cvs commit: jakarta-commons-sandbox/jelly/src/java/org/apache/commons/jelly/tags/validate AssertValidTag.java
jstrachan 2002/08/15 00:55:46
Added: jelly/src/java/org/apache/commons/jelly/tags/validate
AssertValidTag.java
Log:
Added an <assertValid> tag which can be used in JellyUnit scripts to assert that a section of XML is valid according to some XML Schema, RelaxNG, Relax or TREX.
DTDs should work too, as MSV supports that too I think, but isn't quite working yet.
