How do I install the latest build of xmllint on OSX 10.7.5

Question

The problem is that I am trying to validate an xml file using xmllint. On my machine (OSX 10f.7.5) it says the xml is invalid. When a co-worker tries it on his machine, it says it is valid. I am not sure what version of OSX he is running but I do know that my version of xmllint is

$ xmllint --version
xmllint: using libxml version 20703

and his version is

$ xmllint --version
xmllint: using libxml version 20708

So the question is how do I build that version (or the latest version) on my machine?

Answer 1

It seems that the xmlstarlet package contains xmllint, so this should do the trick:

brew install xmlstarlet

I'm not sure how you would get a specific version though.
