Hello all,

I have a markup, which looks like below:

<author primaryauthor="no" corresponding="no" seq="2">
<name><givenname>Julia</givenname><surname>Laker</surname></name>
</author>

All I am trying to check whether <givenname> contains "." or not, if it does
take whole <givenname> string otherwise get the first character. Below is
what I have defined, which was working perfect earlier with "1.0" version,
but doesn't seems to be working with version 2.0. I tried to modify the
xpath with 		<xsl:when
test="./author[1]/name/givenname[contains(string(), '.')]">, which do not me
error but also do not produce the desired output.

Stylesheet
============

	<xsl:choose>
		<xsl:when
test="./author[1]/name/givenname/contains(string(), '.')">
		<xsl:value-of select="./author[1]/name/givenname/string()"/>
		</xsl:when>
		<xsl:otherwise>
		<xsl:value-of
select="./author[1]/name/givenname/substring(string(), 1, 1)"/>
		<xsl:text>.</xsl:text>
		</xsl:otherwise>
	</xsl:choose>

Can somebody guide me.


Best,

Pankaj Chaturvedi
