hi,
I am using the xerces-c API for c++ to read an XML document. But when i try
to read it is not able to read the whole document, it contains 153 elements
of type row, but when parsed using the functions, it is able to identify
only 62 of them(first 62). How come this happen?
I am attaching the code i am using to parse through the file and the
corresponding xml file.
regards
Jinesh K J
P.S: the XML appears to be of size more than 100kb. Thus i can't attach the
XML file. Sorry for that.
