Question

xslt to operate on element value before displaying?

Answer 1

+2 A:

Update: Only works in XPath 2.0-supporting processor.

I think the following should do what you want... don't forget to declare the fn namespace (xmlns:fn=...) or declare no namespace at all.

<?xml version="1.0" encoding="ISO-8859-1"?>
<!-- Edited by XMLSpy® -->
<xsl:stylesheet version="1.0"
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   xmlns:fn="http://www.w3.org/2005/xpath-functions"&gt;

<xsl:template match="/">
  <html>
  <body>
  <h2>My CD Collection</h2>
    <table border="1">
      <tr bgcolor="#9acd32">
        <th>Title</th>
        <th>Artist</th>
      </tr>
      <xsl:for-each select="catalog/cd">
      <tr>
        <td><xsl:value-of select="fn:upper-case(title)"/></td>
        <td><xsl:value-of select="artist"/></td>
      </tr>
      </xsl:for-each>
    </table>
  </body>
  </html>
</xsl:template>
</xsl:stylesheet>

There's no `upper-case` in XPath 1.0 (and consequently in XSLT 1.0).

Pavel Minaev 2009-09-23 21:17:46

Let me just check that, this stylesheet works fine under Saxon-B 9.1.0.6

Brabster 2009-09-23 21:20:06

Yep, Pavel is of course correct. These functions are available in XPath 2.0, so I suspect not on the w3schools site. If you use an XPath 2.0-compliant processor you can use them as above. Otherwise, you'll need to build a function to do it yourself.

Brabster 2009-09-23 21:23:28

well traditionally translate has been leaned on for this, as I mentioned, but it's kind of ghetto

didn't know that @annakata. Think the info warrants an up-vote form me :)

Answer 2

A:

The link to the list of functions that you give is for XPath 2.0, XSLT 2.0 and XQuery 1.0. The stylesheet that you link to is XSLT 1.0, which does not support most of those functions. In particular, it does not support upper-case().

Answer 3

+4 A:

upper-case is an XSLT 2.0 function. If you happen to have a 2.0 stylesheet (which the example is not) and engine to transform it then using it is as simple as:

<xsl:value-of select="upper-case(title)"/>

However, in the sadly still more common 1.0 your best plan is to use one of:

a custom extension (platform varying)
the tedious xslt translate function as translate(title,'abcdefghijklmnopqrstuvwxyz','ABCDEFGHIJKLMNOPQRSTUVWXYZ') which is crude and problematic with I18N
CSS's simple text-transform:uppercase; (generally the best solution because this is usually a style issue not a data issue)

annakata 2009-09-23 21:21:42

What is the minimal change to the original page XSL code to apply this "CSS's simple text-transform:uppercase;" solution?

@downvoter - wth?

annakata 2009-09-30 21:40:35

Answer 4

+2 A:

Since the XSL on that page is version="1.0", you can change this line

<td><xsl:value-of select="title"/></td>
                          ^^^^^

to this:

<td><xsl:value-of select="translate(title, 'abcdefghijklnmopqrstuvwxyz', 'ABCDEFGHIJKLNMOPQRSTUVWXYZ')"/></td>
                          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Although with a processor that supports XPath 2.0 you should be able to use this instead:

<td><xsl:value-of select="upper-case(title)"/></td>
                          ^^^^^^^^^^^^^^^^^

Much appreciate the discussion of versions 1.0 and 2.0 of XPath and XSLT (so that I learn that these versions exist). But I've accepted this simplest answer because (a) it appears to be the correct answer to exactly the question I asked and (b) it works on the page that I gave. But thanks to all responders!

talkaboutquality 2009-09-25 09:22:30

Further, this answer makes it very clear to me how I insert a function call into a select statement on an element name. That is, starting with the fragment select="title"it had not been clear to me where I would put the function name and its parentheses. Now it is clear.

talkaboutquality 2009-09-25 09:24:37

I guess I can't edit earlier comments? So updating my first comment, I see that this answer also addressed version 2.0 briefly. This answer was short, concise, and correct. That's why I have accepted it.
