Which is a faster parser for XML? [closed]

Question

I am trying to parse a simple file, and I want to know between:

• XML::Simple
• XML::Smart
• LibXML

which one is faster?

Answer 1

XML::LibXML is the fastest, see the benchmarks at Ways to Rome.

It may or may not matter for a "simple file" (which I assume would mean that it's not too big).

Answer 2

There's also XML::Fast which seems to be a pretty serious contender. XML::Simple can use XML::LibXML under the hood, but I'm still seeing it as the major CPU drain in my CalDAV testing right now.

It's worth giving it a try if speed is a major consideration for you.
