How to use method returned values in <xsl:if> condition

Hi,
I would like to use a java method's return values as operand in a <xsl:if> condition. What is the syntax for it?

When I use this
<xsl:if test="{$java:name($veh)} ='project'"> or
<xsl:if test="{java:name($veh)} ='project'"> I get exceptions.

Is there any way to avoid using temporary variable to store method returned value?

The syntax for calling out to Java depends on which XSLT processor you are using.

However, the test attribute of xsl:if should never include curly braces: it's an XPath expression, not an attribute value template. So it will be something like

Code:

<xsl:if test="java:method(a,b,c) = 'xyz'">
  ...
</xsl:if>

Thanks Michael,

Worked like a charm. I used the curly brackets because I read in the book that there is a restriction in XML that we cannot have an angle bracketed markup code in an attribute. But didn't know that I can call the method directly.
