Reading xml through Qt

I am new to Qt and XML . Please help me on solving this . I shall be greatful to you .
Here is my XML file format

Code:

---

< SiteSpecific>
 
< SitesList>LocA;LocB;LocC< /SitesList>
 
< LocA>
 
      < MaterialList>Material_A;Material_B</MaterialList>
 
      <Material Name="Material_A">
 
      <TemperatureList>-65;70;300;400;1000</TemperatureList>
 
    <Density Value="0.286"/>
 
    <PoissonRatio Value="0.27"/>
 
        <Property tempid="01" temp="-65">
            <Modulus Value="32.77E+6"/>
            <Alpha Value="8.15E-6"/>
            <YieldStrength Value="33.90E+3"/>
        </Property>
 
        <Property tempid="02" temp="70">
            <Modulus Value="29.00E+6"/>
            <Alpha Value="8.55E-6"/>
            <YieldStrength Value="30.00E+3"/>
=       </Property>
 
        <Property tempid="03" temp="300">
            <Modulus Value="27.50E+6"/>
            <Alpha Value="9.26E-6"/>
            <YieldStrength Value="22.40E+3"/>
        </Property>
 
    </Material>
</LocA>
< LocB>
 
      < MaterialList>Material_C;Material_D</MaterialList>
 
      <Material Name="Material_C">
 
      <TemperatureList>-65;70;300;400;1000</TemperatureList>
 
    <Density Value="0.286"/>
 
    <PoissonRatio Value="0.27"/>
 
        <Property tempid="01" temp="-65">
            <Modulus Value="32.77E+6"/>
            <Alpha Value="8.15E-6"/>
            <YieldStrength Value="33.90E+3"/>
        </Property>
 
    <Material Name="Material_D">
 
      <TemperatureList>-65;70;300;400;1000</TemperatureList>
 
    <Density Value="0.286"/>
 
    <PoissonRatio Value="0.27"/>
 
        <Property tempid="01" temp="-65">
            <Modulus Value="32.77E+6"/>
            <Alpha Value="8.15E-6"/>
            <YieldStrength Value="33.90E+3"/>
        </Property>
 
    </Material>
</LocB>

From the above file format i have to extract Materialist(e.g Material_A , Material_B , Material_C , Material_D) , Temperaturelist(e.g. -65,70,300,400,1000) and all the properties (Modulus , alpha and yieldstrength )based on tempid for LocA and LocB .

What is the problem you are having?

I am not going to read the XML file at once . The tag name will be given to the programme during runtime . Please suggest for this kind fo requirement which way i should go , QXmlStreamReader or
QDomDocument .

Please suggest some coding concept based on it ..
Thanks in adv .

Both approaches are fine. QDomDocument is easier to use for beginners, QXmlStreamReader is more versatile.
