Second, if the current node is element 'foo' and you have something like <foo> True <bar>Hi!</bar> <baz>123</baz> </foo> ...then the string value is \n True\n Hi!\n 123\n And finally, if your example is not accurate and you are actually testing something like <xsl:when test="/path/to/some/nodes = 'True'"> or <xsl:variable name="some_nodes" select="/path/to/some/nodes"/> <xsl:when test="$some_nodes = 'True'"> ...then the test will succeed as long as *any* of the 'nodes' elements have the string value 'True'. - Mike ____________________________________________________________________ Mike J.
