[vikuseth]

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

< SiteSpecific>
 
< SitesList>LocA;LocB;LocC< /SitesList>
 
< LocA>
 
      < MaterialList>Material_A;Material_B</MaterialList>
 
      <Material Name="Material_A">

    <Density Value="0.286"/>
 
    <PoissonRatio Value="0.27"/>
 
        <Property tempid="01" temp="-65">

    </Material>
</LocB>

To copy to clipboard, switch view to plain text mode 

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?

[vikuseth]

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 .

[wysota]

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