The data model within which an assertion is evaluated is comprised only of the element itself, not its siblings. You are looking at siblings.

Per the specification:

https://www.w3.org/TR/xmlschema11-1/#sec-cvc-assertion

I hope this helps.

Hi Folks,

Below is a sample XHTML document. Immediately following the <style> element is a comment. I want to ensure that the value in the comment starts with this string:

[if gte mso 9]><xml>

Using Oxygen, I ran the following XPath query (the <head> element is the context node):

*[local-name() eq 'style']/following-sibling::comment()[1]/starts-with(., '[if gte mso 9]>&lt;xml>')

The result of running the query is:

true()

Perfect!

Next, I put the query into an XML Schema 1.1 assert element:

<xs:assert test="*[local-name(.) eq 'style']/following-sibling::comment()[1]/starts-with(., '[if gte mso 9]>&lt;xml>')" />

When I validated the XHTML document against the XML Schema, I got this error:

Assertion evaluation ('*[local-name(.) eq 'style']/following-sibling::comment()[1]/starts-with(., '[if gte mso 9]><xml>')') for element 'head' on schema type 'headType' did not succeed.

Why does the XPath query work fine when run in Oxygen but fails when used in an XSD 1.1 assert element? /Roger

Here's the XHTML document:
