xslt - XPATH to display based on conditional value -

<chapter>     <concept>         <title>*********************</title>     .     .     </concept>      <sections>        <title>*******************</title>  </chapter> 

in above structure retrieve text <concept><title> or <sections><title>. i.e. using 1 xpath condition need value below conditions.

1) if <concept><title> not appeared <sections><title>. vice verso also..

2) both title available there want consider nearst node value. i.e. in above structure "<sections><title>" latest node.

you want "nearest" (first) of two:

(/*/*[self::concept or self::sections]/title)[1] 

if want "latest" (last) of them, use:

(/*/*[self::concept or self::sections]/title)[last()]

xslt - based verification:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform">  <xsl:output omit-xml-declaration="yes" indent="yes"/>   <xsl:template match="/">   <xsl:copy-of select=      "(/*/*[self::concept or self::sections]/title)[1]"/> ===============   <xsl:copy-of select=      "(/*/*[self::concept or self::sections]/title)[last()]"/>  </xsl:template> </xsl:stylesheet> 

when transformation applied on following xml document:

<chapter>     <concept>         <title>*********title 1************</title>     .     .     </concept>      <sections>        <title>**********title 2*********</title>     </sections>  </chapter> 

the 2 xpath expressions evaluated , results copied output:

<title>*********title 1************</title> =============== <title>**********title 2*********</title>
