Hi Daniel and everybody in the list, First of all, thank you for your work on this powerful library !
I understand that, in order to perform a relative XPath search starting from a given XML node (that is, using an XPath string such as "element/@attr" to retrieve the attributes "attr" of the child nodes named "element" of a given tree node, be it "xmlNode") I have to do something like this: xmlNodePtr xmlNode; // my 'context' node const xmlChar* xpathExpr = BAD_CAST "element/@attr"; // Create xpath evaluation context xmlXPathContextPtr xpathCtx = xmlXPathNewContext(xmlNode->doc); // Set xpathCtx->node to the passed context node // before calling the XPath evaluation function, // and use a relative search xpathCtx->node = xmlNode; // ... do the xpath work, etc. etc. My application needs to be able to do that even if "xmlNode" does not belong to any DOM (that is, a subtree of nodes created by scratch). I tried to do this: // Create xpath evaluation context xpathCtx = xmlXPathNewContext(NULL); and it seems to be working properly. But I wonder, is that safe ? I tried with lots of different XPath strings on lots of different XML documents, but how can I tell my tests are exhaustive enough ? Unfortunately my PMs do not allow me to switch to the latest version of libxml2. We started using version 2.6.14. Thank you in advance for any help you can give me.
