Constructor Detail

JDOMXPath

public JDOMXPath(java.lang.String expr)
          throws JDOMException

Deprecated.

Creates a new XPath wrapper object, compiling the specified XPath expression.

Parameters:

expr - the XPath expression to wrap.

Throws:

JDOMException - if the XPath expression is invalid.

Method Detail

selectNodes

public java.util.List<?> selectNodes(java.lang.Object context)
                              throws JDOMException

Deprecated.

Evaluates the wrapped XPath expression and returns the list of selected items.

Specified by:

selectNodes in class XPath

Parameters:

context - the node to use as context for evaluating the XPath expression.

Returns:

the list of selected items, which may be of types: Element , Attribute, Text, CDATA, Comment , ProcessingInstruction, Boolean, Double, or String.

Throws:

JDOMException - if the evaluation of the XPath expression on the specified context failed.

selectSingleNode

public java.lang.Object selectSingleNode(java.lang.Object context)
                                  throws JDOMException

Deprecated.

Evaluates the wrapped XPath expression and returns the first entry in the list of selected nodes (or atomics).

Specified by:

selectSingleNode in class XPath

Parameters:

context - the node to use as context for evaluating the XPath expression.

Returns:

the first selected item, which may be of types: Element, Attribute, Text, CDATA, Comment, ProcessingInstruction, Boolean, Double, String, or null if no item was selected.

Throws:

JDOMException - if the evaluation of the XPath expression on the specified context failed.

valueOf

public java.lang.String valueOf(java.lang.Object context)
                         throws JDOMException

Deprecated.

Returns the string value of the first node selected by applying the wrapped XPath expression to the given context.

Specified by:

valueOf in class XPath

Parameters:

context - the element to use as context for evaluating the XPath expression.

Returns:

the string value of the first node selected by applying the wrapped XPath expression to the given context.

Throws:

JDOMException - if the XPath expression is invalid or its evaluation on the specified context failed.

numberValueOf

public java.lang.Number numberValueOf(java.lang.Object context)
                               throws JDOMException

Deprecated.

Returns the number value of the first item selected by applying the wrapped XPath expression to the given context.

Specified by:

numberValueOf in class XPath

Parameters:

context - the element to use as context for evaluating the XPath expression.

Returns:

the number value of the first item selected by applying the wrapped XPath expression to the given context, null if no node was selected or the special value Double.NaN (Not-a-Number) if the selected value can not be converted into a number value.

Throws:

JDOMException - if the XPath expression is invalid or its evaluation on the specified context failed.

setVariable

public void setVariable(java.lang.String name,
                        java.lang.Object value)
                 throws java.lang.IllegalArgumentException

Deprecated.

Defines an XPath variable and sets its value.

Specified by:

setVariable in class XPath

Parameters:

name - the variable name.

value - the variable value.

Throws:

java.lang.IllegalArgumentException - if name is not a valid XPath variable name or if the value type is not supported by the underlying implementation

addNamespace

public void addNamespace(Namespace namespace)

Deprecated.

Adds a namespace definition to the list of namespaces known of this XPath expression.

Deprecated.

Returns the wrapped XPath expression as a string.

Specified by:
