I'm going to try to insert your component in the main source.

But what are your problems exactly ? 

You must:

Create a Makefile.am file in each directory and subdirectory:
./src/lib/xml
./src/lib/xml/libxml
./src/lib/xml/libxml/rpc

Adds a call to GB_COMPONENT() macro for each component in configure.in.

NEVER use subdirectory includes like #include <libxml/tree.h>, but #include 
<tree.h> instead. The GB_COMPONENT macro will find the correct path.

NEVER use include paths and linker flags directly in the Makefile.am files, 
but use the variables declared by GB_COMPONENT.

The GB_COMPONENT macro for gb.xml.libxml looks like the GB_COMPONENT macro for 
SDL library, something like that:

GB_COMPONENT(
  libxml,
  LIBXML,
  [libxml-based XML parser component],
  [GB_FIND(parser.h, /usr/local /usr, include/libxml/libxml* include/libxml* 
include)],
  [GB_FIND(libxml2.$SHLIBEXT, /usr/local /usr, lib)],
  [$C_LIB $THREAD_LIB -lxml2 -lxslt -lz -lm]
  [$THREAD_INC])
  
I didn't test it yet, so maybe there are errors... :-/

Don't forget to tell AC_OUTPUT() to generate the makefile in configure.in.

A remark: do you have to include libxslt in the xml component ? Can't you make 
another component for libxslt ? I say that because I think libxslt should be 
a heavy library, so having to link to it just for reading xml files may not 
be a good idea.

As soon as I succeed in compiling your component, I will send my configure.in 
and Makefile.am files.
