Using XSLT to transform XML

Question

I have the following set XML content (basically, multiple lines with three items

in it) which I want to transform as follows: Instead of having:

 <line><li>1</li><li>2</li><li>3</li></line> <line><li>a</li><li>b</li><li>c</li></line> <line><li>x</li><li>y</li><li>z</li></line> 

I would like to have:

 <line> <item1>col1<item1><li>1</li> <item2>col2<item1><li>2</li> <item3>col3<item1><li>3</li> </line> <line> <item1>col1<item1><li>a</li> <item2>col2<item1><li>b</li> <item3>col3<item1><li>c</li> </line> <line> <item1>col1<item1><li>x</li> <item2>col2<item1><li>y</li> <item3>col3<item1><li>z</li> </line> 

Basically adding a column for ech line. Does XSLT help achieving that result? Many thanks.

Answer 1

I tried a slightly modified verion. My input XML is:

<message>
<line number="1"><li>1</li><li>2</li><li>3</li></line>
<line number="2"><li>x</li><li>y</li><li>z</li>
</line>
<line number="3"><li>a</li><li>b</li><li>c</li>
</line>
</message>

And my XSLT is:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" encoding="utf-8" indent="no"/>
<xsl:template match="/">
  <xsl:for-each select="/message/line">

number: <xsl:value-of select="@number"/>
position: <xsl:value-of select="position()"/>
all items: <xsl:value-of select="."/>
item[3]: <xsl:value-of select="li[3]"/>

  </xsl:for-each>
</xsl:template>

This yields:

number: 1
position: 1
all items: 123
item[3]: 3

number: 2
position: 2
all items: xyz
item[3]: z

number: 3
position: 3
all items: abc
item[3]: c

My initial thoughts were to put the all items in a variable and then do the second nested for-each on that variable. But what it yields is 123 (for the first line), ommitting the

tags. Interestingly, when I try with the following XPath on the message:

 /message/line[1]/li 

I obtain:

 <li>1</li> <li>2</li> <li>3</li> 

which is the desired outcome. In my XSLT, I tried to replace "select="."" with "select="li[position()]"" but it would only return the 1st item of each line.

Is there any explanation and what should I change to get the same outcome as my xPath?
