Since I struggled with this for a bit.... The following function
has two sections, one detailed out step by step (and also #if'd out
of existence) and a briefer version.
The dtd would be: <!ELEMENT p_sTag (#PCDATA)>
One question -- does Xerces distinguish between #PCDATA and CDATA?
The code below is reading CDATA. Is there a way to read #PCDATA?
//
// Reads an integer from the document. The enclosing tags must be p_sTag.
//
void ReadIntWithTag( DOM_Document & doc_, int & iValue, const string & p_sTag )
{
#if 0
// Get a DOM_NodeList of elements tagged p_sTag
DOM_NodeList cElem = doc_.getElementsByTagName(DOMString(p_sTag.c_str()));
// Get the first (which should be the only) one
DOM_Node cNode = cElem.item(0);
// Get a DOM_NodeList of its children
DOM_NodeList child = cNode.getChildNodes();
// Get the first (which should be the only) DOM_CDATASection
DOM_CDATASection cdata = ( const DOM_CDATASection & ) child.item(0);
// Get the data contained therein and convert it to a string.
string s ( cdata.getData().transcode() );
iValue = atoi( s.c_str() );
#endif // #if 0
// We don't need to be so verbose as above...
DOM_Node cNode = doc_.getElementsByTagName(DOMString(p_sTag.c_str())).item(0);
DOM_CDATASection cdata = ( const DOM_CDATASection & )
(cNode.getChildNodes().item(0));
iValue = atoi( cdata.getData().transcode() );
}
Thanks in advance,
