XML Parsing : JDOM or RegEx ? Which is faster ?

Hi,

A colleague of mine needs to develop an Eclipse plugin that has to parse multiple XML files to check for programming rules imposed by a client (for example, no xsl:for-each, or no namespaces declared but not used). There are about a 1000 files to be parsed regularly, each file containing about 300-400 lines.

We were wondering which solution was faster to do it. I'm thinking JDOM, and he's thinking RegEx.

Anyone can help us decide which is best ?

Thanks

Definitely not regexps. XML formats can change in ways that don't effect their content (in other words: that are invisible to XML-handling libraries), yet are significant to regexps. Such code becomes a maintenance nightmare quickly.

As to which parser to use (SAX, StAX, DOM, JDOM, dom4j, XOM, etc.), that's mostly a matter of preference. Is speed the only consideration?
