## Classes

QAbstractMessageHandler | Callback interface for handling messages
QAbstractUriResolver | Callback interface for resolving Uniform Resource Identifiers. A Uniform Resource Identifier (URI) is a string that uniquely identifies a resource. URIs are versatile global identifiers. It is often useful to transform a URI that identifies something logical into a URI that locates something physical (a URL), or to simply map a URI to a different URI. QAbstractUriResolver::resolve() provides this functionality
QAbstractXmlNodeModel | Abstract base class for modeling non-XML data to look like XML for QXmlQuery
QXmlItem | Contains either an XML node or an atomic value
QXmlNodeModelIndex | Identifies a node in an XML node model subclassed from QAbstractXmlNodeModel
QAbstractXmlReceiver | Callback interface for transforming the output of a QXmlQuery
QSimpleXmlNodeModel | Implementation of QAbstractXmlNodeModel sufficient for many common cases
QSourceLocation | Identifies a location in a resource by URI, line, and column
QXmlFormatter | Implementation of QXmlSerializer for transforming XQuery output into formatted XML
QXmlName | Represents the name of an XML node, in an efficient, namespace-aware way. QXmlName represents the name of an XML node in a way that is both efficient and safe for comparing names. Normally, an XML node represents an XML element or attribute, but QXmlName can also represent the names of other kinds of nodes, e.g., QAbstractXmlReceiver::processingInstruction() and QAbstractXmlReceiver::namespaceBinding()
QXmlNamePool | Table of shared strings referenced by instances of QXmlName
QXmlQuery | Performs XQueries on XML data, or on non-XML data modeled to look like XML
QXmlResultItems | Iterates through the results of evaluating an XQuery in QXmlQuery
QXmlSchema | Loading and validation of a W3C XML Schema
QXmlSchemaValidator | Validates XML instance documents against a W3C XML Schema
QXmlSerializer | Implementation of QAbstractXmlReceiver for transforming XQuery output into unformatted XML

## Detailed Description

The Qt XML Patterns module provides support for XPath, XQuery, XSLT and XML Schema validation.

To include the definitions of the module's classes, use the following directive:

      #include <QtXmlPatterns>

To link against the module, add this line to your qmake `.pro` file:
