evaluate path to schema dynamically
Hi all,
I am using the SAX2XMLReader class for parsing a XML file. Now I am
searching for a possibility to implement the following feature:
the schema files are stored in one directory but there may be several
different versions (e.g. "schemaVersion1.xsd", schemaVersion2.xsd" ...). The
XML file "knows" to which schema it belongs to - as it is coded in the
xsi:noNamespaceSchemaLocation attribute - but the path to the directory is
given by the application.
At the moment I am using setProperty() to tell my parser where to look for
the corresponding schema files. But this method requires to set the full
path together with the name of the schema file. But my application should be
able to handle XML files of different versions by itself so that the user
doesn't have to specify the name of the schema file to look for.
Is there a possibility to only let the parser know where to look for the
schema file, the right version of the schema file (name given in the
noNamespaceSchemaLocation atribute) is then picked up by the parser itself?
Thanks for any help,
Bettina

Hi Bettina,
you can use an EntityResolver to have your program resolve the schema path
for the parser. Have a look at the Redirect sample.
