Java EE (Java Enterprise Edition) General Discussion

Hello,


I am new to xsl. I know how to check if an attribute exists:

<xsl:if test="@attribute">
....

<xsl:if>

but how could I check if an attribute does not exist?

I tried this:

<xsl:if test="not(@attribute)">
....

<xsl:if>

That did not work at all.

Appreciate any help.
