Re: [xml-dev] Why is \/ invalid in a regular expression?
\n is newline \\ is \ what do you want \/ to stand for if it were valid?
the defined escapes are in the table here https://www.w3.org/TR/xmlschema-2/#nt-charClassEsc

Hi Folks,
The following simpleType is invalid:
<xs:simpleType name="test">
<xs:restriction base="xs:string">
<xs:pattern value="([A-Z\/]{2,4})" />
</xs:restriction>
</xs:simpleType>
Why is the simpleType invalid? Because the regex in the pattern facet is invalid.
Why is the regex invalid? Because a backslash preceding a forward slash is invalid, i.e., \/ is invalid.
Why is \/ invalid? I have no idea. Anyone know why?
