[Java] Class XmlSlurper
- groovy.util.XmlSlurper
@Deprecated public class XmlSlurper extends DefaultHandler
Parse XML into a document tree that may be traversed similar to XPath expressions. For example:
def rootNode = new XmlSlurper().parseText( '<root><one a1="uno!"/><two>Some text!</two></root>' ) assert rootNode.name() == 'root' assert rootNode.one[0].@a1 == 'uno!' assert rootNode.two.text() == 'Some text!' rootNode.children().each { assert it.name() in ['one','two'] }
Note that in some cases, a 'selector' expression may not resolve to a single node. For example:
def rootNode = new XmlSlurper().parseText( '''<root> <a>one!</a> <a>two!</a> </root>''' ) assert rootNode.a.size() == 2 rootNode.a.each { assert it.text() in ['one!','two!'] }

- use XmlSlurper

- Parameters:
-
validating
-true
if the parser should validate documents as they are parsed; false otherwise. -
namespaceAware
-true
if the parser should provide support for XML namespaces;false
otherwise.

Method Detail
public void characters(char[] ch, int start, int length)
public void endDocument()
public void endElement(String namespaceURI, String localName, String qName)
public DTDHandler getDTDHandler()
public GPathResult getDocument()
- Returns:
- The GPathResult instance created by consuming a stream of SAX events Note if one of the parse methods has been called then this returns null Note if this is called more than once all calls after the first will return null
public EntityResolver getEntityResolver()
public ErrorHandler getErrorHandler()
public boolean getFeature(String uri)
public Object getProperty(String uri)
public void ignorableWhitespace(char[] buffer, int start, int len)
public boolean isKeepIgnorableWhitespace()
- Returns:
- true if ignorable whitespace is kept
public GPathResult parse(InputSource input)
Parse the content of the specified input source into a GPathResult object
