[opencms-dev] Checking a xml element value

[lists at rueth.info]

Hi,

the cms:contentcheck tag allows to check for the presence of a xml
element, e.g. <cms:contentcheck ifexists="TableOfContents">. I have an
element TableOfContents of type CmsXmlBoolean. What I need is to check
the _value_ of the element (true or false), not its presence (it's
always there!). Is there any way how to achieve this using the
opencms.tld tag library?

Thanks and regards
Ulrich
