RE: String comparison

2003-10-13 09:01:10
Hi,

I am trying to comparing to see is a string is null,

There is no concept of "null" in XPath or XSLT.

I have a param named userid, i want to check to see if
'$userid' is not null.

I tried <xsl:if test="$userid!=''>, this does'nt seem
to help.

See <http://www.w3.org/TR/xpath#booleans> how comparisons work in XPath.

Anyhow, you can just use

  <xsl:if test="$userid">

Cheers,
