[RESOLVED] Reading XML File

I'm fairly new at the whole XML thing, but I am trying to write some code that will give me data from an XML file.

Here's my issue. I have a file with multiple levels, and the data I want is 7-8 levels deep.

In the following XML file, I would like to return each <station> node, it's id attribute, and all of it's child-node data.

Code:

---

This file is a small part of a larger file (the Zap2It TV Listings Download), but I'm using this chunk to get some help.

I would like to use SelectNodes with XPath query language, but I'm having some trouble wrapping my head around it.

Any help would be much appreciated with an example specific to the XML I posted above.

Thank You,
Imp

add a reference to the Microsoft XML vX.0...

ok.. testing it I cant get it to work..
I did something similar and this worked... maybe its because the file isnt complete or the xsl (or whatever it is is missing?)
either way the xml load showed nothing..... odd

VB Code:

Private Sub Form_Load()
    Dim xmlDoc As New DOMDocument
    Dim N1 As Object
 
    
    xmlDoc.Load ("C:\test.xml")
    Debug.Print xmlDoc.xml
    For Each N1 In xmlDoc.getElementsByTagName("station")
        Debug.Print N1.id
        Debug.Print N1.getElementsByTagName("callSign").Text
        Debug.Print N1.getElementsByTagName("name").Text
        Debug.Print N1.getElementsByTagName("affiliate").Text
    Next
            
End Sub

I fixed the XML. There was an extra <station> tag without closure in there.

That is odd. I messed around with your code and got the same thing. Wonder why it won't load?

Can anyone help with this issue?

Thanks

is there xsl file?

I cant even get it to load in IE?

Fixed another issue in the XML file. There was a loose & in the first station name: A & E.

I added "amp;" after the & symbol and the app was able to read the xml file.

Imp

yep good catch.. this should get you started

VB Code:

Private Sub Form_Load()
    Dim xmlDoc As New DOMDocument
    Dim N1 As Object
    Dim N2 As Object
    
    xmlDoc.Load ("C:\test.xml")
    For Each N1 In xmlDoc.getElementsByTagName("station")
        Debug.Print N1.Text
        For Each N2 In N1.getElementsByTagName("callSign")
            Debug.Print N2.Text
        Next
        For Each N2 In N1.getElementsByTagName("name")
            Debug.Print N2.Text
        Next
        For Each N2 In N1.getElementsByTagName("affiliate")
            Debug.Print N2.Text
        Next
    Next
    
End Sub

Works great!, Thanks.

Yeah, I know it says "Resolved," and it was... but it isn't! The original request was to use SelectNodes and XPath. The answer was using the DOM Object methods. Which works for this situation, but what happens if you have multiple namespaces? And, where's the SelectNodes in the "answer?"

I've spent almost a week with the same question. There's, like, NOTHING online that's helpful. But, I found something that works, and it seems to actually answer the question. Here it is, using the example data supplied in the original request...

Code:

---

Option Explicit

Sub Main()

    Dim sDataPath As String
        sDataPath = "C:\_tmp\"
    Dim sXmlDocRadio As String
        sXmlDocRadio = "stations.xml"
   
    Dim oXmlDoc As New DOMDocument30
    Dim oStationsAxes As IXMLDOMNodeList    ' a Collection of Station entries
    Dim oStationNode As IXMLDOMNode        ' a single station
       
        oXmlDoc.async = False
        oXmlDoc.validateOnParse = False
        oXmlDoc.resolveExternals = False
        oXmlDoc.preserveWhiteSpace = True
        oXmlDoc.setProperty "SelectionLanguage", _
                            "XPath"
        oXmlDoc.setProperty "SelectionNamespaces", _
                            "xmlns:TMSWebServices='urn:TMSWebServices'"

    If oXmlDoc.Load(sDataPath & sXmlDocRadio) = False Then
        MsgBox "Failed to load xml data from file."
        Exit Sub
    End If
   
    ' E.G. we want all the stations, using XPath:
    Set oStationsAxes = _
        oXmlDoc.selectNodes("//TMSWebServices:stations/TMSWebServices:station")
    ' You could then iterate through these, but we'll skip it for now!
    ' It's just an example you can play with later.
    ' When you look at this obj in your locals window, look under children,
    ' and then item(n).ChildNodes.item(evenNumbers). I'll stop now!
   
    For Each oStationNode In _
            oXmlDoc.selectNodes("//TMSWebServices:stations/TMSWebServices:station")
   
        Debug.Print "Station ID: " _
                    & oStationNode.selectSingleNode("@id").Text
                   
        Debug.Print vbTab & "Callsign: " _
                    & oStationNode.selectSingleNode("TMSWebServices:callSign").Text
                   
        Debug.Print vbTab & "Name: " _
                    & oStationNode.selectSingleNode("TMSWebServices:name").Text
        Debug.Print vbTab & "Affiliate: " _
                    & oStationNode.selectSingleNode("TMSWebServices:affiliate").Text _
                    & vbCrLf
                   
    Next oStationNode
   
    Set oStationNode = Nothing
    Set oStationsAxes = Nothing
    Set oXmlDoc = Nothing

End Sub

In my work, I use TestPartner from Compuware to test applications. Test data sometimes comes from XML sources. I obviously need to find SOME way of processing the data. Most examples you can find online these days uses This.NET and That.NET, but VBA isn't .NET in TestPartner, and VB6 examples are getting hard to find! And the ones you CAN find, use very simple XML documents.

Enjoy! And, sorry for the intrusion!
