I am parsing using the reader walker Api's. While walking the tree I need to
skip the subtree for a certain element, I tried to use the xmlTextReaderNext
API, however it is returning me an erroneous result, it returns me the child
node of the element whose subtree I want to skip.
This happens because in case of a preparsed document a different set of
Api's are called
if (reader->doc != NULL)
return(xmlTextReaderNextTree(reader)); ------> This API too should
effectively skip the sub-tree, but it does not.
ah, then it's a bug. i have tried to make sure the reader and the walker
work the same, but i think I didn't tried that extensively for extra
functionality like skipping part of the tree.
Can you see why xmlTextReaderNextTree doesn't work, it seems it should
do what is expected, i don't really see why not.
If however I create a reader using xmlReaderForMemory then the functionality
is fine, as it goes to the following part of the code in xmlTextReaderNext
ret = xmlTextReaderRead(reader);
if (ret != 1)
} while (reader->node != cur);
And returns the node after skipping the sub-tree.
yes that's the expected behaviour,
Is this a usage issue or a problem with the implementation of
xmlTextReaderNextTree Api, which is invoked in the case of pre-parsed
yes i think so,
