I am new in XML. But I have done coding in VBA, C, and HTML. I am using VBA to extract data from an xml file. I use Xpathbuilder
to generate Xpath queries for my work. However, some Xpath queries are causing errors in my program. As I am new in xml and its standards I am not sure what is causing them. Answers to the following questions might help me in understanding these problems better
. Can you please help me? Thanks.
1. Which version of xml am I using?
In my program I declare variables as shown here. Dim oDoc As MSXML2.DOMDocument, Dim oNodeList As msxml2.IXMLDOMNodeList. Also, in Refrences of the VBA environment I have selected Microsoft xml.V6.0. I have Microsoft XP and Office 2003 SP2.
2. Why the SelectionLanguage property is not working?
When I put the following statement in my code, the selectnodes statement gives me an error. Selectnodes work fine without this statement. I don’t know why this is happening.
oDoc.setProperty "SelectionLanguage", "XPath"
3. Why the Selectnodes statement is not working for a few queries?
I am using this statement:
Set oChildren = oDoc.selectNodes(Path). This statement works for simple queries such as
Path = /FSK:Research/FSK:Product/FSK:Context/FSK:IssuerDetails/FSK:Issuer/FSK:SecurityDetails/FSK:Security
But causes an error for
Or Path =
Note that I have verified these paths using Xpathbuilder.
I am also attaching my code below.
Dim oDoc As msxml2.DOMDocument
Dim fSuccess As Boolean
Dim oRoot As msxml2.IXMLDOMNode
Dim oBegining As msxml2.IXMLDOMNode
Dim oAttributes As msxml2.IXMLDOMNamedNodeMap
Dim oCountryName As msxml2.IXMLDOMNode
Dim oChildren As msxml2.IXMLDOMNodeList
Dim oChild As msxml2.IXMLDOMNode
Dim oNodeList As msxml2.IXMLDOMNodeList
Dim Startcell As Range
Dim temp As String
Dim temp2 As String
Dim Colno As Integer
Dim oCell As Range
Dim Path As String
Dim Counter As Integer
On Error GoTo Exitfun
Set oDoc = CreateObject("MSXML2.DOMDocument")
oDoc.async = False
oDoc.validateOnParse = False
' MsgBox oDoc.XML
Set oRoot = oDoc.documentElement
Set oNodeList = oDoc.getElementsByTagName("FSK:SecurityName") This works fine.
temp = oNodeList.Item(0).childNodes.Item(0).Text
Set Startcell = ActiveCell
Counter = 0 ' to count columns
For Each oCell In Worksheets("Instructions - Introduction").Range("G1:G21")
Path = oCell.Value
Set oChildren = oDoc.selectNodes(Path) This doesn't work sometimes.
Startcell.Offset(0, Counter).Value = oChildren.Length
Counter = Counter + 1
Exitfun: MsgBox "Error occured" & Counter
