Update your install sources to include packman and guru, it might help some. On the opensuse 10.2 dvd it is listed in files list of rpm "expat-2.0.0-32.i586.rpm"
" compat-expat1 - XML Parser Toolkit
Expat is an XML 1.0 parser written in C. It aims to be fully conformant. It is currently not a validating XML processor. The current production version of expat can be downloaded from
ftp://ftp.jclark.com/pub/xml/expat.zip. The directory xmltok contains a low-level library for tokenizing XML. The interface is documented in xmltok/xmltok.h. The directory xmlparse contains an XML parser library that is built on top of the xmltok library. The interface is documented in xmlparse/xmlparse.h. The directory sample contains a simple example program using this interface. The directory sample/build.bat is a batch file to build the example using Visual C++. The directory xmlwf contains the xmlwf application, which uses the xmlparse library. The arguments to xmlwf are one or more files to check for well-formedness. An option -d dir can be specified. For each well-formed input file, the corresponding canonical XML is written to dir/f, where f is the filename (without any path) of the input file. A -x option causes references to external general entities to be processed. A -s option makes documents that are not stand-alone cause an error (a document is considered stand-alone if it is intrinsically stand-alone because it has no external subset and no references to parameter entities in the internal subset or it is declared as stand-alone in the XML declaration). "
VMware player also provides it.
Hope this helped
