How to choose different nodes in the same name with different attributes

JohnKiller · August 3rd, 2011, 03:21 PM

input xml:
<response>
--<para pos="0">
----<aaa>Hi, there.</aaa>
------<aaaA>Nested,lol</aaaA>
--<para pos="1"/>
--<para pos="2">646464</para>
--<para>123456</para>
--<para pos="3"/>
--<para pos="4"/>
--<para pos="5">0</para>
--<para>WHAT IS THIS?</para>
--<para pos="6"/>
--<para pos="7">N</para>
--<para>
----<presc>45864</presc>
----<pred>Help!</pred>
--</para>
--<para pos="8"/>
--<para pos="9"/>
--<para pos="10"/>
--<para pos="11"/>

the output xml：
<AV>
--<Address attr1="Hi, there." pa="Nested,lol" fc="123456" nf="WHAT IS THIS?"/>

I need the xsl to:
1. How to choose different node with the same name, but different attribute?

2. How to deal with the node in the red color? These are following the previous line, just with the same node name. Like the father and child have the same name.

I do not know whether I explain the question clear.

Thank you in advance for help.

If you want to select a specific node then use something like this:

Code:

para[@pos='2']

If you want the next para element after this one then use something like this:

Code:

para[@pos='2']/following-sibling::para[1]

So the complete template might look like this:

Code:

<xsl:template match="response">
<AV>
  <Address attr1="{para[@pos='0']/aaa}" pa="{para[@pos='0']/aaaA}" fc="{para[@pos='2']/following-sibling::para[1]}" nf={para[@pos='5']/following-sibling::para[1]}"/>
</AV>
</xsl:template>

I changed the output a little bit,

<AV>
--<Address attr1="Hi, there." pa="Nested,lol" fc="123456" nf="WHAT IS THIS?" ab="45864" bc="Help!"/>

And I do not know how to output the "Help!"

Thank you, Sam!

By the way, what kind of tools or program you used to test these xsl?

Thank you, Sam!

well if there is only one <para> that has a <pred> element then bc="{para/pred}" would work. Otherwise just add "/pred" onto the end of an xpath similar to one you already have to select the child <pref> element.

Oh, and I use Kernow for Saxon to test my XSLT.

Thank you so much, Sam. I am confusing about parameter[1] in the
/following-sibling::parameter[1]
What does the [1] mean? Can it be changed to [2] or [0] in some situations?

samjudson · August 4th, 2011, 02:09 PM

The 1 means the first one (i.e. the first sibling that is a 'parameter' element).

Thank you, Sam.

And the tool is really really great!
