Subject: position()=last()

I do not understand why the line of the code is NOT being tested
as TRUE.

Refer lines 153: in the XSLT

<xsl:when test="position()=last()">
<u>
<xsl:value-of select="n:Total"/>
</u>
</xsl:when>

I want the "underline" to appear in my HTML output.

Files attached.

Thanks

Peter

Because the xsl:choose instruction is embedded inside an outer xsl:when (xsl:when test="n:Type='D' and n:Text != 'Total' ")
In other words, in the last loop interaction (position()=last()) the last element <n:FeeLine> has n:Type = GT so it gets never evaluated.

Hope this helps
Ivan

Thanks for the Help Ivan.

The XML value that I want underlined, and which gets evaluated is:

<n:Text>Filing Fee:</n:Text>
<n:Total>320.00</n:Total>
<n:Type>D</n:Type>

This element is part of the inner test.

So I must be misunderstanding the function "position()=last()"

meaning, becuase I test="where n:Type='D' and n:Text !='Total'

with this test I should only return 2 elements.

Thereby last() should return me

<n:Text>Filing Fee:</n:Text>
<n:Total>320.00</n:Total>
<n:Type>D</n:Type>

Am I missing something here with those functions?

test="where n:Type='D' and n:Text !='Total'

Anoth example if I did count(.), I would guess that this should return
2 ?

Thanks

Pete

The xsl:choose doesn't restrict the number of time you execute the loop.

You need you apply a predicate to do so

<xsl:for-each select="n:TaxInvoices/n:Invoice/n:Fees/n:FeeLine[n:Type='D' and n:Text != 'Total']" xml:space="">
<tr>
<td colSpan="96"><xsl:value-of select="n:Text"/></td>
<td align="right" colSpan="4">
<xsl:choose>
<xsl:when test="position()=last()">
<u><xsl:value-of select="n:Total"/></u>
</xsl:when>
<xsl:otherwise><xsl:value-of select="n:Total"/></xsl:otherwise>
</xsl:choose>
</td>
</tr>
</xsl:for-each>

Most of your loops that extract totals can be re-written as single instruction like that:

<tr>
<td colSpan="96"/>
<td align="right" colSpan="4">
<xsl:value-of select="n:TaxInvoices/n:Invoice/n:Fees/n:FeeLine[n:Type='P' and n:Text = 'Total']/n:Total"/>
</td>
</tr>

brilliant, I will test your answer

Yes, I thought that my loops were not good but I did not have the
answer.
