XML Elves

I got a problem with size could someone help!

// ParseXML approach
// this is the working version, but limits us to SVG files smaller than 512K
// m_svgDoc is a CSVGDocument
// m_spSVGControl is an ATL smart pointer to the Adobe SVG Control's COM interface
// the Adobe SVG Control has already been created

m_svgDoc = m_spSVGControl->getSVGDocument(); CSVGWindow svgwnd = m_spSVGControl->Getwindow();

// szFile Buf is a pointer to a string contatining the contents read from an SVG file

CDOMNode node = svgwnd.parseXML( szFileBuf, m_svgDoc );

//
// ParseXML() causes a stack overflow when the SVG file is larger than about 512K
//

m_svgDoc.appendChild( node );

// m_RootElem is a CSVGSVGElement
// it is used to access and manipulate the top level element in the SVG document

m_RootElem = m_svgDoc.getRootElement();
