[HELP] XSL silly question

Hi, I am a newbie in XML and XSL, and having the following XSL question.

The XML data:
<document>
<segment Id="A">
<type Id="A01">Blue</type>
<type Id="A02">Water</type>
</segment>
<segment Id="A">
<type Id="A01">Green</type>
<type Id="A02">Grass</type>
</segment>
</document>

Problem: I would like to select the value of "A02" when the "A01" is Green. How can it be implemented in XSL? Any help will be much appreciated!!

Hello,
please try following xsl for your problem....

<?xml version="1.0"?>
<xsl:stylesheet xmlnssl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="/">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="segment">
<P>
Segment matched<xsl:value-of select="@Id"/>
<xsl:for-each select="type">
<xsl:if test=".='Green' and @Id='A01'"><br>
Value of A02 when A01 is Green:</br>
<xsl:for-each select="../type">
<xsl:choose>
<xsl:when test="@Id='A02'">
<xsl:value-of select="."/>
</xsl:when>
</xsl:choose>
</xsl:for-each>
</xsl:if>
</xsl:for-each>
</P>
</xsl:template></xsl:stylesheet>

Does this solve your problem?
Regards,
