Re: [xsl] Seek an elegant way to remove a sub-tree from an element

Use the modified-identity-transformation pattern:

<xsl:template match="*|node()">
<xsl:copy><xsl:apply-templates select="@*|node()"/></xsl:copy>
</xsl:template>

<xsl:template match="xs:simpleType//xs:simpleType"/>

However, note that your desired output is not a valid XSD document fragment.

Hi Folks,

This simpleType element contains within it another simpleType element:

<xs:simpleType name="BostonAreaElevation">
         <xs:restriction>
                 <xs:simpleType>
                         <xs:restriction base="xs:int">
                                 <xs:minInclusive value="-1290" />
                                 <xs:maxInclusive value="29035" />
                         </xs:restriction>
                 </xs:simpleType>
                 <xs:minInclusive value="0" />
                 <xs:maxInclusive value="120" />
         </xs:restriction>
</xs:simpleType>

I want to remove the inner simpleType, thus producing:

<xs:simpleType name="BostonAreaElevation">
         <xs:restriction>
                 <xs:minInclusive value="0" />
                 <xs:maxInclusive value="120" />
         </xs:restriction>
</xs:simpleType>

I seek an elegant way to accomplish this.

The following is one way to accomplish it. Is there a more elegant way to 
accomplish it?

<xsl:variable name="outer-simpleType">
         <xsl:element name="simpleType" 
namespace="{namespace-uri($simpleType)}">
                 <xsl:copy-of select="$simpleType/namespace::*" />
                 <xsl:for-each select="$simpleType/@*">
                         <xsl:attribute name="{name(.)}"><xsl:value-of select="." 
/></xsl:attribute>
                 </xsl:for-each>
                 <xsl:element name="restriction" 
namespace="{namespace-uri(simpleType/xs:restriction)}">
                         <xsl:copy-of 
select="$simpleType/xs:restriction/namespace::*" />
                         <xsl:for-each select="$simpleType/xs:restriction/@*">
                                 <xsl:attribute name="{name(.)}"><xsl:value-of 
select="." /></xsl:attribute>
                         </xsl:for-each>
                         <xsl:sequence 
select="$simpleType/xs:restriction/xs:*[not(self::xs:simpleType)]" />
                 </xsl:element>
         </xsl:element>
</xsl:variable>
