abstract member Evaluate : Java.Lang.Object -> string

Parameters

item
Object

The starting context (node or node list, for example).

Returns

The String that is the result of evaluating the expression and converting the result to a String.

Attributes

Exceptions

If the expression cannot be evaluated.

Remarks

Evaluate the compiled XPath expression in the specified context and return the result as a String.

This method calls #evaluate(Object item, QName returnType) with a returnType of XPathConstants#STRING.

See Evaluation of XPath Expressions for context item evaluation, variable, function and QName resolution and return type conversion.

If a null value is provided for item, an empty document will be used for the context.

abstract member Evaluate : Org.Xml.Sax.InputSource -> string

Parameters

source
InputSource

The InputSource of the document to evaluate over.

Returns

The String that is the result of evaluating the expression and converting the result to a String.

Attributes

Exceptions

If the expression cannot be evaluated.

If source is null.

Remarks

Evaluate the compiled XPath expression in the context of the specified InputSource and return the result as a String.

This method calls #evaluate(InputSource source, QName returnType) with a returnType of XPathConstants#STRING.

See Evaluation of XPath Expressions for context item evaluation, variable, function and QName resolution and return type conversion.

If source is null, then a NullPointerException is thrown.
