Re: Re: Re: Sibling in the Pattern(match)

The following template can act like a filter since it
does nothing. The attribute "match" here indicate what
needs to be filtered out from the output.

<xsl:template match="*[preceding-sibling::Member[(_at_)name
='acc1']/Member[(_at_)name='acc11']]"/>


Here I wanted to remove(filter out) the element
Member(name attribute is "acc12") and its children
from the output. It is the sibling of the element
Member(name attribute is "acc11").


Use:

  <xsl:template
   match="*[preceding-sibling::Member
                          [(_at_)name='acc11']
            ]"/>

This removes any element that is a following-sibling of a "Member" element
whose "name" attribute's value is "acc11".

In the case of the source xml provided by you, the element removed will be a
"Member" element with "acc12" as the value of its "name" attribute.

All the children of this removed element will also be removed, because they
are not processed at all.

So, given this source.xml:

<D>
  <Member comment="" name="acc1">
    <Calc>+</Calc>
    <Member comment="" name="acc11">
      <Calc>+</Calc>
      <Member name="account3_1"/>
    </Member>
    <Member comment="" name="acc12">
      <Calc>+</Calc>
      <Member name="acc121"/>
    </Member>
  </Member>
  <Member comment="" name="acc2">
    <Calc>+</Calc>
  </Member>
  <Member comment="" name="acc3">
    <Calc>+</Calc>
    <Member comment="" name="acc31">
      <Calc>+</Calc>
    </Member>
    <Member comment="" name="acc32">
      <Calc>+</Calc>
    </Member>
  </Member>
</D>

When we apply this transformation on it:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

 <xsl:output omit-xml-declaration="yes"/>

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

  <xsl:template
   match="*[preceding-sibling::Member
                          [(_at_)name='acc11']
            ]"/>

</xsl:stylesheet>

the wanted result is produced:

<D>
  <Member comment="" name="acc1">
    <Calc>+</Calc>
    <Member comment="" name="acc11">
      <Calc>+</Calc>
      <Member name="account3_1"></Member>
    </Member>

  </Member>
  <Member comment="" name="acc2">
    <Calc>+</Calc>
  </Member>
  <Member comment="" name="acc3">
    <Calc>+</Calc>
    <Member comment="" name="acc31">
      <Calc>+</Calc>
    </Member>
    <Member comment="" name="acc32">
      <Calc>+</Calc>
    </Member>
  </Member>
</D>
