Changes

* {{Code|validate:dtd('doc.xml', 'doc.dtd')}} validates the document {{Code|doc.xml}} against the specified DTD file {{Code|doc.dtd}}.

* The following example validates an invalid document against a DTD, which is specified as string:

try {

let $doc := <invalid/>

'DTD Validation failed.'

}

|}

|

* <code>validate:dtd-report(<invalid/>, '<!ELEMENT root (#PCDATA)>')</code> returns:

<report>

<status>invalid</status>

<message level="Error" line="2" column="11">Element type "invalid" must be declared.</message>

</report>

|}

|

* Pass on document and schema as nodes:

let $doc := <simple:root xmlns:simple='http://basex.org/simple'/>

let $schema :=

</xs:schema>

return validate:xsd($doc, $schema)

* Validate all documents of a database against the specified schema, using the supplied feature:

for $city in db:open('cities')

return validate:xsd($city, 'city.xsd',

map { 'http://javax.xml.XMLConstants/feature/secure-processing': true() }

)

|}

If you want to use Schematron for validating documents, simply install Vincent Lizzi’s excellent [https://github.com/Schematron/schematron-basex Schematron XQuery Module for BaseX]:

repo:install('https://github.com/Schematron/schematron-basex/raw/master/dist/schematron-basex-1.2.xar')

The following query illustrates how documents are validated. It is directly taken from the GitHub project:

import module namespace schematron = "http://github.com/Schematron/schematron-basex";

return concat(schematron:message-level($message), ': ', schematron:message-description($message))

)
