xslt first letter
Jeffrey,

I should add -- the harder part is matching the correct text node.

In your case, assuming you want the character in bold to be the initial character inside the p, at any level,

<xsl:template match="text()[not(preceding::text()
  [count(.|current()/ancestor::p//text()) =
   count(current()/ancestor::p//text())])]">

would do it, but you can see how horrible that is!

Not foolproof, but

match="text()[starts-with(ancestor::p,.)]"

would usually work (and would most probably perform better).

So today's XSLT Challenge is to write a better match for this problem.

Cheers,
Wendell

XSLT 1.0 is not really a great string-processing language, which is what you need here, but its string handling is good enough to manage this ... you need the functions

substring($string, $start, $length)

and maybe substring-after($string, $substring)

So:

<xsl:template match="text()">
  <xsl:variable name="initial" select="substring(.,1,1)">
  <b><xsl:value-of select="$initial"/></b>
  <xsl:value-of select="substring-after(.,$initial)"/>
</xsl:template>

should do it. (The rest would be an identity transform.)

Wendell

I would like to be able to select the
first letter of the first text node
within a hierarchy, e.g., the "S" here:

  <content>
    <p><a href="...">Some</a> Text</p>
  </content>

and create a new element with that letter
while keeping the rest of the structure
as is, e.g:

  <content>
    <p><a href="..."><b>S</b>ome</a> Text</p>
  </content>
