[Corpora-List] XML parsers vs regex

[Dave Graff]

When it comes to handling specific subsets of content based on the markup structure and/or attribute values of certain tags, using a parser - and particularly a tool that supports XPath expressions - will give fully reliable results with the least amount of effort (given that you've taken the time to learn how to use XPath, which is probably easier, or at least no harder, than learning to use regexes).

Speaking from my own experience (in Perl and Ruby), it seems more often the case that using a parser tends to yield shorter scripts that are easier to maintain and adapt.
