http://www.zend.com/php5/andi-book-excerpt.php says

"In PHP 5, all XML extensions have been rewritten to use the superb libxml2 XML toolkit"

But the official docs http://us4.php.net/manual/en/ref.xml.php
on XML extension say under the requirements section


" This extension uses expat, which can be found at
http://www.jclark.com/xml/expat.html."

There used to be some talk about "bundled libxml".
I couldn't find any bundled libxml2 in the PHP5 distribution.
Is ext/libxml2 it ?
.. or do I need to pick it up from xmlsoft.org ?

I would prefer to use libxml2 for all extensions really.

This is no longer correct.  It _can_ use expat, but by default it uses
an expat compat layer.

You do.  There was active discussion about a year and a half ago as to
whether to bundle it or not.  The decision was 'not'.  Search the
archives if you are interested in the various points.

Then you're in luck, because PHP5 does.

Unfortunately nobody from phpdoc had found the spare time to update the docs.
If you file a bug report at bugs.php.net (Documentation problem) it will be
adressed sooner or later, as somebody finds time.

Yes, you have it to pick up from xmlsoft.org

It's possible, read the output from ./configure --help ;-)
