Ah!
You are right!
Thanks Martin.

I need an XPath 2.0 expression for this:
Check that each comma in the <value>
element is escaped with a backslash.
Do you want that expression to return a boolean value of true or false?
Examples:
This is good:
<value>A\, B</value>
This is bad:
<value>A, B</value>
This is also bad, because one comma is escaped but the other is not:
<value>A\, B, C</value>
I created an XPath expression to see if the text is good:
tokenize(text(), ',')[position() lt last()][ends-with(., '\')]
I think that is correct. Is there a simpler XPath expression to solve
this?
Shouldn't the check rather be
every $token in tokenize(., ',')[position() lt last()] satisfies
ends-with($token, '\') ?
