getTextValue

public static java.lang.String getTextValue(SessionFormFlow formValues,
                                            javax.servlet.http.HttpSession session,
                                            java.lang.String stylesheet)

Processes a stylesheet using the xml from the client's session as xml input.

Parameters:

formValues - The state of the formflow, which is used for retrieving the flowvalues, session etc.

session - The http session for retrieving the relevant session xml values.

stylesheet - The xsl stylesheet or simple parameter that should be processed.

Returns:

The value of the argument if the stylesheet argument doesn't contain xsl. Otherwise, an xml document is constructed which contains the session values in the session keys starting with "GX_". The userinfo and shopcart xml are added to this xml document aswell. The root element of the document is <handler>, so the path the xml stored in the GX_test session, will be /handler/test.

getTextValue

public static java.lang.String getTextValue(SessionFormFlow formValues,
                                            javax.servlet.http.HttpServletRequest req,

Returns:

The value of the argument if the stylesheet argument doesn't contain xsl. Otherwise, an xml document is constructed which contains the context values in the keys starting with "GX_". The userinfo and shopcart xml are added to this xml document aswell. The root element of the document is <handler>, so the path the xml stored in the GX_test session, will be /handler/test.
