This XQuery Module contains functions to perform validations against DTDs, XML Schema and RelaxNG. The documentation further describes how to use Schematron validation with BaseX.
Conventions[edit]
All functions and errors in this module are assigned to the http://basex.org/modules/validate
namespace, which is statically bound to the validate
prefix.
DTD Validation[edit]
Checks whether an XML document validates against a DTD. The input document can be specified as:
xs:string
, representing a URI (relative URIs will always be resolved against the static base URI of the query),xs:string
, representing the resource in its string representation, ornode()
, representing the resource itself.
If no DTD is supplied in a function, the XML document is expected to contain an embedded DTD doctype declaration.
validate:dtd[edit]
Signature | validate:dtd( $input as item(), $schema as xs:string? := () ) as empty-sequence() |
Summary | Validates the XML $input document against a $schema and returns an empty sequence or an error.
|
Errors | error : the validation fails.init : the validation process cannot be started.not-found : no DTD validator is available.
|
Examples |
try {
let $doc := <invalid/>
let $schema := '<!ELEMENT root (#PCDATA)>'
return validate:dtd($doc, $schema)
} catch validate:error {
'DTD Validation failed.'
}
|
validate:dtd-info[edit]
Signature | validate:dtd-info( $input as item(), $schema as xs:string? := () ) as xs:string* |
Summary | Validates the XML $input document against a $schema and returns warnings, errors and fatal errors in a string sequence.
|
Errors | init : the validation process cannot be started.not-found : no DTD validator is available.
|
Examples |
|
validate:dtd-report[edit]
Signature | validate:dtd-report( $input as item(), $schema as xs:string? := () ) as element(report) |
Summary | Validates the XML $input document against a $schema and returns warnings, errors and fatal errors as XML.
|
Errors | init : the validation process cannot be started.not-found : no DTD validator is available.
|
Examples |
<report>
<status>invalid</status>
<message level="Error" line="2" column="11">Element type "invalid" must be declared.</message>
</report>
|
XML Schema Validation[edit]
Checks whether an XML document validates against an XML Schema. The input document and the schema can be specified as:
xs:string
, containing the path to the resource,xs:string
, containing the resource in its string representation, ornode()
, containing the resource itself.
If no schema is given, the input is expected to contain an xsi:(noNamespace)schemaLocation
attribute, as defined in W3C XML Schema.
Different XML Schema processors are supported:
- By default, the Java implementation of XML Schema 1.0 is used (it is based on an old version of Apache Xerces).
- The latest version of Xerces2 provides implementations of XML Schema 1.0 and 1.1. The processor will be applied if you download one of the binary distributions and copy the following libraries to the
lib/custom
directory of the full distribution of BaseX:org.eclipse.wst.xml.xpath2.processor_1.2.0.jar
cupv10k-runtime.jar
xercesImpl.jar
xml-apis.jar
- Saxon Enterprise Edition will be used if you download the ZIP release and if you copy
saxon9ee.jar
and a valid license key to the classpath.
validate:xsd[edit]
Updated with Version 11: caching feature added.
Signature | validate:xsd( $input as item(), $schema as item()? := (), $options as map(*)? := map { } ) as empty-sequence() |
Summary | Validates the XML $input document against a $schema . The supported $options are:
|
Errors | error : the validation fails.init : the validation process cannot be started.not-found : no XML Schema validator is available.
|
Examples |
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)
for $city in db:get('cities')
return validate:xsd($city, 'city.xsd',
map { 'http://javax.xml.XMLConstants/feature/secure-processing': true() }
)
|
validate:xsd-info[edit]
Signature | validate:xsd-info( $input as item(), $schema as item()? := (), $options as map(*)? := map { } ) as xs:string* |
Summary | Validates the XML $input document against a $schema and returns warnings, errors and fatal errors in a string sequence. See validate:xsd for more information of the $options parameter.
|
Errors | init : the validation process cannot be started.not-found : no XML Schema validator is available.
|
validate:xsd-report[edit]
Signature | validate:xsd-report( $input as item(), $schema as xs:string? := (), $options as map(*) := map { } ) as element(report) |
Summary | Validates the XML $input document against a $schema and returns warnings, errors and fatal errors as XML. See validate:xsd for more information of the $options parameter.
|
Errors | init : the validation process cannot be started.not-found : no XML Schema validator is available.
|
validate:xsd-processor[edit]
Signature | validate:xsd-processor() as xs:string |
Summary | Returns the name of the applied XSD processor. |
validate:xsd-version[edit]
Signature | validate:xsd-version() as xs:string |
Summary | Returns the supported version of XSD Schema. |
RelaxNG Validation[edit]
Checks whether an XML document validates against a RelaxNG schema. The input document and the schema can be specified as:
xs:string
, containing the path to the resource,xs:string
, containing the resource in its string representation, ornode()
, containing the resource itself.
RelaxNG validation will be available if Jing exists in the classpath. The latest version, jing-20091111.jar
, is included in the full distributions of BaseX. As Jing additionally supports NVDL validation, you can also use the functions to validate the input against NVDL schemas.
validate:rng[edit]
Signature | validate:rng( $input as item(), $schema as item(), $compact as xs:boolean? := map { } ) as empty-sequence() |
Summary | Validates the XML $input document against a $schema , using the XML or $compact notation.
|
Errors | error : the validation fails.init : the validation process cannot be started.not-found : the RelaxNG validator is not available.
|
Examples |
|
validate:rng-info[edit]
Signature | validate:rng-info( $input as item(), $schema as item(), $compact as xs:boolean? := map { } ) as xs:string* |
Summary | Validates the XML $input document against a $schema , using the XML or $compact notation, and returns warnings, errors and fatal errors in a string sequence.
|
Errors | init : the validation process cannot be started.not-found : the RelaxNG validator is not available.
|
validate:rng-report[edit]

|
Errors | init : the validation process cannot be started.not-found : The RelaxNG validator is not available.
|
Schematron Validation[edit]
If you want to use Schematron for validating documents, install Vincent Lizzi’s excellent 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";
let $sch := schematron:compile(doc('rules.sch'))
let $svrl := schematron:validate(doc('document.xml'), $sch)
return (
schematron:is-valid($svrl),
for $message in schematron:messages($svrl)
return concat(schematron:message-level($message), ': ', schematron:message-description($message))
)
Errors[edit]
Code | Description |
---|---|
error
|
The document cannot be validated against the specified schema. |
init
|
The validation cannot be started. |
not-found
|
No validator is available. |
