Class XMLValidateTask

    java.lang.Object
      org.apache.tools.ant.ProjectComponent
          org.apache.tools.ant.Task
              org.apache.tools.ant.taskdefs.optional.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

Field Detail

### INIT_FAILED_MSG

    protected static java.lang.String INIT_FAILED_MSG

### failOnError

    protected boolean failOnError

### warn

    protected boolean warn

### lenient

    protected boolean lenient

### readerClassName

    protected java.lang.String readerClassName

### file

    protected java.io.File file

### filesets

    protected java.util.Vector filesets

### classpath

    protected Path classpath

### xmlReader

    protected org.xml.sax.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.

### errorHandler

    protected XMLValidateTask.ValidatorErrorHandler errorHandler

### features

    protected java.util.Hashtable features

Constructor Detail

### XMLValidateTask

    public XMLValidateTask()

Method Detail

### setFailOnError

    public void setFailOnError(boolean fail)

  Specify how parser error are to be handled; optional, default=true

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

### setWarn

    public void setWarn(boolean bool)

  Specify how parser error are to be handled.

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

### 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 `setClassName(String)` is not a SAX2 XMLReader.

### setClassName

    public void setClassName(java.lang.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`, `setLenient(boolean)`, will be ignored.

    if not set, the default `#DEFAULT_XML_READER_CLASSNAME` will be used.

  See Also:
    `XMLReader`, `Parser`

### setClasspath

    public void setClasspath(Path classpath)

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

### createClasspath

    public Path createClasspath()

  See Also:
    `setClasspath(org.apache.tools.ant.types.Path)`

### setClasspathRef

    public void setClasspathRef(Reference r)

  Where to find the parser class; optional.

  See Also:
    `setClasspath(org.apache.tools.ant.types.Path)`

### setFile

    public void setFile(java.io.File file)

  specify the file to be checked; optional.

### addConfiguredXMLCatalog

    public void addConfiguredXMLCatalog(XMLCatalog catalog)

  add an XMLCatalog as a nested element; optional.

### addFileset

    public void addFileset(FileSet set)

  specify a set of file to be checked

### init

    public void init()
              throws BuildException

  Description copied from class: `Task`
  Called by the project to let the task initialize properly. The default implementation is a no-op.

  Overrides:
    `init` in class `Task`
  Throws:
    `BuildException` - if someting goes wrong with the build

### 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.

### getEntityResolver

    protected org.xml.sax.EntityResolver getEntityResolver()

### execute

    public void execute()
                 throws BuildException

  Description copied from class: `Task`
  Called by the project to let the task do its work. This method may be called more than once, if the task is invoked more than once. For example, if target1 and target2 both depend on target3, then running "ant target1 target2" will run all tasks in target3 twice.

  Overrides:
    `execute` in class `Task`
  Throws:
    `BuildException` - if something goes wrong with the build
