Re: How to trim leading and trailing spaces in xsl:at

Hi, David,

Take a peek at the normalize-space function. You can use it like this:

<xsl:attribute name="myAttribute"><xsl:value-of 
select="normalize-space(widget)"/></xsl:attribute>

A useful shortcut, by the way:

<xsl:attribute name="myAttribute" select="normalize-space(widget)"/>

Speaking of shortcuts, you can use an Attribute Value Template (AVT) for a 
lot of these kinds of issues. For example:

<xsl:element name="something">
  <xsl:attribute name="myAttribute"><xsl:value-of 
select="normalize-space(widget)"/></xsl:attribute>
</xsl:element>

can often be replaced by:

<something myAttribute="{normalize-space(widget)}"/>

Of course, you occasionally must use the more verbose way, such as for 
attributes that are present sometimes and absent other times.

 How to trim leading and trailing spaces in xsl:attribute?






I have an "<xsl:attribute>" element in my stylesheet, and its value is
an "<xsl:value-of>" reference which then calls an XPATH function.  The
resulting single line is a little ugly.  I'd like to format the line so
it's a little more readable.  Unfortunately, I appear to be limited by
the semantics of the "<xsl:attribute>" element.  It does not trim
leading and trailing spaces, and it encodes any newlines found in the
resulting value.

I'm using JDK 1.4.2, in case there are constraints in the native TRAX
implementation inherent in that.
