get first element whose preceding

sunnykeerthi · May 5th, 2014, 02:02 PM

I've the below sample xml tree.

Code:

-root
  -para
   -page
   -footnum
  -para
   -footnum
  -para
   -footnum
  -para
   -page
   -footnum

I want to apply templates on the first footnum whose preceding is page. From inside the footnum template. here below para there will be even more nodesbut here i want to apply-template only to the first footnum followed by page,, whether it is in same para or different.

The code i tried is as below.

Code:

<xsl:if test="preceding::page[1]"> 
<xsl:apply-templates select="preceding::page[1]"/>
</xsl:if>

here it is applying templates for all the footnums. please let me know where am i going wrong.

Thanks

What you are actually testing there is if the current element has at least one page in the preceding axis.

To test if the first preceding element is a page element then test for:

preceding::*[1][self::page]

Hi samjudson,

Thanks for the reply, this is working fine for some but not everywhere. I want something like where the match goes to root and then to the pagenum and the following first sibling footnote.

Thanks

Giving you "something like" what you want is easy. Giving you exactly what you want requires a more precise statement of requirements.
