Hi, I need to get some values from a number of xml sources that have default namespaces. I've implemented the code from the sample SimplXPathAPI and got this to work if I removed the default namespaces but, if I leave them in, selectSingleNode returns NULL. I was able to remove the namespaces for my test data (or add prefixes), but unfortunately I will not be able to do this with the real data. I've done an exhaustive search of the xalan-c forums and the internet in general for the past several days and I've come up with a few things but I don't think I'm heading in the right direction any longer. I've implemented a PrefixResolver derivative (myPrefixResolver) and I'm passing an instance of that into the XPathEvaluator, so the XPath implementation can map the namespace prefix to the proper namespace URI. The problem is that I'm having trouble mapping the prefix to the namespace.
Optimally I would like to have a function in my PrefixResolver derivative that takes a prefix and a uri and adds it to my namespace. I've come up with the following (and many other variations) but it crashes when I try to set the node value. void myPrefixResolver::setPrefix(const XalanDOMString& prefix, const XalanDOMString& uri) { AttributeVectorType myVector(XalanMemMgrs::getDefaultXercesMemMgr(), 1); myVector.front()->setNodeValue(uri); m_namespaces.insert(&prefix, myVector); } I've tried many things including tying to clone an existing XalanNode and creating my vector this way. I haven't deviated much from the way XalanDocumentPrefixResolver derived from PrefixResolver. I am a bit desperate at this point because I have a very tight schedule and I thought this part would be the easy part. Any help that can be proffered would be extremely appreciated!
