Re: [xsl] Including markup in a replace string

Using disable-output-escaping is always a bad idea unless there are very good 
reasons indeed, which isn't the case here.

The reason is that it only works if your transformation is immediately followed 
by serialization, and that immediately reduces the flexibility and reusability 
of your XSLT code. Transformations rarely happen in isolation, they are usually 
executed as part of a pipeline, and constructing a pipeline immediately becomes 
more difficult if you have to serialize the output of one step and the re-parse 
it as input to the next.

It can look like a tempting short-cut, but you (or your successors) will regret 
it.

Hi Craig,

I think we should use "disable-output-escaping="yes"" here.

Below is the code for expected output.

<xsl:value-of select="replace($pattern,'(\{\{|\}\})','&lt;span 
class=&quot;noProcess&quot;&gt;$1&lt;/span&gt;')" 
disable-output-escaping="yes"/>

Subject: [xsl] Including markup in a replace string
 
Hi All,
  I have code examples in some doc that are post processed in AngularJS. In 
some cases the code examples include “{{“ or “}}” which is significant to 
Angular. I have a simple replace that I am using to wrap a no-process span 
around the curly braces so the Angular process will ignore them.
 
  <xsl:value-of select="replace(.,'(\{\{|\}\})','&lt;span 
class=&quot;noProcess&quot;&gt;$1&lt;/span&gt;')"/>
 
  The only problem is that the character entity is being output as a 
character entity instead of less-than and greater-than characters.
 
  Is there a way to trick replace into outputting the less-than and 
greater-than characters?
 
  I’ve tried entering the actual characters – doesn’t work. I’ve tried 
escaping the characters with backslashes – doesn’t work either.
 
  So unless there’s a way to trick replace I’ll have to try analyze-string 
and see if I can get what I need there.
 
Thanks,
  Craig
 
Here’s an example of what I need:
 
<span class="noProcess">{{</span>This variable<span 
class="noProcess">}}</span>
