I've scoured google, but apparently none of the suggestions actually work.
I have the following. type of XPATH query
"SomeNode[SomeAttribute = 'abc's search'"
Now, I've tried doing this:
"SomeNode[SomeAttribute = 'abc@apos;s search'"
and I've tried
"SomeNode[SomeAttribute = 'abc@quot;s search'"
And neither one of these gives me a result.
Note, because of the structure and the way this XPATH is put together, I
would prefer to not have to use double quotes as the delimiters for the
search string, I'd like to keep it single quotes.
How to make this query find my node?

In what context are you using the XPath? If that is an XSLT stylesheet
then using entity references like ' or " might help but if you
have .NET code (e.g. C# or VB.NET) then using those XML entity
references is not possible.
As for that escape problem, it is ugly, XPath 1.0 itself does not have
any escape mechanism so you need to split strings e.g. C# string literal
to be passed to SelectSingleNod e looks like
@"SomeNode[@SomeAttribute = concat('abc', ""'"", 's search')]"

Oy... what a headache.
The problem with this approach is that I can't just escape the characters.
There is a ton of code that already assumes there are single quote
delimiters to the search string. All that would have to be changed.
Using the jscript XML object model this all works without a problem. And
yet, .NET can't implement an XML DOM that works half way decent.

I am not sure why you think it is a .NET issue. What exactly are you
doing with JScript and MSXML that you can't do with .NET and C# (or VB.NET)?

Querying a dom to locate certain nodes where a string literal has a single
quote in it.
This works perfectly in MSXML, as apparently that uses an XSL pattern query
(not that I really know exactly what that is), which is apparently more
flexible, and allows this to actually work.
..NET follows the XPATH 1.0 standard, which apparently isn't as useful,
meaning I can't have single quotes in literals when searching for nodes in a
DOM.

You want me to use the XSL as an XPATH expression?
I think concat on its own works fine. The problem is, like I said, I didn't
want to have to change the delimiters which are single quotes everywhere.
Which I would have to do, so the concat doesn't end up as a literal.
I expected to be able to do a replace in the search string to escape the
single quotes, so single quotes can remain the delimiters for the literal.
