Parsing an XML file to populate a structure in C /C++

I have the following xml file which has attributes corresponding to a structure.

How do i read the content from the XML file and populate the coresponding values in the structure?Please see the XML file below.

<Struct>
<StructEntry name="presenceNotification">
    <Enum>PRESENCE_NOTIFICATION_UEMOBILITY_UPDATE</Enum>
</StructEntry>
<StructEntry name="ueDirectoryInfo">
    <Struct>  <!-- ueDirectoryInfo  -->
        <StructEntry name="acap_PresenceOptsMask">
            <Int>0</Int>
        </StructEntry>
        <StructEntry name="imsi">
            <Struct>
                <StructEntry name="length">
                   <Int>10</Int>
                </StructEntry>
                <StructEntry name="value">
                   <Sequence>
                       <Int>1</Int>

You can use a library (like tinyXML) to parse your XML file

---

You could try CodeSynthesis XSD:

an open-source, cross-platform W3C XML Schema to C++ data binding compiler.

To give you a taste of what it's capable of, given this XML file:

<contact>
  <name>John Doe</name>
  <email>j@doe.com</email>
  <phone>555 12345</phone>
</contact>

can produce the following C++ code (using generated classes with a corresponding XSD):

auto_ptr<Contact> c = contact ("c.xml");
cout << c->name () << ", "
     << c->email () << ", "
     << c->phone () << endl;

Basically it's a code generator that will generate the C++ classes and code to load the XML data into those classes.

Use a library such as http://msdn.microsoft.com/en-us/magazine/cc163436.aspx

You can have a look at Xerces. A an open source library for XML Parsing.
