"meta": [{
	"context": "First",
	"fieldName": "test1",
	"scriptlang": "xpath",
	"script": "//a[1]"
},
{
	"context": "First",
	"fieldName": "test2",
	// as above but with:
	"flags": "o" // formerly "groupNum": -1
},
{
	"context": "First",
	"fieldName": "test2",
	// as above but with:
	"flags": "x"
}
] 

would generate the following different outputs:

"metadata": {
	"test1": [ "BBC" ],
	"test2": [{
		"href": "http://www.bbc.com",
		"content": "BBC"
	}],
	"hreftest3":"<a href=\"http://www.bbc.com",
		"content": "BBC"
	}]
}\">BBC</a>"
}

For reference, here is the complete set of flags for xpath (and regex, except for "O"):

• 'H': will HTML-decode resulting fields. (Eg "&" -> "&")
• 'o': if  the XPath expression points to an HTML (/XML) object, then this object is converted to JSON and stored as an object in the corresponding metadata field array. (Can also be done via the deprecated "groupNum":-1)
• 'x': if the XPath expression points to an HTML (/XML) object, then the XML of the object is displayed with no decoding (eg stripping of fields)
• 'D': described above 
• 'c': if set then fields with the same name are chained together (otherwise they will all append their results to the field within metadata)
