Parameters:

selectorExpression - The selector expression.

Returns:

The set of selector steps.

Throws:

org.jaxen.saxpath.SAXPathException - Error parsing expression.

buildSteps

public static SelectorStep[] buildSteps(String selectorExpression,
                                        Properties namespaces)
                                 throws org.jaxen.saxpath.SAXPathException

Create a print friendly representation of the set of selector steps.

Parameters:

steps - The selector steps.

Returns:

A print friendly representation of the set of selector steps.
