| org.springframework.xml.xpath.XPathOperations
All known Subclasses: org.springframework.xml.xpath.AbstractXPathTemplate,
| XPathOperations | | public interface XPathOperations (Code) | | Interface that specifies a basic set of XPath operations, implemented by various XPathTemplates. Contains numerous
evaluation methods,
The templates that implement this interface do not use precompiled XPath expressions. Consider using the
XPathExpressionFactory or the
XPathExpressionFactoryBean for optimal performance, but less flexibility.

| Method Summary | |
| List | evaluate(String expression, Source context, NodeMapper nodeMapper)
Evaluates the given expression, mapping each result
Node objects to a Java object via a
NodeMapper . | | void | evaluate(String expression, Source context, NodeCallbackHandler callbackHandler)
Evaluates the given expression, handling the result
Node objects on a per-node basis with a
NodeCallbackHandler . | | boolean | evaluateAsBoolean(String expression, Source context)
Evaluates the given expression as a boolean. | | double | evaluateAsDouble(String expression, Source context)
Evaluates the given expression as a double. | | Node | evaluateAsNode(String expression, Source context)
Evaluates the given expression as a
Node . | | List | evaluateAsNodeList(String expression, Source context)
Evaluates the given expression as a list of
Node objects. | | Object | evaluateAsObject(String expression, Source context, NodeMapper nodeMapper)
Evaluates the given expression, mapping a single
Node result to a Java object via a
NodeMapper . | | String | evaluateAsString(String expression, Source context)
Evaluates the given expression as a
String . |
| evaluate | | List evaluate(String expression, Source context, NodeMapper nodeMapper) throws XPathException(Code) | | Evaluates the given expression, mapping each result
Node objects to a Java object via a
NodeMapper .
Parameters:
expression - the XPath expression
