public static XPath createXPath(String xpathExpression)
throws InvalidXPathException
createXPath parses an XPath expression and creates a new
XPath XPath instance using the singleton DocumentFactory.
xpathExpression - is the XPath expression to create
XPath instance
InvalidXPathException - if the XPath expression is invalid
public static XPath createXPath(String xpathExpression,
org.jaxen.VariableContext context)
throws InvalidXPathException
createXPath parses an XPath expression and creates a new
XPath XPath instance using the singleton DocumentFactory.
xpathExpression - is the XPath expression to createcontext - is the variable context to use when evaluating the XPath
XPath instance
InvalidXPathException - if the XPath expression is invalidpublic static NodeFilter createXPathFilter(String xpathFilterExpression)
createXPathFilter parses a NodeFilter from the given XPath
filter expression using the singleton DocumentFactory. XPath
filter expressions occur within XPath expressions such as
self::node()[ filterExpression ]
xpathFilterExpression - is the XPath filter expression to create
NodeFilter instancepublic static Pattern createPattern(String xpathPattern)
createPattern parses the given XPath expression to create
an XSLT style Patterninstance which can then be used in an XSLT
processing model.
xpathPattern - is the XPath pattern expression to create
Pattern instance
public static List selectNodes(String xpathFilterExpression,
List nodes)
selectNodes performs the given XPath expression on the
Listof Nodeinstances appending all the results together
into a single list.
xpathFilterExpression - is the XPath filter expression to evaluatenodes - is the list of nodes on which to evalute the XPath
public static List selectNodes(String xpathFilterExpression,
Node node)
selectNodes performs the given XPath expression on the
Listof Nodeinstances appending all the results together
into a single list.
xpathFilterExpression - is the XPath filter expression to evaluatenode - is the Node on which to evalute the XPath
public static void sort(List list,
String xpathExpression)
sort sorts the given List of Nodes using an XPath
expression as a Comparator.
list - is the list of Nodes to sortxpathExpression - is the XPath expression used for comparison
public static void sort(List list,
String expression,
boolean distinct)
sort sorts the given List of Nodes using an XPath
expression as a Comparatorand optionally removing
duplicates.
list - is the list of Nodes to sortexpression - is the XPath expression used for comparisondistinct - if true then duplicate values (using the sortXPath for
comparisions) will be removed from the List
public static Document parseText(String text)
throws DocumentException
parseText parses the given text as an XML document and
returns the newly created Document.
text - the XML text to be parsed
DocumentException - if the document could not be parsed
public static Element makeElement(Branch source,
String path)
makeElement
a helper method which navigates from the given Document or Element node to some Element using the path expression, creating any necessary elements along the way. For example the patha/b/c would
get the first child <a> element, which would be created if it did
not exist, then the next child <b> and so on until finally a
<c> element is returned.
source - is the Element or Document to start navigating frompath - is a simple path expression, seperated by '/' which denotes
the path from the source to the resulting element such as
a/b/c
