    Default XML Getting attributes of a specific value

    I have an XML document in this format:

    Qt Code:
    1. <h1 Name="foo">
    2. <h2 Name="goo" h2ID="0">
    3. ...
    4. </h2>
    5. <h2 Name="hoo" h2ID="1">
    6. ...
    7. </h2>
    8. <h2 Name="joo" h2ID="2">
    9. ...
    10. </h2>
    11. </h1>
    To copy to clipboard, switch view to plain text mode 

    I want to create a function that lets the user input the h2ID value, and then return the h2 Name associated with that value. How would I go about doing that?

    So far I have:

    Qt Code:
    1. QString Program::getH2Name(int h2ID)
    2. {
    3. QDomElement root = domDocument.documentElement();
    4. QDomElement child1 = root.firstChildElement("h1");
    5. QDomElement child2 = child1.firstChildElement();
    6. if (child2.tagName() == "h2") {
    7. return child2.attribute("Name");
    8. }
    9. }
    To copy to clipboard, switch view to plain text mode 

    This will only return the Name of the first h2 element: "goo". How do I get a specific h2 element using the h2ID? Thanks.

    Default Re: XML Getting attributes of a specific value

    you can use QDomElement::elementsByTagName() and iterate over the returned list, till you get your id or use XQuery (->QXmlQuery).
