I took a look at the headers on my system for comparison [RedHat... uh..
(6.0+6.1)/2], and in /usr/include/gnome-xml/tree.h from libxml-devel-1.7.3-1,
I find the following structure:

typedef struct xmlNode {
    ...
    struct xmlNode *childs;	/* parent->childs link */
    ...
}

I'm guessing this part of the code was originally written by a non-native
speaker of English? :)  If PHP4 is using 'children' instead of 'childs', then
this was probably changed in a later version of GNOME's libxml.  According to
the NEWS file, nothing older than libxml 2.0 beta is now supported.
Just checked RedHat 6.2 as well -- libxml-1.8.6-2 also lists 'childs' instead
of 'children'.  So it looks like this DOM XML support doesn't work with any
versions of libxml that RedHat ships.
