boolean | isFragmentResolved() - Returns true if the XPointer expression resolves to the current resource fragment
or Node which is part of the input resource being streamed else returns false.
|
boolean | isXPointerResolved() - Returns true if the XPointer expression resolves any subresource of the
input resource.
|
void | parseXPointer(String xpointer) - Parses an XPointer expression.
|
boolean | resolveXPointer(org.apache.xerces.xni.QName element, org.apache.xerces.xni.XMLAttributes attributes, org.apache.xerces.xni.Augmentations augs, int event) - Evaluates an XML resource with respect to an XPointer expressions
by checking if it's element and attributes parameters match the
criteria specified in the xpointer expression.

isFragmentResolved
public boolean isFragmentResolved()
throws org.apache.xerces.xni.XNIException
Returns true if the XPointer expression resolves to the current resource fragment
or Node which is part of the input resource being streamed else returns false.
- True if the xpointer expression matches a node/fragment in the resource
else returns false.
org.apache.xerces.xni.XNIException
- Thrown to signal an error
isXPointerResolved
public boolean isXPointerResolved()
throws org.apache.xerces.xni.XNIException
Returns true if the XPointer expression resolves any subresource of the
input resource.
- True if the xpointer expression matches a fragment in the resource
else returns false.
org.apache.xerces.xni.XNIException
- Thrown to signal an error
parseXPointer
public void parseXPointer(String xpointer)
throws org.apache.xerces.xni.XNIException
Parses an XPointer expression. It performs scheme specific processing
depending on the pointer parts and sets up a Vector of XPointerParts
in the order (left-to-right) they appear in the XPointer expression.
xpointer
- A String representing the xpointer expression.
org.apache.xerces.xni.XNIException
- Thrown if the xpointer string does not conform to
the XPointer Framework syntax or the syntax of the pointer part does
not conform to its definition for its scheme.
resolveXPointer
public boolean resolveXPointer(org.apache.xerces.xni.QName element,
org.apache.xerces.xni.XMLAttributes attributes,
org.apache.xerces.xni.Augmentations augs,
int event)
throws org.apache.xerces.xni.XNIException
Evaluates an XML resource with respect to an XPointer expressions
by checking if it's element and attributes parameters match the
criteria specified in the xpointer expression.
element
- - The name of the element.attributes
- - The element attributes.augs
- - Additional information that may include infoset augmentationsevent
- - An integer indicating
0 - The start of an element
1 - The end of an element
2 - An empty element call
- true if the element was resolved by the xpointer
org.apache.xerces.xni.XNIException
- Thrown to signal an error
