Re: [xml] updating libxml2

  I have not updating libxml2 in quite a long time, so I had some
  questions about updating it:

1.       According to "xml2-config -version", I am at version 2.4.19.
Is this the libxml2 version I am using?

Probably yes. 2.4.19 is seven years old. Newest is 2.7.3.

If not, how do I retrieve that information?  It has been quite a few

milu colinux:~/xpg > xml2-config --version

milu colinux:~/xpg > xmllint --version

libxslt 10124 was compiled against libxml 20702

2.       What dangers should I be aware of, at a high level?  For
instance, should I backup my current libxml2 instance before doing it?

You don't need to do that if you install your new version from source
and compile with "--prefix=/usr/local/my-new-libxml2", or probably just

3.       I am thinking it will just overwrite my current libxml2.  Is
this correct?

Not necessarily, see #2.

4.       Will this include a new and improved version of xmllint?

You could take a look at the change log to find out. Or maybe just give
it a try.
