Sorry, brain leak -- You can't have two element children of the root
node. Thought about that much too mechanically.
The root node is _defined_ as having zero or one element children.
If you meant the document node -- the single element child of the root
node --
then see the amended version below.
If you meant the root node, you can't do that.
If that means that what you want is to stick everything else inside your
known node a, or vice-versa, that's a bit different.

I would love to know how to (using XSL) insert a pre-determined node a
(with children b and c) as a child of the root node of an arbitrary
XML. I
know how to apply the XSL once I've got it. I just need help with
the XSL.
All the examples I'm finding online assume a pre-determined XML,
which I
cannot in this case.
[snip illustrative abstract example]
Most importantly, please note that any solutions with hard-coded
references
to any node names (other than those I want to insert) are not usable
for
me. I have no control over the schema of the XML into which I'm
sticking
these other nodes. I know only that it's a valid XML file and the
root has
at least one child. The above example is a purely made up example
designed
to illustrate the question.
You can do this with two templates, at least if I understand the
question:
<!-- Our old friend the identity transform -->
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>
<!-- match the first element child of the document node -->
^^^^^^^^
You can't have two element children of the root node; the root node is
_defined_
as having only one element child.
<xsl:template match="/*/*[1]">
^^^^^^^
<element> Your fixed content goes here as literal result elements
</element>
<!-- but don't lose the former first element child of the root node
-->
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>
There is only one child of the root node, but you still can match it. This
modification of your original (along with the identity template) works
nicely for me with XSL1 in xalan. The advantage of matching the root
element is that there might not be any children.
I think you'll need to write your fixed content in the copy - and don't
forget to process the attributes before you write any children
<!-- match the first element child of the root node -->
<xsl:template match="/*[1]">
<!-- but don't lose the former first element child of the root node -->
<xsl:copy>
<xsl:apply-templates select="@*"/>
<element> Your fixed content goes here as literal result elements
</element>
<xsl:apply-templates select="node()"/>
</xsl:copy>
</xsl:template>
