所有已实现的接口:

java.io.Serializable, java.lang.Cloneable, org.jdom.Parent

public class AnakiaElement
extends org.jdom.Element

A JDOM Element that is tailored for Anakia needs. It has selectNodes(String) method as well as a toString() that outputs the XML serialized form of the element. This way it acts in much the same way as a single-element NodeList would.

构造器

构造器和说明
AnakiaElement(java.lang.String name) This will create an AnakiaElement in no Namespace.
AnakiaElement(java.lang.String name, org.jdom.Namespace namespace) This will create a new AnakiaElement with the supplied (local) name, and define the Namespace to be used.

构造器详细资料

AnakiaElement

public AnakiaElement(java.lang.String name,
                     org.jdom.Namespace namespace)

This will create a new AnakiaElement with the supplied (local) name, and define the Namespace to be used. If the provided namespace is null, the element will have no namespace.

参数:

name - String name of element.

namespace - Namespace to put element in.

AnakiaElement

public AnakiaElement(java.lang.String name)

This will create an AnakiaElement in no Namespace.

参数:

name - String name of element.

AnakiaElement

public AnakiaElement(java.lang.String name,
                     java.lang.String uri)

This will create a new AnakiaElement with the supplied (local) name, and specifies the URI of the Namespace the Element should be in, resulting it being unprefixed (in the default namespace).

参数:

name - String name of element.

uri - String URI for Namespace element should be in.

AnakiaElement

public AnakiaElement(java.lang.String name,
                     java.lang.String prefix,
                     java.lang.String uri)

This will create a new AnakiaElement with the supplied (local) name, and specifies the prefix and URI of the Namespace the Element should be in.

参数:

name - String name of element.

prefix - The prefix of the element.

uri - String URI for Namespace element should be in.

方法详细资料

selectNodes

public NodeList selectNodes(java.lang.String xpathExpression)

Applies an XPath expression to this element and returns the resulting node list. In order for this method to work, your application must have access to werken.xpath library classes. The implementation does cache the parsed format of XPath expressions in a weak hash map, keyed by the string representation of the XPath expression. As the string object passed as the argument is usually kept in the parsed template, this ensures that each XPath expression is parsed only once during the lifetime of the template that first invoked it.

参数:

xpathExpression - the XPath expression you wish to apply

返回:

a NodeList representing the nodes that are the result of application of the XPath to the current element. It can be empty.

toString

public java.lang.String toString()

Returns the XML serialized form of this element, as produced by the default XMLOutputter.

覆盖:

toString 在类中 org.jdom.Element

返回:

The XML serialized form of this element, as produced by the default XMLOutputter.

getContent

public java.util.List getContent()

This returns the full content of the element as a NodeList which may contain objects of type String, Element, Comment, ProcessingInstruction, CDATA, and EntityRef. The List returned is "live" in document order and modifications to it affect the element's actual contents. Whitespace content is returned in its entirety.

指定者:

getContent 在接口中 org.jdom.Parent

覆盖:

getContent 在类中 org.jdom.Element

返回:

a List containing the mixed content of the element: may contain String, Element, Comment, ProcessingInstruction, CDATA, and EntityRef objects.

getChildren

public java.util.List getChildren()

This returns a NodeList of all the child elements nested directly (one level deep) within this element, as Element objects. If this target element has no nested elements, an empty List is returned. The returned list is "live" in document order and changes to it affect the element's actual contents.

This performs no recursion, so elements nested two levels deep would have to be obtained with:

 
   Iterator itr = currentElement.getChildren().iterator();
   while (itr.hasNext()) {
     Element oneLevelDeep = (Element)nestedElements.next();
     List twoLevelsDeep = oneLevelDeep.getChildren();
     // Do something with these children
   }
 
 

覆盖:

getChildren 在类中 org.jdom.Element

返回:

list of child Element objects for this element

getChildren

public java.util.List getChildren(java.lang.String name)

This returns a NodeList of all the child elements nested directly (one level deep) within this element with the given local name and belonging to no namespace, returned as Element objects. If this target element has no nested elements with the given name outside a namespace, an empty List is returned. The returned list is "live" in document order and changes to it affect the element's actual contents.

Please see the notes for getChildren() for a code example.

覆盖:

getChildren 在类中 org.jdom.Element

参数:

name - local name for the children to match

返回:

all matching child elements

getChildren

public java.util.List getChildren(java.lang.String name,
                                  org.jdom.Namespace ns)

This returns a NodeList of all the child elements nested directly (one level deep) within this element with the given local name and belonging to the given Namespace, returned as Element objects. If this target element has no nested elements with the given name in the given Namespace, an empty List is returned. The returned list is "live" in document order and changes to it affect the element's actual contents.

Please see the notes for getChildren() for a code example.

覆盖:

getChildren 在类中 org.jdom.Element

参数:

name - local name for the children to match

ns - Namespace to search within

返回:

all matching child elements

getAttributes

public java.util.List getAttributes()

This returns the complete set of attributes for this element, as a NodeList of Attribute objects in no particular order, or an empty list if there are none. The returned list is "live" and changes to it affect the element's actual attributes.

覆盖:

getAttributes 在类中 org.jdom.Element

返回:

attributes for the element
