that prints:number make color 2 Honda blue 4 Saab redbut I wantednumber make color 1 Honda blue 2 Saab redI'm checking to see if there's anyway to give arguments to position about depth, etc....

you could say, position()*0.5... but why is everything being multiplied by two?

Corey 2009-10-08 01:08:46

When you use `position()` in this context, XSLT is enumerating the child nodes of the `vehicle` element. The child nodes in the original example are: (1) a text node (a bunch of whitespace); (2) a `car` element; (3) a text node (more whitespace); (4) a `car` element; (5) a text node (more whitespace). So, when you match on `car` elements, you get element number 2 and number 4.

Answer 2

+1 A:

You can rearrange this a bit so that instead of using <xsl:apply-templates/>, do something like this:

<tr><td>number</td><td>make</td><td>color</td></tr>
<xsl:for-each select="/vehicle/car">
  <tr>
    <td><xsl:value-of select="position()" /></td><td>...</td>
  </tr>
</xsl:for-each>

In this case, the position() function will refer to the iteration number of the associated for-each loop. This may give you what you're looking for.

This would be my preferred method. I was just too lazy to type it out.

Answer 3

+1 A:

Minimal change:

<xsl:stylesheet 
  version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns="http://www.w3.org/1999/xhtml"
>
  <xsl:template match="/vehicle">
    <html>
      <body>
        <table cellpadding="5" border="1">
          <tr>
            <td>number</td>
            <td>make</td>
            <td>color</td>
          </tr>
          <xsl:apply-templates select="car" />
        </table>
      </body>
    </html>
  </xsl:template>

  <xsl:template match="car">
    <tr>
      <td><xsl:value-of select="position()" /></td>
      <td><xsl:value-of select="make" /></td>
      <td><xsl:value-of select="color" /></td>
    </tr>
  </xsl:template>

</xsl:stylesheet>

Note the select="car" attribute on the <xsl:apply-templates>. It makes sure that only <car> nodes are counted, so your position() is not off.

Also note that the main template now matches the document element, not the root node.
