Subject RE: [C2] Accessing CLOBs as Documents
Date Thu, 18 Oct 2001 17:13:50 GMT
I have a similar application - but the clob is an xml fragment ( meaning
it doesn't have processing instruction tags ).  So I can use get-xml
instead of the get-ascii you use.  Then I can access data in the xml
fragment with the XSL stylesheet.
