In bibword xlst how to check for a null element

Dec 8, 2014 at 10:16 PM
How can I check if author is null. If it is I need to show title

If it has data I need it not to show anything

Obviously a test and an if statement are involved but where ?

BibWord uses { and } to allow for conditions. For more information and some examples, see the documentation . Make sure to check the example on volume, issue, and pages as it shows how complex you can go.

Thanks Yves I had already checked the volume,issue and pages section but can not figure a method which does the following

if author = is not NULL then display nothing
if author = NULL then display TITLE

This is a command that nearly works {%author|Title%}
However if author exists it display the author, I dont want it to ever display the author.
I want it to display the title if author does not exist

The programming I need is something like this:-

{<xsl:if test='Author=NULL' > {%Title%} </xsl:if>}

I think I understand what you are looking for. There is a trick you could use. You could create a format style for authors which produces no output. Then you could use {%Author:15|Title%} where 15 is the id of the contributor formatting you defined to output nothing.
