I know that this question has been answered
somewhere before, but I simply cannot seem to hunt down a definitive answer and
all pointers lead back to this list. So, I apologize in advance for
the repetition.
I'm relatively new to SAX, but not-quite-so-new to
XML,DOM and XSLT. My task is to take a large XML file with multiple
occurences of a specific kind of element. I need to build an index that
lets me retrieve instances of that element from the file (at a later date) very
quickly.
My thought for this was to use the locator in a SAX
parser to identify the location of the start of the element tag in the file,
record that location persistently and then use the persistent location later on
to get my element (and its contents) back quickly.
My questions are:
Is there a SAX implementation for which the locator
is known to be accurate? I noted somewhere (in the SAX specification?)
that the locator is kind of intended for debugging more than document
manipulation. (and if it is written in c++ that makes my life MUCH
easier)
Is there an easier way to do what I need to
do? For each file I look at the element-of-interest will
change. There may be multiple (and different) types of interesting
elements in a single file. I am working with static files that will not
change once I process them.
Any help greatly appreciated!
