Well yes and no. The getTextContent method is distributed with version
2.3. But it contains a bug. I hope that a committer has put the patch
into the nightly build by now.
If you are compiling Xerces yourself then it is a breeze to extend your
2.2 version to support getTextContent. Just put the following code in
DOMNodeImpl.h.
const XMLCh* getTextContent(XMLCh* pzBuffer, unsigned int&
rnBufferLength) const;
const XMLCh* getTextContent() const ;
And the following in DOMNodeImpl.cpp.
const XMLCh* DOMNodeImpl::getTextContent(XMLCh* pzBuffer, unsigned int&
rnBufferLength) const
{
unsigned int nRemainingBuffer = rnBufferLength;
rnBufferLength = 0;
if (pzBuffer)
*pzBuffer = 0;
DOMNode *thisNode = castToNode(this);
switch (thisNode->getNodeType()) {
case DOMNode::ELEMENT_NODE:
case DOMNode::ENTITY_NODE:
case DOMNode::ENTITY_REFERENCE_NODE:
case DOMNode::DOCUMENT_FRAGMENT_NODE:
{
DOMNode* current = thisNode->getFirstChild();
while (current != NULL) {
if (current->getNodeType() != DOMNode::COMMENT_NODE &&
current->getNodeType() !=
DOMNode::PROCESSING_INSTRUCTION_NODE)
{
if (pzBuffer) {
unsigned int nContentLength = nRemainingBuffer;
castToNodeImpl(current)->getTextContent(pzBuffer +
rnBufferLength, nContentLength);
rnBufferLength += nContentLength;
nRemainingBuffer -= nContentLength;
}
else {
unsigned int nContentLength = 0;
castToNodeImpl(current)->getTextContent(NULL,
nContentLength);
rnBufferLength += nContentLength;
}
}
current = current->getNextSibling();
}
}
break;
case DOMNode::ATTRIBUTE_NODE:
case DOMNode::TEXT_NODE:
case DOMNode::CDATA_SECTION_NODE:
case DOMNode::COMMENT_NODE:
case DOMNode::PROCESSING_INSTRUCTION_NODE:
{
const XMLCh* pzValue = thisNode->getNodeValue();
unsigned int nStrLen = XMLString::stringLen(pzValue);
if (pzBuffer) {
unsigned int nContentLength = (nRemainingBuffer >= nStrLen) ?
nStrLen : nRemainingBuffer;
XMLString::copyNString(pzBuffer + rnBufferLength, pzValue,
nContentLength);
rnBufferLength += nContentLength;
nRemainingBuffer -= nContentLength;
}
else {
rnBufferLength += nStrLen;
}
}
break;
}
return pzBuffer;
}
const XMLCh* DOMNodeImpl::getTextContent() const
{
unsigned int nStringLength = 0;
getTextContent(NULL, nStringLength);
XMLCh* pzBuffer = (XMLCh*)
((DOMDocumentImpl*)getOwnerDocument())->allocate((nStringLength+1) *
sizeof(XMLCh));
getTextContent(pzBuffer, nStringLength);
pzBuffer[nStringLength] = 0;
return pzBuffer;
}
