What diferense between xsl:variable with select and without select?

Why the code

  <xsl:variable name="title" select="$node/data[@alias='nodeTitle']">
  </xsl:variable>

returnt title

but the code

  <xsl:variable name="title">
        <value-of select="$node/data[@alias='nodeTitle']" />
  </xsl:variable>

return empty ?

I need get $node/data[@alias='nodeTitle'] or $node/@nodeName and the code

  <xsl:variable name="title">
    <xsl:choose>
      <xsl:when test="$node/data[@alias='nodeTitle']">
        <value-of select="$node/data[@alias='nodeTitle']" />
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="$node/@nodeName" />
      </xsl:otherwise>
    </xsl:choose>
  </xsl:variable>

return empty.

Hi Alex,

With your second code snippet, you are missing the "xsl:" namespace prefix, so it doesn't work:
```
 <xsl:value-of select="$node/data[@alias='nodeTitle']" />
```
Cheers, Lee.

The reason there is no error... is because, there is no error. The syntax is correct. As far as the XSLT is concerned the tag you used <value-of ... /> is just arbitrary XML. Errors will occur if you tried to use an incorrect XSLT tag, i.e. <xsl:whatever> because that isn't defined in the XSLT namespace.

Hi

I'm guessing that you don't get any error since the element is actually being wellformed so the parser does not notice that it should in fact have been prefixed with a namespace.

Hi,

because this is totally valid xml (xslt) you need to prefix with xsl: that the xslt-processor knows what to do with it.
