Re: [xsl] xml as parameter from servlet

[Robert Koberg <rob at koberg dot com>]

Hi again,

Maybe I am going about this the wrong way. Perhaps there is a simpler 
XSLT/java way?

I have a multi select list box that lists the contents of a folder on a 
web site. This list is the labels (with the value being the 
corresponding ID) that would appear in a nav.

The  user moves folder items up and down to change the order in which 
they are displayed in the nav.

On submit i get a comma delimted String of IDs that I split on the 
server to make the nodeset I am passing to the transformation.

The transformation loops on the nodeset passed in and reorders the 
folder, like so:

<xsl:param name="nav_order"/>

<xsl:template match="folder">

    <xsl:copy>
        <xsl:copy-of select="@*"/>
       
        <xsl:choose>
            <xsl:when test="@id=$nav_order/order/@id">
   
                <xsl:variable name="current_nodeset" select="."/>
               
                <xsl:for-each select="$nav_order/order/item">
                        <xsl:variable name="id" select="@id"/>
                        <xsl:apply-templates 
select="$current_nodeset/*[@id=$id]" mode="sorted"/>
                </xsl:for-each>
   
                </xsl:when>
            <xsl:otherwise>
               
                    <xsl:apply-templates/>
               
           </xsl:otherwise>
        </xsl:choose>
   
    </xsl:copy>
      
</xsl:template>

<xsl:template match="folder | page | col" mode="sorted">

    <xsl:copy>
        <xsl:copy-of select="@*"/>
        <xsl:apply-templates/>
    </xsl:copy>
           
</xsl:template>

<xsl:template match="node()|@*">

    <xsl:copy>
        <xsl:copy-of select="@*"/>
        <xsl:apply-templates/>
    </xsl:copy>
       
</xsl:template>

Is there a better way to do this?

best,
-Rob
