If you need a pure Perl XML parser implementation you might want to take a look at Ryan Eatmon's work in XML::Stream::Parser. I was using his parser for a while because of that pure Perl requirement that I promptly ignored later because of the issues regarding error handling.

Last time I used X::S::P it did not handle malformated XML at all. And in fact, it would promptly screw up its internal state into an ever growing memory leak. Plus, it is also very /slow/. Even though he makes use of lower level string manipulation and character by character comparisons, it is still extremely slow compared to other C-based parsers (Expat, aka XML::Parser, etc)

So. With those caveats, it is an acceptable module to use when you have a pure Perl requirement and you /know/ that the XML you will be parsing doesn't have any funkiness in it.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
