Two functions in this specification, fn:analyze-string
and
fn:json-to-xml
, produce results in the form of an XDM node tree that must conform
to a specified schema. In both cases the elements in the result are in the namespace
http://www.w3.org/2005/xpath-functions
, which is therefore the target namespace
of the relevant schema document.
The schema for this namespace is organized as three schema documents. The first is a simple umbrella document that includes the other two. A copy can be found at xpath-functions.xsd:
<?xml version="1.0" encoding="UTF-8"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" targetNamespace="http://www.w3.org/2005/xpath-functions"> <!-- * This is a schema for the namespace http://www.w3.org/2005/xpath-functions * * The schema is made available under the terms of the W3C software notice and license * at http://www.w3.org/Consortium/Legal/copyright-software-19980720 * * The schema includes two schema documents, containing definitions of the structure * of the results of the fn:analyze-string and fn:json-to-xml functions respectively. * --> <xs:include schemaLocation="analyze-string.xsd"/> <xs:include schemaLocation="schema-for-json.xsd"/> </xs:schema>
fn:analyze-string
This schema describes the output of the function fn:analyze-string
.
The schema is reproduced below, and can also be found in analyze-string.xsd:
<?xml version="1.0" encoding="UTF-8"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.w3.org/2005/xpath-functions" xmlns:fn="http://www.w3.org/2005/xpath-functions" elementFormDefault="qualified"> <!-- * This is a schema for the XML representation of JSON used as the target for the * function fn:analyze-string() * * The schema is made available under the terms of the W3C software notice and license * at http://www.w3.org/Consortium/Legal/copyright-software-19980720 * --> <xs:element name="analyze-string-result" type="fn:analyze-string-result-type"/> <xs:element name="match" type="fn:match-type"/> <xs:element name="non-match" type="xs:string"/> <xs:element name="group" type="fn:group-type"/> <xs:complexType name="analyze-string-result-type" mixed="true"> <xs:choice minOccurs="0" maxOccurs="unbounded"> <xs:element ref="fn:match"/> <xs:element ref="fn:non-match"/> </xs:choice> </xs:complexType> <xs:complexType name="match-type" mixed="true"> <xs:sequence> <xs:element ref="fn:group" minOccurs="0" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> <xs:complexType name="group-type" mixed="true"> <xs:sequence> <xs:element ref="fn:group" minOccurs="0" maxOccurs="unbounded"/> </xs:sequence> <xs:attribute name="nr" type="xs:positiveInteger"/> </xs:complexType> </xs:schema>
fn:json-to-xml
This schema describes the output of the function fn:json-to-xml
, and the input to the
function fn:xml-to-json
.
The schema is reproduced below, and can also be found in schema-for-json.xsd:
