This is not really question about Stylus Studio. Apologies in advance if it is inappropriate.

I want to define a Simple Type based on xsd:string so that the valid value MUST start with / (easy part) and DOES NOT contain word param and xyz.

So /data/subdir/test.jsp is valid.

And
/data/subdir/test.jsp?param=10&xyz=20
/data/subdir/test.jsp?param=10
/data/subdir/test.jsp?xyz=20

are all invalid.

Thanks

It sounds like you need to set up a Regex pattern restriction (i.e. use xsd:pattern).
A regex of "/.*" will only accept strings that start with a "/".
If you extend that to "/.*(param|xyz).*" that will require a string that starts with a "/" and must contain either "param" or "xyz" within it. The "^" metacharacter should be able to negate that for you, but unfortunately I can't remember how to get it just right.

If I understood correctly you want to refuse urls with parameters.

Assuming this document is the input

{?xml version="1.0"?}
{root
xsi:noNamespaceSchemaLocation="myurl.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"}

{!--valid--}
{url}/a/test.jsp{/url}

{!--invalid--}
{url}a/test.jsp{/url}
{url}/data/subdir/test.jsp?param=10&xyz=20{/ur}

{/root}

The following schema should do it

-- myurl.xsd --

{?xml version="1.0"?}
{xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"}
{xsd:simpleType name="MyUrl"}
{xsd:restriction base="xsd:string"}
{xsd:pattern value="/[\p{N}\p{L}\./]*.jsp"/}
{/xsd:restriction}
{/xsd:simpleType}
{xsd:element name="root"}
{xsd:complexType}
{xsd:sequence maxOccurs="unbounded"}
{xsd:element name="url" type="MyUrl"/}
{/xsd:sequence}
{/xsd:complexType}
{/xsd:element}
{/xsd:schema}

You may interested in this alternative solution using Schematron[1]

{?xml version="1.0"?}
{schema xmlns="http://www.ascc.net/xml/schematron"}
{pattern name="param is forbidden"}
{rule context="/root/url"}
{assert test="starts-with(., '/')"}
Text in element "" must start with /
{/assert}
{assert test="not(contains(.,'param'))"}
Text in element "" must not contain param
{/assert}
{/rule}
{/pattern}
{/schema}

Schematron works asserting Xpath expressions.
It is implemented as a stylesheet[2]that takes in input a schematron
schema and generates a stylesheet as ouput.
The generated stylesheet is used to validate your documents.

Thanks to both of you for the reply.

Lee, I ran into same problem. I don't know how to negate.

Ivan, the schematron version looks more accurate to what I need. But I cannot use that unless every validator supports that. Our system uses different validators at different stages. So I would prefer to stick to just schema syntax.

The first version relies on the fact that url ends with jsp extension. Actually I want to ensure certain parameters are not authored in a url. But there could be some others that are allowed. Sorry for not stating my problem correctly.
