Hi, I'm still having problems with setting up catalog files. I have created a catalog file to link to relative paths to the DTDs. When I try to validate the catalog file I get this error: http://www.w3.org/TR/xmlschema-1/#cvc-elt E cvc-elt.1: Cannot find the declaration of element 'catalog'. anzliccatalog.xml file:/E:/downloads/anzliccatalog.xml 6:1 I have changed the entry in the options => preferences => XML => XML Catalog to point to the anzliccatalog.xml as follows: file:/E:/downloads/anzliccatalog.xml The catalog file looks like this: <?xml version="1.0"?> <!DOCTYPE catalog PUBLIC "-//OASIS//DTD Entity Resolution XML Catalog V1.0//EN" "http://www.oasis-open.org/committees/entity/release/1.0/catalog.dtd"> <catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog" prefer="public"> <public publicId="-//ANZLIC//DTD ANZMETA 1.3//EN" uri="./sgml/anzmeta-1.3.dtd"/> <public publicId="ISO 8879-1986//ENTITIES Added Latin 1//EN//XML" uri="./sgml/ISOlat1.pen"/> <public publicId="ISO 9573-15:1993//ENTITIES Greek Letters//EN//XML" uri="./sgml/ISOgrk1.pen"/> <public publicId="ISO 8879:1986//ENTITIES Publishing//EN//XML" uri="./sgml/ISOpub.pen"/> <public publicId="ISO 8879:1986//ENTITIES General Technical//EN//XML" uri="./sgml/ISOtech.pen"/> <public publicId="ISO 8879:1986//ENTITIES Numeric and Special Graphic//EN//XML" uri="./sgml/ISOnum.pen"/> <public publicId="ISO 8879:1986//ENTITIES Diacritical Marks//EN//XML" uri="./sgml/ISOdia.pen"/> <public publicId="ISO 8879:1986//ENTITIES Added Latin 1//EN//XML" uri="./sgml/ISOlat1.pen"/> <!-- XHTML Stuff --> <public publicId="-//W3C//DTD XHTML 1.0 Strict//EN" uri="./sgml/xhtml1/DTD/xhtml1-strict.dtd"/> <public publicId="-//W3C//DTD XHTML 1.0 Transitional//EN" uri="./sgml/xhtml1/DTD/xhtml1-transitional.dtd"/> <public publicId="-//W3C//DTD XHTML 1.0 Frameset//EN" uri="./sgml/xhtml1/DTD/xhtml1-frameset.dtd"/> <public publicId="-//W3C//ENTITIES Latin 1 for XHTML//EN" uri="./sgml/xhtml1/DTD/xhtml1-lat1.ent"/> <public publicId="-//W3C//ENTITIES Symbols for XHTML//EN" uri="./sgml/xhtml1/DTD/xhtml1-symbol.ent"/> <public publicId="-//W3C//ENTITIES Special for XHTML//EN" uri="./sgml/xhtml1/DTD/xhtml1-special.ent"/> <!-- Document Type Definitions --> <public publicId="-//ANZLIC//DTD ANZMETA 1.3//EN" uri="./sgml/anzmeta/anzmeta-1.3.dtd"/> <public publicId="-//ANZLIC//DTD ANZMETA 1.2//EN" uri="./sgml/anzmeta/anzmeta-1.2.dtd"/> <public publicId="-//ANZLIC//DTD ANZMETA 1.1//EN" uri="./sgml/anzmeta/anzmeta-1.1.dtd"/> <public publicId="-//IndexGeo//DTD ANZMETA Resource 1.1//EN" uri="./sgml/indexgeo_resource.dtd"/> <public publicId="-//ANZLIC//DTD QSIIS 1.3//EN" uri="./sgml/qsiis-1.3.dtd"/> <public publicId="-//QSIIS//DTD QSIIS 1.3//EN" uri="./sgml/qsiis-1.3.dtd"/> <public publicId="-//NSW NRIMS//DTD ANZMETA NSW NRIMS Page 1 v1.0//EN" uri="./sgml/anzmeta-nswnrims-1-v10.dtd"/> </catalog> I have even downloaded the catalog.dtd file and it doesn't validate. Thanks in advance for any help that you can provide. John
