public Object getAt(int index)

Supports the subscript operator for a GPathResult.

 import groovy.util.slurpersupport.*
 def text = """
 <characterList>
   <character/>
   <character>
     <name>Gromit</name>
   </character>
 </characterList>"""

 GPathResult characterList = new XmlSlurper().parseText(text)

 assert characterList.character[1].name == 'Gromit'
 

Parameters:

index - an index

Returns:

the value at the given index

public Object getAt(IntRange range)

Supports the range subscript operator for a GPathResult.

 import groovy.util.slurpersupport.*
 def text = """
 <characterList>
   <character>Wallace</character>
   <character>Gromit</character>
   <character>Shaun</character>
 </characterList>"""

 GPathResult characterList = new XmlSlurper().parseText(text)

 assert characterList.character[1..2].join(',') == 'Gromit,Shaun'
 

Parameters:

range - a Range indicating the items to get

Returns:

a new list based on range borders

@Override public Object getAttribute(Object object, String attribute)

public Closure getBody()

Creates a Closure representing the body of this GPathResult.

Returns:

the body of this GPathResult, converted to a Closure

public Object getProperty(String property)

Returns the specified Property of this GPathResult.

Realizes the follow shortcuts:

• '..' for parent()
• '*' for children()
• '**' for depthFirst()
• '@' for attribute access

Parameters:

property - the Property to fetch

public boolean hasNext()

public boolean hasNext()

public boolean hasNext()

@Override public int hashCode()

public boolean isEmpty()

Returns true if the GPathResult is empty, i.e. if, and only if, size() is 0.

Returns:

true if the GPathResult is empty

public abstract Iterator iterator()

public Object leftShift(Object newValue)

Overloads the left shift operator to provide an easy way to lazily append Objects to this GPathResult.

Parameters:

newValue - the Object to append

Returns:

this

public List list()

Creates a list of objects representing this GPathResult.

Returns:

a list representing of this GPathResult

public String lookupNamespace(String prefix)

Returns the namespace mapped to the specified prefix.

Parameters:

prefix - the prefix lookup

Returns:

the namespace of the prefix

public String name()

Returns the name of this GPathResult.

Returns:

the name of this GPathResult

public Object next()

public Object next()

public Object next()

public abstract Iterator nodeIterator()

public GPathResult parent()

Returns as GPathResult with the parent nodes of the current GPathResult

Returns:

the parents GPathResult or this for the root

public abstract GPathResult parents()

Returns the parents of this GPathResult as a GPathResult. Warning: The subclasses of this package do not implement this method yet.

Returns:

the parents of this GPathResult

public Object plus(Object newValue)

Lazily adds the specified Object to this GPathResult.

Parameters:

newValue - the Object to add

Returns:

this

public GPathResult pop()

Returns the parent of this GPathResult. If this GPathResult has no parent the GPathResult itself is returned. This is no navigation in the XML tree. It is backtracking on the GPath expression chain. It is the behavior of parent() prior to 2.2.0. Backtracking on '..' actually goes down one level in the tree again. find() and findAll() are popped along with the level they have been applied to.

Returns:

the parent or this

public void putAt(int index, Object newValue)

Parameters:

index - an index

newValue - the value to put at the given index

public void remove()

public void remove()

public void remove()

protected abstract void replaceBody(Object newValue)

protected abstract void replaceNode(Closure newValue)
