Please help

[Vincent Richomme]

Hi,

I am trying to parse the following :
<?xml version="1.0" ?>
<resource version="0.1">
    <object class="CView" name="Default">
        <background fillmode="normal" LowColor="0x000000" HiColor="0x000000" />
       
        <object class="Static" name="ID_STATIC_1000">
            <id>1000</id>
            <pos>1,361</pos>
            <size>100,40</size>
            <bg fillmode="0" LowColor="0xc8d0d4" HiColor="0xc8d0d4" />
        </object>
        <object class="Static" name="ID_STATIC_1001">
            <id>1001</id>
            <pos>245,519</pos>
            <size>100,40</size>
            <bg fillmode="0" LowColor="0xcdcdcdcd" HiColor="0xcdcdcdcd" />
        </object>
    </object>
</resource>

So I am trying this :
// Load Xml
    bool bRet = doc.LoadFile( CMisc::GetAppPath() + _T("Borne.xui") );
    if (!bRet)
        return;

    // Go directly to  <object> section
    TiXmlHandle docHandle( &doc );
    TiXmlHandle resHandle = docHandle.
        FirstChild( _T("resource") ).
        FirstChild( _T("object") ).
        FirstChild( _T("object") );

    pXMLElement = resHandle.Element();
    while( pXMLElement ){
        CGUIElement* NewWidget = NULL;
       
        if( _tcsicmp(pXMLElement->Attribute( _T("class") ), "Static") == 0)
            NewWidget = new CGUIStatic( );
        //else if( _tcsicmp(pXMLElement->Attribute( _T("class") ), "Picture") == 0)
        //    NewWidget = new CGUIPicture( );

        // Go deeper
        pXMLElement = pXMLElement->FirstChild()->ToElement();
       
        while( pXMLElement ){

        strTmp = pXMLElement->Value();
        if( _tcsicmp(pXMLElement->Value(), _T("id"))  == 0){

            strTmp = pXMLElement->ToText()->Value(); // EXCEPTION ???

        }
       
        pXMLElement = pXMLElement->NextSiblingElement();
    }
        // move to the next control
        pXMLElement = pXMLElement->NextSiblingElement("object");
    }

The problem is to get text from <id>, <pos>, ...

I always have a NULL pointer everytime i call ToText() to get the id text for instance while I am sure there is some text.

What am I doing wrong ?

even when I try this simple thing it fais :

// Load Xml
    bool bRet = doc.LoadFile( CMisc::GetAppPath() + _T("Borne.xui") );
    if (!bRet)
        return;

    // Go directly to  <object> section
    TiXmlHandle docHandle( &doc );
    TiXmlHandle resHandle = docHandle.
        FirstChild( _T("resource") ).
        FirstChild( _T("object") ).
        FirstChild( _T("object") ).
        FirstChild( _T("id") );

    pXMLElement = resHandle.Element();
    TRACE( _T("<%s>\n"), pXMLElement->Value() );
    strTmp = pXMLElement->ToText()->Value();

Vincent,
You are missing one point at the end.
A text node is a child of an element.
So you need to write
strTmp=pXMLElement->FirstChild()->ToText()->Value()

But you'd better put some code to ensure there's a text child.
