Is it possible to use an xpath string on xml within a script activity?

[m083743]

I'd like to be able to use xpath on an xml rather than E4X, I know E4X works but I'd like to be able to use string expressions.
e.g.

var xml = new XML(
  <root>
    <item count="4"/>
  </root>
);

given the code above I'd like to be able to do something like xml.getValue("//@count").

I see that there is a method in the docs that should do what I want however i haven't been able to use it successfully.

If anyone could please help I would be extremely grateful.

Hi @m083743 ,

Use root.item.@count 

Thanks.

Hi Jyoti,

I'm well aware E4X syntax works but it won't allow me to use a string expression without using eval. I'm looking for something that allows me to use string expressions.

Thanks.

Hi,

Doc link isn't accurate here- XML objects in workflows don't have getValue().

Here are e4x equivalents for xpaths though, from https://svn.wso2.org/repos/wso2/tags/carbon/0.1alpha/mashup/java/xdocs/e4xquickstart.html:

XPathMeaningE4X Equivalent

element/*	Select all children of element	element.*
element/@*	Select all attributes of element	element.@*
element//descendent	Select all descendents (children, grandchildren, etc.) of element	element..descendent
.. or parent::element	Select the parent of element	element.parent()
xmlns:foo="..." element/foo:bar	Select the foo:bar child of element where foo is the prefix of a declared namespace	var foo = new Namespace(...); element.foo::bar
name(element)	Return the full name (including prefix if any) of element	element.name()
local-name(element)	Return the local name of element	element.localName()
namespace-uri(element)	Return the namespace uri (if any) of element	element.namespace()
element/namespace::*	Return the collection of namespaces as an Array of Namespace objects (E4X) or a nodeset of Namespaces nodes (XPath)	element.inScopeNamespaces()
element/processing-instructions(name)	Return the processing instruction children of element with the specified name (if omitted, all are returned).	element.processingInstructions(name)
string(element)	Return the concatenated text nodes of this element and all its descendants	stringValue(element); stringValue.visible = false; function stringValue(node) { var value = ""; if (node.hasSimpleContent()) { value = node.toString(); } else { for each (var c in node.children()) { value += stringValue(c); } } return value; }

xml.getValue("//@count") -> xml..@count 

Thanks,
