XSL Strip Padding

Question

Is there a simple way to strip padding, IE leading and/or trailing white space. EXSLT padding function seems to only create padding or trim strings to a certain length.

Answer 1

Would normalize-space() do the job for you? This will also reduce spaces inside the string, e.g.

"  this         string    " 

would become:

"this string"

If you really need a "trim" function, you can probably steal one from someone else who's already implemented it with normalizse-space()...

Answer 2

Try normalize-space

<xsl:value-of select='normalize-space(string)'/>

Answer 3

It isn't clear what is wanted -- what is "strip padding"?

If you meant the trim() function, then

The FXSL library provides a convenient trim template function.

This transformation:

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

  <xsl:import href="trim.xsl"/>

  <xsl:output method="text"/>
  <xsl:template match="/">
    '<xsl:call-template name="trim">
        <xsl:with-param name="pStr" select="string(/*)"/>
    </xsl:call-template>'
  </xsl:template>
</xsl:stylesheet>

when applied on this XML document:

<someText>

   This is    some text   

</someText>

produces the wanted, correct result:

'This is    some text'
