Manipulation XML using XPath for VBScript/UFT

This article explains how to extract information from an xml file based on the element xpath using Microsoft.XMLDOM and VBSript. You can try using the code as shown below.

''---------------------------------------------------------------------------------
'' Step 1 : Copy the content removing comments in a file and save the file
''----------------------------------------------------------------------------------

'' --------------File Content ------------------------------------------------------
''XMLTextFile = "<books><name>mybook</name><price>50</price><Author rating="high">matt</Author>
''<name>his book</name><price>150</price><Author rating="low">henry</Author>
''<name>twist</name><price>550</price><Author rating="high">henry</Author></books>"

''-------------Call the functions with Parameters------------------------------------
msgbox getXMLTextFileValue("d:\testdta.xml","//price")
msgbox getXMLTextFileValue("d:\testdta.xml","//Author[@rating='high']")
msgbox getxmlAttributeValue("d:\testdta.xml","//Author","rating")
call getAllNodeValues("d:\testdta.xml","//Author")
''-----------------------------------------------------------------------------------

'' Function 1 - Reading the node text
''Arguments - FileName and xpath of node

''-----------------------------------------------------------------------------------
function getXMLTextFileValue(XMLTextFile,NodeXpath)
Set objXML = CreateObject("Microsoft.XMLDOM")

if(boolxmlParse) then
 objXML.setProperty "SelectionLanguage", "XPath"
 set objXML_node = objXML.selectSingleNode(NodeXpath)
        getXMLTextFileValue = objXML_node.text
 else
 msgbox "issue in xml file"
End If
End Function

''-----------------------------------------------------------------------------------

'' Function 1 - Reading the node attribute value
''Arguments - FileName and xpath of node. attribute Name of which value is to be returned

''-----------------------------------------------------------------------------------

        getxmlAttributeValue = objXML_node.getAttribute(attributeName)
 else

End If
End Function

''-----------------------------------------------------------------------------------

'' Function 1 - Reading the value of all the matching nodes

End Function
