Hi Ramon,
if you already tried XPath, you can use it also with Xerces 3.x
XercesDOMParser parser;
parser.parse("c:\\simple-sample.xml");
DOMDocument *document = parser.getDocument();
XMLCh xpathStr[100];
XMLString::transcode("/line-segments/vertical/distance",xpathStr,99);
DOMXPathResult* result= document->evaluate(xpathStr,
document->getDocumentElement(), NULL,
DOMXPathResult::ORDERED_NODE_SNAPSHOT_TYPE, NULL);
int count = result->getSnapshotLength();
for(int i=0;i<count;i++) {
result->snapshotItem(i); // this select the node for the
getNodeValue call
DOMNode* item = result->getNodeValue();
// do something with the item->getTextContent()
}
result->release();

Greetings and Happy New Year to all,
This is my second attempt to learn and embrace Xerces-C, I hope it will
be a successful one this time. It is a New Year resolution. ;-)
Some time ago I incorporated Xerces into my applications, but the code I
wrote seemed a very complex way to achieve simple results. I then
decided that all that work and frustration was not worth the trouble,
and switched to Java+XPath. It works great, but some of my XML-related
apps must be written in C/C++.
To further complicate matters, the hard disk where I had all my Xerces
code died at the worst possible time.
I would like to start with a fresh look at Xerces again. Could any of
you nice fellows provide a simple, tutorial-like code to traverse a tree
like the one attached? All what is needed are those numerical values. I
am sure I can write some sort of code, but like I said I believe I am
failing to write it in the best/simplest way.
TIA,
-Ramon
