XSL question

In the following XML, there is a ID_LIST and a USER_LIST.
The XSL below loop through the ID_LIST and try to find out whether the ID contains in the ID_LIST exist in USER_LIST or not.

In my XSL, it can show the ID if it is exist, but it cannot show the ID if it is not exist in the USER_LIST.

Anyone got a solution? Thanks.


XML:

<MyXML>
<ID_LIST>
<ID>1</ID>
<ID>22</ID>
<ID>5</ID>
</ID_LIST>
<USER_LIST>
<UID>5</UID>
<UID>17</UID>
</USER_LIST>
</MyXML>

XSL:
<xsl:for-each select="/MyXML/ID_LIST/ID">
<xsl:variable name="MYID">
<xsl:value-of select="./ID"/>
</xsl:variable>
<xsl:for-each select="/MyXML/USER_LIST/UID">
<xsl:if test="$MYID = .">
ID: <xsl:value-of select="$MYID"/> EXIST!
</xsl:if>
</xsl:for-each>
</xsl:for-each>

Try This:

<?xml version='1.0'?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:template match="/">
<xsl:for-each select="/MyXML/ID_LIST/ID">
<xsl:variable name="MYID">
<xsl:value-of select="."/>
</xsl:variable>
<!--<xsl:for-each select="/MyXML/USER_LIST/UID">-->
<xsl:choose>
<xsl:when test="//USER_LIST/UID = $MYID">
<!-- EXIST! -->
<xsl:text>User ID exists: </xsl:text>
<xsl:value-of select="$MYID"/>
<xsl:text>
</xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:text>User ID DOES NOT exist: </xsl:text>
<xsl:value-of select="$MYID"/>
<xsl:text>
</xsl:text>
</xsl:otherwise>
</xsl:choose>
<!--</xsl:for-each>-->
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

I commented out your nested loop and changed your <if> to a <choose> that just checks for existence of any UID with the current value. Attached is the xsl and text xml.

Hope this helps.
