vXMLNodeList = $vXMLObj.selectNodes($vXPath)
$vXMLNodeLength = $vXMLNodeList.length

Local $vArr[$vXMLNodeLength]

    For $i = 0 To $vXMLNodeList.length - 1
        $vGetAttrib = $vXMLNodeList.item($i).getAttribute($vAttrib)
        $vArr[$i] = $vGetAttrib
    Next


_ArrayDisplay($vArr)

awww, beat me to it...posting anyways to show collection loops (not storing in an array)

$sXML = '<r><line a="1" b="2">hi</line><line a="3" b="4">hey</line><line a="5" b="6">hello</line></r>'
$oXML = ObjCreate("Microsoft.XMLDOM")
$oXML.LoadXML($sXML)
$oAttribCol = $oXML.selectNodes( '//line/@b' )

For $oAttrib In $oAttribCol
    ConsoleWrite($oAttrib.value & @CRLF)
Next

ConsoleWrite(@CRLF & "Take 2" & @CRLF)

$oNodeCol = $oXML.selectNodes( '//line' )
For $oNode In $oNodeCol
    ConsoleWrite($oNode.getAttribute("b") & @CRLF)
Next

I was looking for something like this - just put in the correct XPath and get the results. This "Microsoft.XMLDOM" solution worked like a charm. Thank you.

      Hi All,
      This is purely an XML Language question. I need to understand how I can add a value/element in between another XML element. 
      Code below shows the XML file. The info tag has the elements already inserted.
      <Configuration xmlns="http://schemas.datacontract.org/2004/07/Modules.Reporting.DataContracts.LineItems" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"> <GenConf> <Info>ID, Site, Name , Site_ID</Info> </GenConf> </Configuration> Now, I want to add a value from a node group into this code. Something like below. But the example below does not work.
      Any suggestions?
       
      <Configuration xmlns="http://schemas.datacontract.org/2004/07/Modules.Reporting.DataContracts.LineItems" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"> <GenConf> <Info>ID, Site, a/@id, Name , Site_ID</Info> </GenConf> </Configuration> <ProductName> <a id="Windows Server"/> </ProductName>

      Hello guys,
       
      This XML things are driving me crazy...
      Please let me know how can I use the _XMLGetAttrib function... I've tried every possible way that I've read on the forum and I cannot succeed reading an attribute.
       
      The XML looks like bellow:
       
      <?xml version="1.0" encoding="UTF-8"?>
      <BATCH attr1= "aaa" attr2="bbb" attr3="ccc">
           <Node1 attr1="aaa" attr2="bbb" attr3="ccc" attr4="ddd" attr5="" attr6="eee" attr7="fff" attr8="ggg"/>
           <Node2 attr1="aaa" attr2="" attr3="" attr4="ddd"/>
           <Node3 attr1="" attr2="" attr3="ccc" attr4="" attr5="" attr6="eee"/>
           <Panel attr1="aaa" STATUS="BBB" attr3="ccc" attr4="ddd" attr5="" attr6="eee">
                <Node5 attr1="aaa" attr2="bbb" attr3="ccc" attr4="ddd" attr5="" attr6="eee" attr7="fff" attr8="ggg"/>
                .............................................................................................................................................................................
           </Panel>
      </Batch>
       
      I need to read the value of STATUS form the Panel node.
       
      Could you please help me?

      Can anyone assist with creating/modify/delete XML Nodes/Child Nodes?
      Have a document for example:
      <ConfigData> <parameter> <name>Setting One</name> <value>10</value> </parameter> <parameter> <name>IPAddress</name> <value>192.168.1.1</value> </parameter> <parameter> <name>Setting One</name> <value>200</value> </parameter> <parameter> <name>Setting Three</name> <value>300</value> </parameter> </ConfigData> Would like to add another node parameter/name, parameter/value, but unsure how to, when there are multiple instances with the same tagname for example, would like to add the following if the nodes do not already exist:
      <parameter> <name>UserPreferredLanguage</name> <value>English</value> </parameter> Currently using the following to check and delete/modify existing nodes, was thinking of placing the name and value into a 2d array and then using a true/false in a 3rd column to return if the setting was found and modified or not, so I can decide whether I need to create the nodes or not, but I'm hoping there is a simpler way.\
      Any assistance would be much appreciated.
      PS: Have also written this with the XML Dom Wrapper UDF but still unsure how to proceed with checking nodes and creating them if they're missing, also couldn't find a function to delete a full node + parent using selectNodes, hence the custom __XML_DeleteNode function.
      Thanks
