Class XMLValidateTask

public class XMLValidateTask extends Task

Checks XML files are valid (or only well formed). The task uses the SAX2 parser implementation provided by JAXP by default (probably the one that is used by Ant itself), but one can specify any SAX1/2 parser if needed.

Nested Class Summary
class	XMLValidateTask.Attribute The class to create to set a feature of the parser.
class	XMLValidateTask.Property A Parser property.
protected class	XMLValidateTask.ValidatorErrorHandler ValidatorErrorHandler role : log SAX parse exceptions, remember if an error occurred

Field Summary
protected Path	classpath
protected XMLValidateTask.ValidatorErrorHandler	errorHandler
protected boolean	failOnError
protected File	file file to be validated
protected Vector	filesets sets of file to be validated
protected static String	INIT_FAILED_MSG
protected boolean	lenient
protected String	readerClassName
protected boolean	warn
protected XMLReader	xmlReader the parser is viewed as a SAX2 XMLReader.

Method Summary
void	addConfiguredXMLCatalog(XMLCatalog catalog) add an XMLCatalog as a nested element; optional.
void	addFileset(FileSet set) specify a set of file to be checked
XMLValidateTask.Attribute	createAttribute() Add an attribute nested element.
Path	createClasspath()
DTDLocation	createDTD() Create a DTD location record; optional.
XMLValidateTask.Property	createProperty() Creates a property.
void	execute() execute the task
protected EntityResolver	getEntityResolver() accessor to the xmlCatalog used in the task
void	init() Called by the project to let the task initialize properly.
void	setClassName(String className) Specify the class name of the SAX parser to be used. (optional)
void	setClasspath(Path classpath) Specify the classpath to be searched to load the parser (optional)
void	setClasspathRef(Reference r) Where to find the parser class; optional.
void	setFailOnError(boolean fail) Specify how parser error are to be handled.
void	setFile(File file) specify the file to be checked; optional.
void	setLenient(boolean bool) Specify whether the parser should be validating.
void	setWarn(boolean bool) Specify how parser error are to be handled.

Field Detail

classpath

protected Path classpath

errorHandler

protected XMLValidateTask.ValidatorErrorHandler errorHandler

failOnError

protected boolean failOnError

file

protected File file

file to be validated

filesets

protected Vector filesets

sets of file to be validated

INIT_FAILED_MSG

protected static final String INIT_FAILED_MSG

lenient

protected boolean lenient

readerClassName

protected String readerClassName

warn

protected boolean warn

xmlReader

protected XMLReader xmlReader

the parser is viewed as a SAX2 XMLReader. If a SAX1 parser is specified, it's wrapped in an adapter that make it behave as a XMLReader. a more 'standard' way of doing this would be to use the JAXP1.1 SAXParser interface.

Method Detail

addConfiguredXMLCatalog

public void addConfiguredXMLCatalog(XMLCatalog catalog)

add an XMLCatalog as a nested element; optional.

Parameters: catalog XMLCatalog to use

addFileset

public void addFileset(FileSet set)

specify a set of file to be checked

Parameters: set the fileset to check

createAttribute

public XMLValidateTask.Attribute createAttribute()

Add an attribute nested element. This is used for setting arbitrary features of the SAX parser. Valid attributes include

Returns: attribute created

Since: ant1.6

createClasspath

public Path createClasspath()

Returns: the classpath created

createDTD

public DTDLocation createDTD()

Create a DTD location record; optional. This stores the location of a DTD. The DTD is identified by its public Id.

Returns: created DTD location

createProperty

public XMLValidateTask.Property createProperty()

Creates a property.

Returns: a property.

Since: ant 1.6.2

execute

public void execute()

execute the task

Throws: BuildException if failonerror is true and an error happens

getEntityResolver

protected EntityResolver getEntityResolver()

accessor to the xmlCatalog used in the task

Returns: xmlCatalog reference

init

public void init()

Called by the project to let the task initialize properly.

Throws: BuildException if something goes wrong with the build

setClassName

public void setClassName(String className)

Specify the class name of the SAX parser to be used. (optional)

Parameters: className should be an implementation of SAX2 org.xml.sax.XMLReader or SAX2 org.xml.sax.Parser.

if className is an implementation of org.xml.sax.Parser, {@link #setLenient(boolean)}, will be ignored.

if not set, the default will be used.

See Also: org.xml.sax.XMLReader org.xml.sax.Parser

setClasspath

public void setClasspath(Path classpath)

Specify the classpath to be searched to load the parser (optional)

Parameters: classpath the classpath to load the parser

setClasspathRef

public void setClasspathRef(Reference r)

Where to find the parser class; optional.

Parameters: r reference to a classpath defined elsewhere

setFailOnError

public void setFailOnError(boolean fail)

Specify how parser error are to be handled. Optional, default is true.

If set to true (default), throw a buildException if the parser yields an error.

Parameters: fail if set to false do not fail on error

setFile

public void setFile(File file)

specify the file to be checked; optional.

Parameters: file the file to be checked

setLenient

public void setLenient(boolean bool)

Specify whether the parser should be validating. Default is true.

If set to false, the validation will fail only if the parsed document is not well formed XML.

this option is ignored if the specified class with {@link #setClassName(String)} is not a SAX2 XMLReader.

Parameters: bool if set to false only fail on malformed XML

setWarn

public void setWarn(boolean bool)

Specify how parser error are to be handled.

If set to true (default), log a warn message for each SAX warn event.

Parameters: bool if set to false do not send warnings
