XPATH question

[doncristiano]

Hello

I have one question regarding an XPATH expression . Code:

Code: Select all

<?xml version="1.1" encoding="UTF-8"?>

<foo:root xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:foo="http://foo"  foo:schemaLocation="http://foo file:/c:/c1.xsd"/>

and schema:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://foo" xmlns:foo = "http://foo" elementFormDefault="qualified">

    <xs:element name="root"/>   

    <xs:simpleType name="range">

        <xs:restriction base="xs:integer">

            <xs:minInclusive value="17"/>

            <xs:maxInclusive value="18"/>

        </xs:restriction>

    </xs:simpleType>

</xs:schema>

When I'm executing this XPath:

Code: Select all

17 instance of foo:range

I get the following error

Code: Select all

net.sf.saxon.trans.StaticError: XPath syntax error at char 17 (...). There is no imported schema for namespace http://foo

I do not know where is the mistake. Can you help me please?
Thanks.

Hi,

I believe you can't use a simple type name after 'instance of' only an atomic type or a kind test:
http://www.w3.org/TR/xpath20/#id-instance-of

By the way is your XML instance another schema in itself? If not, you might have a mistake here.
I see you have another XML schema namespace declaration in the XML file:

Code: Select all

xmlns:xs="http://www.w3.org/2001/XMLSchema"

Usually an XML instance has the XML instance namespace declaration and the schema location, like this:

Code: Select all

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://foo file:/c:/c1.xsd"
