Re: position() always 1 in for-each

From: "Joe Fawcett" <joefawcett@---------.------>

You say you've solved it but here are a few points:
* Your XML was not well-formed. If you remove the extra root tag then your 
original code will work, not sure if that's what you meant
* You are better off getting into the habit of using templates rather than 
for-each, they are more maintainable and get you out of the procedural mind 
set
* You can simplify the code in general by using Attribute Value Templates, 
take a look online
* Your xsl:choose means a lot of duplicated code, always a bad thing

I have rewritten the stylesheet to show these points based on the following 
XML:

<root>
<user>
<account>1234</account>
<name>Joe Smith</name>
<neverexp>True</neverexp>
</user>
<user>
<account>5678</account>
<name>Jane Brown</name>
<neverexp>False</neverexp>
</user>
</root>

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:template match="/">
    <xsl:apply-templates select="root/user" />
  </xsl:template>

  <xsl:template match="user">
    <tr>
    <td><xsl:value-of select="account" /></td>
    <td><xsl:value-of select="name"/></td>
    <td align="center">
      <input type="radio" name="{position()}"><!-- attribute value template 
used for 'name attribute' -->
        <xsl:if test="neverexp='True'">
          <xsl:attribute name="checked">checked</xsl:attribute>
        </xsl:if>
      </input>
    </td>
    <td align="center">
      <input type="radio" name="{position()}"></input>
    </td>
  </tr>
  </xsl:template>
</xsl:stylesheet>
