[Corpora-List] XML parsers vs regex

[Alberto Simões]

Dear Matías,

It depends a lot on the type of the process you are trying to perform.
If you want to search for a specific expression, regexp might be fast 
enough.

If you want to use the XML structure (for example, only match on a 
specific element type, or if some XML structure is present), the use of 
an XML parser might help.

Also note that for processing big XML files the use of a common XML 
DOM-oriented parser might be take too much memory. So, in some 
situations it would be relevant to choose the type of the XML parser as 
well (DOM vs SAX).

Hope this helps,
Best,
Alberto
