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

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.

- QName
The desired return type.
Returns
The Object that is the result of evaluating the expression and converting the result to
returnType.
