This XQuery Module contains functions to perform validations against XML Schema and Document Type Declarations. This module has been introduced with Version 7.2.2.

All functions are preceded by the validate: prefix, which is linked to the statically declared http://basex.org/modules/validate namespace.

Functions

validate:xsd

Signatures	`validate:xsd($input as item()) as empty-sequence()` `validate:xsd($input as item(), $schema as item()) as empty-sequence()`
Summary	Validates the document specified by `$input`. Both `$input` and `$schema` may be an `xs:string`, containing the path to the resource, an `xs:string`, containing the resource in its string representation, or a `node()`, containing the resource itself. `$schema` can be used to specify the schema for validation. If no schema is given, `$input` is required to contain an `xsi:(noNamespace)schemaLocation` as defined in W3C XML Schema.
Exceptions	Todo
Examples	`validate:xsd('doc.xml', 'doc.xsd')` validates the document `doc.xm` against the specified schema `doc.xsd`. The following example demonstrates how a document can be validated against a schema without resorting to local or remote URIs: let $doc := <simple:root xmlns:simple='http://basex.org/simple'/> let $schema := <xs:schema xmlns:xs='http://www.w3.org/2001/XMLSchema' targetNamespace='http://basex.org/simple'> <xs:element name='root'/> </xs:schema> return validate:xsd($doc, $schema)

Signatures validate:dtd($input as item()) as empty-sequence()
validate:dtd($input as item(), $dtd as xs:string) as empty-sequence()

Example 1: Basic validation against a document containing a schema definition

Query:

validate:xsd($doc)
