Generating anchor tags

swwallace · March 8th, 2006, 10:49 AM

When I am building a table of summary values from my xml I'd like to generate an <a href='# + the xsl:value-of an element (an element such as <abc>100</abc> and then <abc>200</abc> for the next item, etc.) + '> so my result looks like <a href='#100'>100</a> and then further down in my result document where I use this value-of in a for-each detail section (to show the 100 details and then the 200 details, etc.) I would also need to generate the anchor, such as <a name='100'></a> at the beginning of the first loop, then <a name='200'></a> at the next loop, etc.

Maybe a better way to describe this is I am creating a kind of table of contents with my summary table at the start of my output doc. The user wants click on an underlined key to jump to the appropriate detail section below.

Do I put the xsl:value-of into a variable first and then somehow concatenate that into my anchor tags? Is there an example of this in Michael's XSLT Programmers Reference book?

Thanks.

I found info on page 492 of Michael's book for using generate-id() and can see the generated id when I hover over my hyperlink but it does not jump down the document to the anchor spot.

Here is a sample of the relevant XML:

<BillingProvider>
 <LX>
 <LX01>1</LX01>
 </LX>
 <TS3>
 <TS301>105590000</TS301>
 <TS302>11</TS302>
 <TS303>20041231</TS303>
 <TS304>10</TS304>
 <TS305>7395.6</TS305>
 <TS306>0</TS306>
 <TS307>0</TS307>
 <TS308>7395.6</TS308>
 <TS309>0</TS309>
 </TS3>
 <ClaimLineItem>

etc.... Further on down the <BillingProvider> section closes and a new one begins.

Here is my xslt that generates the summary table:

<xsl:for-each select="BillingProvider">
 <tr>
 <td><a href="#{generate-id(TS3/TS301)}">
 <xsl:value-of select="TS3/TS301"></xsl:value-of></a>
 </td>
 <td align="right">
 <xsl:value-of select="TS3/TS304"></xsl:value-of>
 </td>
 <td align="right">
 <xsl:text>$</xsl:text>
 <xsl:value-of select="format-number(TS3/TS305,'#,###.00')"></xsl:value-of>
 </td>
 <td align="right">
 <xsl:text>$</xsl:text>
 <xsl:value-of select="format-number(TS3/TS306,'#,###.00')"></xsl:value-of>
 </td>
 <td align="right">
 <xsl:text>$</xsl:text>
 <xsl:value-of select="format-number(TS3/TS308,'#,###.00')"></xsl:value-of>
 </td>
 <td align="right">
 <xsl:text>$</xsl:text>
 <xsl:value-of select="format-number(TS3/TS309,'#,###.00')"></xsl:value-of>
 </td>
 </tr>
 </xsl:for-each>

And here is the start of my detail section template:

 <xsl:template match="File/Detail/BillingProvider">

 <tr><a name="{generate-id()}"></a>
 <td colspan="17">[u]
 <xsl:value-of select="TS3/TS301"/>
 <xsl:variable name="billingproviderid" select="TS3/TS301"></xsl:variable>
 
 </td>
 </tr>

 <tr>
 <td class="Z">Client ID</td>
 <td class="Z">TCN</td>
 <td class="Z">Remit Line #</td>
 <td class="Z" valign="top">First</td>
 <td class="Z" valign="top">Middle</td>
 <td class="Z" valign="top">Last</td>
 <td class="Z">Mainecare ID</td>
 <td class="Z">Service From</td>
 <td class="Z">Service To</td>
 <td class="Z">Procedure Code</td>
 <td class="Z">Srvc Prov ID</td>
 <td class="Z">Units</td>
 <td class="Z">Billed</td>
 <td class="Z">Paid</td>
 <td class="Z">Adj.</td>
 <td class="Z">Code</td>
 <td class="Z">Remark</td>
 </tr>

 <xsl:for-each select="ClaimLineItem">
 <xsl:sort select="NM1/NM103"/>
 <tr>
 <td>

 <xsl:choose>
 <xsl:when test="$billingproviderid = '105590000'">
 <xsl:value-of select="translate(substring(CLP/CLP01,1,5),'XXX',' ')"/>
 </xsl:when>
 <xsl:otherwise>
 <xsl:text>NA</xsl:text>
 </xsl:otherwise>
 </xsl:choose>
 </td>
etc....

So, I'm maybe halfway there but, again, the name anchor tags (<a name=xxxx></a> do not appear to be working.

The anchor <a name=""> contains the generate-id() of a BillingProvider element. The link <a href=""> contains the generate-id() of a TS301 element. These aren't going to match.

Ah, so you made me look closer at what I was doing. So...

I changed this:
<a href="#{generate-id(TS3/TS301)}">

To this:
<a href="#{generate-id(.)}">

And, success!
