RE: Changing Attribute Value in all the ChildNodes at any level down the

Hi Animesh,
  Please try the XSL -

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="xml" version="1.0"
encoding="UTF-8" indent="yes"/>

<xsl:template match="node()">
   <xsl:copy>            
     <xsl:if test="ancestor::csf">                   
       <xsl:apply-templates select="@*[not(name() =
'href')]"  mode="x"/>
       <xsl:apply-templates select="@*[name() =
'href']"  mode="y"/>
     </xsl:if>
     <xsl:if test="not(ancestor::csf)">
       <xsl:apply-templates select="@*"  mode="x"/>
     </xsl:if>
     <xsl:apply-templates />                   
   </xsl:copy>
</xsl:template>
        
<xsl:template match="@*" mode="x">
  <xsl:attribute name="{name()}">
     <xsl:value-of select="." />
  </xsl:attribute>
</xsl:template>
        
<xsl:template match="@*" mode="y">
   <!-- blank template -->
</xsl:template>
                
</xsl:stylesheet>

This removes the attribure "href" from the subtree of
node "csf".

For e.g., when the XSL is applied to XML -

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <body>
    <namespace>
      <form>
        <snip href="1" a="2" b="3">
          <csf href="4" c="5" d="6">
            <td href="7" e="8" f="9">                         <table
href="10" g="11" h="12">
                table1
              </table>
            </td>
          </csf>
        </snip>
      </form>
    </namespace>
  </body>
  <body>
    <namespace>
      <form>
        <snip href="1" a="2" b="3">
          <csf href="4" c="5" d="6">
            <td href="7" e="8" f="9">                         <table
href="10" g="11" h="12">
                table2
              </table>
            </td>
          </csf>
        </snip>
      </form>
    </namespace>
  </body>
</root>

it produces output ,

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <body>
    <namespace>
      <form>
        <snip href="1" a="2" b="3">
          <csf href="4" c="5" d="6">
            <td e="8" f="9">
              <table g="11" h="12">
                table1
              </table>
            </td>
          </csf>
        </snip>
      </form>
    </namespace>
  </body>
  <body>
    <namespace>
      <form>
        <snip href="1" a="2" b="3">
          <csf href="4" c="5" d="6">
            <td e="8" f="9">
              <table g="11" h="12">
                table2
              </table>
            </td>
          </csf>
        </snip>
      </form>
    </namespace>
  </body>
</root>

Thanks for the suggestion. 

But the problem is I wanted to retain the other part
of the original XML. It is something that I want to
modify the property (Attribute) of sub tree while
not touching the rest of Tree.

Something like:

<xsl:template

match="//body/namespace/form/snip/csf/td[position()=1]/table[position()=2]">

      <xsl:copy>
              <xsl:apply-templates
select="@*[not(name()='href')]"/>
              <xsl:apply-templates select="*|text()"/>
      </xsl:copy>
</xsl:template>

'Default Template
<xsl:template match="*|text()|@*">
      <xsl:copy>
              <xsl:apply-templates select="*|text()|@*"/>
      </xsl:copy>
</xsl:template>

And this thing doesn't works. Don't know why? 
May be Default template might reintroduce the
attribute removed by first template. 

Will changing priority of first template would be of
any help?

Thanks once again
Animesh

Hi,

I have to remove a particular attribute (in

following example it

is "href") from all the ChildNodes of the

particular node.


I tried to write template something as follows:

<xsl:template

match="//body/namespace/form/snip/csf/td[position()=1]/table[posit

ion()=2]">
    <xsl:apply-templates select="@*"/>
    <xsl:attribute name="href"/>


AFAIK, xsl:attribute is not a self-closing element,
so if you really want to
create an empty href attribute, at least there
should be
<xsl:attribute name="href"></xsl:attribute>

Although, I'm not sure whether this will work...
(haven't needed or tested
anything like it)

If you just want to omit the href attribute from
being output, you have two
options:

For both: remove the 'empty' xsl:attribute element
you specified above. It
serves no purpose.

1. replace <xsl:apply-templates select="@*" /> by
   <xsl:apply-templates
select="@*[not(name()='href')]" />

2. keep the current form of the apply-templates
instruction, and define a
null template matching @href, like <xsl:template
match="@href" />


Hope this helps!

Greetz,

Andreas
