To restrict the p tags and br tags in Tridion RTF fields I am writing XSLT code. But at any time only one tag I can able to remove with the following code. Please correct me where I am doing wrong. Input XML:

    <html>
     <body>
      <p>This is the content in p tag.</p>
       <br/><br/>
       Content after br tag.
     </body>
    </html>

Expected output:

<html>
   <body>
      This is the content in p tag.Content after br tag.      
   </body>
</html>

XSLT written in Schema source:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"  xmlns:xh="http://www.w3.org/1999/xhtml">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>
 <xsl:template match="node()|@*">
     <xsl:copy>
       <xsl:apply-templates select="node()|@*"/>
     </xsl:copy>
 </xsl:template>
 <xsl:template match="p|br">
    <xsl:apply-templates/>
  </xsl:template>
</xsl:stylesheet>

When I am trying the same code in online XSLT editors it is working fine. But when I test in Tridion it is not working. I also referred Bart Koopman post for this question. Thanks in Advance.

As for the XSLT required, try using the following Filtering XSLT

<stylesheet xmlns="http://www.w3.org/1999/XSL/Transform" version="1.0">
  <output omit-xml-declaration="yes" method="xml" cdata-section-elements="script"></output>
  <template match="/ | node() | @*">
    <copy>
      <apply-templates select="node() | @*"></apply-templates>
    </copy>
  </template>
  <template match="p|br">
    <apply-templates></apply-templates>
  </template>
  <template match="*[      (self::br or self::p or self::div)     and      normalize-space(translate(., &apos; &apos;, &apos;&apos;)) = &apos;&apos;     and      not(@*)     and      not(processing-instruction())     and      not(comment())     and      not(*[not(self::br) or @* or * or node()])     and      not(following::node()[not(         (self::text() or self::br or self::p or self::div)        and         normalize-space(translate(., &apos; &apos;, &apos;&apos;)) = &apos;&apos;        and         not(@*)        and         not(processing-instruction())        and         not(comment())        and         not(*[not(self::br) or @* or * or node()])       )])     ]">
    <!-- ignore all paragraphs and line-breaks at the end that have nothing but (non-breaking) spaces and line breaks -->
  </template>
  <template match="br[parent::div and not(preceding-sibling::node()) and not(following-sibling::node())]">
    <!-- Chrome generates <div><br/></div>. Renders differently in different browsers. Replace it with a non-breaking space -->
    <text> </text>
  </template>
</stylesheet>

This removes the <p> and <br/> on Save or when you switch between the Design and Source tab of your Format Area. The trick is to place the removal of these element above the default handing of p and br (although you can probably experiment with removing those, or adjusting them a bit).

  • What will happen if in source document XHTML tags will have NS attached, e.g.: <p xmlns="w3.org/1999/xhtml">? My experiments (using XslCompiledTransform class) show that such <p/> will be stripped off. Is there any cure for this? – esteewhy Aug 21 '13 at 7:47
  • I think the content of an RTF field is considered XHTML, so that should just work. But I'm not sure how the exact inner details of it all work though. – Bart Koopman Aug 21 '13 at 14:02

Bart answer was the one you need to use.

You need to include the default tridion template part (that is first 3 templates) and then you need to add your required template match.

<stylesheet xmlns="http://www.w3.org/1999/XSL/Transform" version="1.0">
    <output omit-xml-declaration="yes" method="xml" cdata-section-elements="script"/>
    <template match="/|node()|@*">
        <copy>
            <apply-templates select="node() | @*"/>
        </copy>
    </template>
    <template match="*[      (self::br or self::p or self::div)     and      normalize-space(translate(., &apos; &apos;, &apos;&apos;)) = &apos;&apos;     and      not(@*)     and      not(processing-instruction())     and      not(comment())     and      not(*[not(self::br) or @* or * or node()])     and      not(following::node()[not(         (self::text() or self::br or self::p or self::div)        and         normalize-space(translate(., &apos; &apos;, &apos;&apos;)) = &apos;&apos;        and         not(@*)        and         not(processing-instruction())        and         not(comment())        and         not(*[not(self::br) or @* or * or node()])       )])     ]">
        <!-- ignore all paragraphs and line-breaks at the end that have nothing but (non-breaking) spaces and line breaks -->
    </template>
    <template match="br[parent::div and not(preceding-sibling::node()) and not(following-sibling::node())]">
        <!-- Chrome generates <div><br/></div>. Renders differently in different browsers. Replace it with a non-breaking space -->
        <text> </text>
    </template>
    <!-- remove disallowed elements but keep its children -->
    <template match="p|br">
        <apply-templates/>
    </template>
</stylesheet>
  • Those two other templates already exist in the schema source. Still I am unable to achieve it. Are you able to remove two tags? Please help me out. – P.Muralikrishna Apr 8 '13 at 6:54
  • @P.Muralikrishna: Have you tried copy and pasting the template on the Filtered XSLT tab, with the one I gave? – Siva Charan Apr 8 '13 at 7:13

    @P.Muralikrishna: After adding the XSLT, please close the browser, clear browser cache and then open it again. – Siva Charan Apr 8 '13 at 7:15
  • Just clearing the cache and re arranging the templates as Bart said solved my issue. – P.Muralikrishna Apr 8 '13 at 10:43
