& XSLT Hi

  Sorry for newbie question but i cannot figure out how to resolve 
following problems. There are references to  the dtd files at the 
beginning of xml files:

1)  If there is external references to public dts's like 
'http://www.w3.org/TR/REC-SMIL/SMIL10.dtd' the parser (XML::SPath) 
sometimes dies due to network or access error to given url.

2) Sometimes there is only reference to SMIL10.dtd with no other 
information and the parser also fails in this case.


  I have read  a mechanism called catalogs and made a file /etc/xml/catalog 
but there is something missing, that file is not even read during xml 
parsing.

  Any pointers to start with?
