Re: XSL Sort and Xalan

["Bryce Wells" <bryce at impulseradio dot com>]

Jeni,

The problem, perhaps, is that I'm not storing the data that way? - let me
elaborate.

Here's my XML file:

<OBJECT_TABLE>
        <RECORD>
               <ID>001</ID>
               <TIME>06:00:00</TIME>
               <LENGTH>1:35</LENGTH>
               <DESCRIPTION>CCC Record</DESCRIPTION>
        </RECORD>
</OBJECT_TABLE>

Using the following XSL, I am rendering this data into an HTML table:

<table>
<xsl:for-each select="OBJECT_TABLE">
    <xsl:sort select="RECORD/TIME" order="ascending"/>
        <tr>
        <xsl:for-each select="RECORD">
           <xsl:for-each select="ID">
               <td><input type="checkbox" name="arrSelect"
value="{.}"/></td>
           </xsl:for-each>
           <xsl:for-each select="TIME">
               <td><xsl:value-of select="."/></td>
           </xsl:for-each>
           <xsl:for-each select="LENGTH">
               <td><xsl:value-of select="."/></td>
           </xsl:for-each>
           <xsl:for-each select="DESCRIPTION">
               <td><xsl:value-of select="."/></td>
           </xsl:for-each>
        </xsl:for-each>
        </tr>
</xsl:for-each>
</table>

Which looks roughly like this and is sorted, correctly, by TIME

[]       06:00:00       1:35            CCC Record
[]       06:01:35       2:00            AAA Record
[]       06:03:35       3:33            BBB Record

and so forth . .

But, I would like the end-user to be able to sort this data in the HTML
page, without making another call to the database (which is generating the
XML)  - and was hoping to accomplish this by creating a parameter that would
trigger the proper column to sort.

So, I created the parameter and gave it a static value (I'll pass them
dynamically later)
<xsl:param name="item" select="'RECORD/LENGTH'"/>

and I can get that value to show on my HTML page using:
<xsl:value-of select="$item"/>

but what I cannot do is:

<table>
<xsl:for-each select="OBJECT_TABLE">
    <xsl:sort select="$item" order="ascending"/>
        <tr> . . .

Any additional insights would be greatly appreciated.

Thanks,
Bryce
