    Re: how to populate listview with this file

    Your question is regarding a listview, yet your sample code is for a treeveiw.

    If you spend some time learning how to use DOM to parse XML data, I think you could dramatically improve your ability to extract the data easier

    Re: how to populate listview with this file

    I can't tell how many of these questions are headed down the rabbit hole of trying to use controls in place of data structures. There doesn't seem to be any reason to display the information and there isn't any user interaction with it.

    Re: how to populate listview with this file

    Your XPath query is incorrect: "rom name"?
    Look at your previous thread where I helped you parse XML

    Re: how to populate listview with this file

    Using your exact code and the file you posted in #1 above, I get 3 games: 1942, 1942a, 1942b

    Whenever something is not working, you should explain in detail what you are expecting and any errors you are getting. If you are using On Error Resume Next, then don't do that -- you'll hide errors that could be telling you what is wrong.

    am trying to learn more about how to use this in depth.
    Code:
    ("game[rom[@name='03k_sb-8.bin']]")
    List1.AddItem xmlElement.getAttribute("name")
    for the sake of learning i want to extract all
    <rom name="41_09.rom" 41_09.rom strings in red area and load it up in treeview with parant rom title?.
    once i get the hang of it i can step forward test more my self am just stuck at this
    Code:
    ("game[rom[@rom name=]]")
    List1.AddItem xmlElement.getAttribute("name")
    i just want to learn how to pull them data out using xml method,xml seems very fast and i like it am just learning still.


    ok update i finally messed about did this and extracted all titles

    Code:
    Private Sub Command4_Click()
    List1.Clear
    Dim myXMLfile As DOMDocument60
        Dim xmlElement As IXMLDOMElement
        Dim xmlNodes As IXMLDOMNodeList
        Dim x As Long
    
        Set myXMLfile = New DOMDocument60
        myXMLfile.setProperty "ProhibitDTD", False
        myXMLfile.validateOnParse = False
     myXMLfile.Load "C:\Users\parry\Desktop\listview rom\MAME 0.37b5.dat"
    
    
        Set xmlNodes = myXMLfile.documentElement.selectNodes("game")
        For x = 0 To xmlNodes.length - 1
      
            Set xmlElement = xmlNodes(x)
           ' Debug.Print xmlElement.getAttribute("name")
            
            List1.AddItem xmlElement.getAttribute("name") '& ".zip"
            Next

    Re: how to populate listview with this file

    Open that dat file...

    game[rom[@name='03k_sb-8.bin']]

    the [ ] above are like parentheses
    game :: only look at 1st child elements where its element is <game [optional attributes]>
    rom :: only look at child elements of <game> where child name is <rom [optional attributes]>
    @name :: only look for attributes of <game><rom> where attribute name is "name" and value is: 03k_sb-8.bin
    the @ symbol means: attribute

    so, only these elements will be returned, if any
    <game [optional attributes]> having child elements like: <rom name="03k_sb-8.bin" [other optional attributes]>

    Look at sites that have tutorials for: XPath queries

    can you post just example code of this line.
    Code:
    ("game[rom[@name='03k_sb-8.bin']]")
    List1.AddItem xmlElement.getAttribute("name")
    how you will tell the code to extract that rom name= only

    ok this also pulls names again

    Code:
    Private Sub Command5_Click()
    List1.Clear
    Dim myXMLfile As DOMDocument60
        Dim xmlElement As IXMLDOMElement
        Dim xmlNodes As IXMLDOMNodeList
        Dim x As Long
    
        Set myXMLfile = New DOMDocument60
        myXMLfile.setProperty "ProhibitDTD", False
        myXMLfile.validateOnParse = False
     myXMLfile.Load "C:\Users\parry\Desktop\listview rom\MAME 0.37b5.dat"
    
        Set xmlNodes = myXMLfile.documentElement.selectNodes("game[rom[@rom]]")
        For x = 0 To xmlNodes.length - 1
            Set xmlElement = xmlNodes(x)
            List1.AddItem xmlElement.getAttribute("name")
            Next
    End Sub
    am trying to get to extract the rom name secion trying.

    Re: how to populate listview with this file

    The rom name attribute value of each game element would be:

    ("game/rom")
    List1.AddItem xmlElement.getAttribute("name")

    Look at this example:
    Code:
    Private Sub Command4_Click()
    List1.Clear
    Dim myXMLfile As DOMDocument60
        Dim xmlElement As IXMLDOMElement
        Dim xmlNodes As IXMLDOMNodeList
        Dim xmlROMs As IXMLDOMNodeList
        Dim x As Long, r As Long
    
        Set myXMLfile = New DOMDocument60
        myXMLfile.setProperty "ProhibitDTD", False
        myXMLfile.validateOnParse = False

    thanks lavlope am not going to close this thread as i will be doing more test to learn from your code this is incredible.
    the way you done it is way different to code i posted.

    Re: how to populate listview with this file

    Don't both ListView and TreeView have a 32767 node limit anyway?

    I'd use SAX2 and the MSHFlexGrid for this sort of thing. Assuming of course that it makes sense to list everything, which I doubt.

    XML DOMs are pretty bloated to begin with and don't do that well for large documents. Then when you add the scripter's tool XPath to the mix... things gear down pretty quickly to a crawl.

    There's a good reason we have SAX2, and even the DOM uses it internally to do its parsing.
