```
public XPathFilterParameterSpec(String xPath)
```
Creates an XPathFilterParameterSpec with the specified XPath expression.

Parameters:

xPath - the XPath expression to be evaluated

Throws:

NullPointerException - if xPath is null

XPathFilterParameterSpec
```
public XPathFilterParameterSpec(String xPath,
                                Map<String,String> namespaceMap)
```
Creates an XPathFilterParameterSpec with the specified XPath expression and namespace map. The map is copied to protect against subsequent modification.

Parameters:

xPath - the XPath expression to be evaluated

Throws:

NullPointerException - if xPath or namespaceMap are null

ClassCastException - if any of the map's keys or entries are not of type String
