[xsl] Re: Add element at the end of a variable group of elements

["Charles O'Connor coconnor@xxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

It should be added no matter what, so I believe the solutions presented here
will work for my use case. The one wrinkle is that a <moon> element may
already exist and should be replaced, but I believe I can handle that with my
current (such as they are) skills.

Thank you everyone for your answers. I really love this board and have gotten
several solutions here, each of which has expanded my idea of what can be done
with XSLT. I do hope to get good enough eventually to be able to contribute
solutions as well. I just looked, and I'm on Step 10 (of ~70) of Ken's
"Practical Transformation . . . " class on Udemy. Eventually . . .

Liam, I will continue to annoy my IT/Engineering group to upgrade to a 3.0
processor. I suspect I'll get the same response.

Are there any conditions for adding <moon> -- like, add <moon> only if
<earth>?  Or do you want to add it 100% of the time, no matter what?

Subject: [xsl] Add element at the end of a variable group of elements

Hi all,

Using XSLT 2.0, I'd like to add an element at the end of a group of elements
that may vary whether they exist.

This seems like a classic case that people have to deal with all the time, but
I've searched without luck, and I'm on maybe lesson 4 of ??? of the online
XSLT course I've been taking for the past decade.

So, given the XML

<root>
   <foo/>
   <bar/>
   <mercury/>
   <venus/>
   <earth earth-type="round"/>
   <earth earth-type="flat"/>
   <mars/>
</root>

I want to add <moon>Now with more craters!</moon> after the <foo>, <bar>,
<mercury>, <venus> group of elements and before the <earth>, <mars> group of
elements, BUT I only know for sure that <foo> and <mars> will exist in the
input XML. All the others are optional.

In the Oxygen XPath test window, "root/(foo|bar|mercury|venus)[last()]" got me
where I wanted to be, but alas, parentheses are not allowed in the @match for
the template.

Thanks!
Charles
