The overhead of sax/dom parser is large. So is it
> reasonable to use regular expressions to parse xml?
NO, absolutely not. XML cannot be parsed correctly using regular expressions
because it is not a regular language. Parsing it incorrectly may be an
option for you, but is almost certainly a bad idea in the long term. Even if
it were an option, the overhead would be much higher than using a SAX
parser.
>Do jaxb or jaxp fit in my application?
JAXP offers an API to SAX and DOM parsers, so it's complementary to the
approach suggested.
JAXB is an alternative: it will have similar performance costs to DOM
parsing but (depending on the data structure) may be an easier way of
writing the application.
