OK I am relatively new to python and I know this is kind of a general
python question but I haven't found an answer any where else. I know you
can chain filters by calling nextfilter.startElement(..) and so on. But
what if you want sequential filters to modify information that might
have been added to the document by a previous filter? I assume you need
to parse for each filter but it doesn't matter. What I cannot figure out
is how to get the results of the parse into a string that I can pass on
to a second parse with a different filter. I hope I am being clear
enough here. I want to parse a file and have the result put into a
string that I can parse a second time using a different filter. Any
suggestions?
If I understand you, you may want to use some variation on
xml.sax.XMLGenerator you might find the following useful:

Well, I started off with your example "Tip: SAX filters for flexible
processing" on IBM's developerworks and have reviewed many of your other
articles. I under stand how most of it works including XMLGenerator. The
problem I have is more general, a lack of Python knowledge. When I try
using XMLGenerator, the result goes to standard output, my questions is
how to get it to go into a string(variable) within the program that can
be passed on to a second parser instance. I assume I pass a reference to
a global variable to the filter. I am missing how to get XMLGenerator
to write to that variable. Am I missing something with XMLGenerator? Is
there a way to get the output from the XMLGenerator instance itself?
Hopefully I am being more clear this time.
Thank You,
J. Lujan
