public final class XPathMatcher
extends java.lang.Object
An XPath matcher. Implements the restricted subset of XPath as defined
by the XML Schema.
XSElementOrAttrRef[] | match(XSElement startingNode) - Return the elements and attributes matched by this xpath when applied
from the specified starting node.
|
void | match(XSElement startingNode, Set matches) - Return the elements and attributes matched by this xpath when applied
from the specified starting node.
|
static XSElementOrAttrRef[][] | match(XsTKeybase keybase, XSElement startingNode) - Matches every element and attribute referenced by the specified
keybase.
|
static XPathMatcher | parse(Locator locator, String xpath, boolean elementsOnly) - Create an XPathMatcher.

match
public XSElementOrAttrRef[] match(XSElement startingNode)
throws SAXException
Return the elements and attributes matched by this xpath when applied
from the specified starting node.
match
public void match(XSElement startingNode,
Set matches)
throws SAXException
Return the elements and attributes matched by this xpath when applied
from the specified starting node.
match
public static XSElementOrAttrRef[][] match(XsTKeybase keybase,
XSElement startingNode)
throws SAXException
Matches every element and attribute referenced by the specified
keybase.
The result is a two dimensional array, the first dimension corresponds to
each xs:field used to declare the constraint. The second dimension is
for each 'or' used within the fields xpath query.
Only tags and attributes that were matched by the xpath will be in the
result, any xpath that fails to match anything will not be stored
in this array.
parse
public static XPathMatcher parse(Locator locator,
String xpath,
boolean elementsOnly)
throws SAXException
Create an XPathMatcher. Parses a string holding a restricted subset
of XPath and returns an object that knows how to walk XSElement
objects based on that XPath.
elementsOnly
- True if the xpath is not allowed to match attributes.
