Method Detail

getAttributes

public static List getAttributes(Element el)

Returns a list of attributes of an element. Returns an empty list if the element has no attributes. Does not include namespace declarations.

Parameters:

el - Element whose attributes are returned

Returns:

the List of Attr

getAttribute

public static String getAttribute(Element el,
                                  String attrName)

Returns the value of an attribute of an element. Returns null if the attribute is not found (whereas Element.getAttribute returns "" if an attrib is not found). This method should be used for elements that support extension attributes because it does not track unexpected attributes.

Parameters:

el - Element whose attrib is looked for

attrName - name of attribute to look for

Returns:

the attribute value

getAttribute

public static String getAttribute(Element el,
                                  String attrName,
                                  List remainingAttrs)

Returns the value of an attribute of an element. Returns null if the attribute is not found (whereas Element.getAttribute returns "" if an attrib is not found). This method should be used for elements that do not support extension attributes because it tracks the element's remaining attributes so that eventually any unexpected attributes can be identified.

Parameters:

el - Element whose attrib is looked for

attrName - name of attribute to look for

remainingAttrs - List of remaining attributes

Returns:

the attribute value

getAttributeNS

public static String getAttributeNS(Element el,
                                    String namespaceURI,
                                    String localPart)

Returns the value of an attribute of an element. Returns null if the attribute is not found (whereas Element.getAttributeNS returns "" if an attrib is not found).

Parameters:

el - Element whose attrib is looked for

namespaceURI - namespace URI of attribute to look for

localPart - local part of attribute to look for

Returns:

the attribute value

getChildCharacterData

public static String getChildCharacterData(Element parentEl)

Concat all the text and cdata node children of this elem and return the resulting text.

Parameters:

parentEl - the element whose cdata/text node values are to be combined.

Returns:

the concatanated string.

getFirstChildElement

public static Element getFirstChildElement(Element elem)

Return the first child element of the given element. Null if no children are found.

Parameters:

elem - Element whose child is to be returned

Returns:

the first child element.

getNextSiblingElement

public static Element getNextSiblingElement(Element elem)

Return the next sibling element of the given element. Null if no more sibling elements are found.

Parameters:

elem - Element whose sibling element is to be returned

Returns:

the next sibling element.

findChildElementWithAttribute

public static Element findChildElementWithAttribute(Element elem,
                                                    String attrName,
                                                    String attrValue)

Return the first child element of the given element which has the given attribute with the given value.

Parameters:

elem - the element whose children are to be searched

attrName - the attrib that must be present

attrValue - the desired value of the attribute

Returns:

the first matching child element.

countKids

public static int countKids(Element elem,
                            short nodeType)

Count number of children of a certain type of the given element.

Parameters:

elem - the element whose kids are to be counted

Returns:

the number of matching kids.

getNamespaceURIFromPrefix

public static String getNamespaceURIFromPrefix(Node context,
                                               String prefix)

Given a prefix and a node, return the namespace URI that the prefix has been associated with. This method is useful in resolving the namespace URI of attribute values which are being interpreted as QNames. If prefix is null, this method will return the default namespace.

Parameters:

context - the starting node (looks up recursively from here)

prefix - the prefix to find an xmlns:prefix=uri for

Returns:

the namespace URI or null if not found
