 When this kind of thing appears, the simplest solution is to isolate just the bit that changes from the rest of the code: At 08:35 PM 5/13/2004, you wrote:
<xsl:element name="{$prefix}:rule" namespace="{$uri}"> <xsl:if test="string(@display)"> <xsl:attribute name="displayValue">{<xsl:value-of select="@display"/>}</xsl:attribute> </xsl:if> <xsl:attribute name="uid"> <res:choose>
<res:when test="*[name() = '{$prefix}:rule']">
<xsl:text>{*[name() = '</xsl:text>
<xsl:value-of select="$prefix"/>
<xsl:text>:rule']/@uid}</xsl:text>
</res:when>
<res:otherwise>
<xsl:text>{generate-id()}_</xsl:text>
<xsl:value-of select="$prefix"/>
</res:otherwise>
</res:choose> </xsl:attribute>
<xsl:attribute name="xpath">{$newXpath}</xsl:attribute>
<xsl:attribute name="type">{$type}</xsl:attribute>
<xsl:copy-of select="@*|node()"/>
</xsl:element>
</xsl:template>You can isolate this logic further: <xsl:template name="rule">
<xsl:param name="uri"/>
<xsl:variable name="prefix" select="../@prefix"/>
<xsl:variable name="uid-assign"> <res:choose>
<res:when test="*[name() = '{$prefix}:rule']">
<xsl:text>{*[name() = '</xsl:text>
<xsl:value-of select="$prefix"/>
<xsl:text>:rule']/@uid}</xsl:text>
</res:when>
<res:otherwise>
<xsl:text>{generate-id()}_</xsl:text>
<xsl:value-of select="$prefix"/>
</res:otherwise>
</res:choose></xsl:variable> <xsl:element name="{$prefix}:rule" namespace="{$uri}"> <xsl:if test="string(@display)"> <xsl:attribute name="displayValue">{<xsl:value-of select="@display"/>}</xsl:attribute> </xsl:if> <xsl:attribute name="uid"> <xsl:value-of select="$uid-assign"/> </xsl:attribute> <xsl:attribute name="xpath">{$newXpath}</xsl:attribute> <xsl:attribute name="type">{$type}</xsl:attribute> <xsl:copy-of select="@*|node()"/> </xsl:element> </xsl:template> which can be handy for parameterization, shortening the syntax, etc. (You will want to straighten up the indents in that code.) I hope that helps.
