I'm parsing some XML files where some elements have inner CDATA text (and must contain a non-null amount of non-whitespace) that contains newlines that are important to retain. I was attempting to write an XSD to validate this, but my initial attempt of .* as the restriction failed because, at least in the Python xmlschema library I was using, a "." does not match newlines.
How do I allow newlines in an XSD restriction?

The solution was to use "\S", which matches up against any non-whitespace and "\s", which matches up against any whitespace. The following indicates that this "script" element type must have at least one non-whitespace character in it that may be bracketed by any number of whitespace or non-whitespace characters:
<xs:simpleType name="script">
<xs:restriction base="xs:string">
<xs:whiteSpace value="preserve"/>
<xs:pattern value="[\s\S]*\S[\s\S]*"/>
</xs:restriction>
</xs:simpleType>
