Syntax

Element	Rules	Description
type	Mandatory	mls
operator	Mandatory	required a document specifying properties for the directory listing
target	Optional	the target resource

The mls accessor walks the modules virtual filesystem to generate an xml document representation of the resource URI tree structure.

The resources that are matched are selected based upon a set a regular expression filter applied to the resource URI. The resource filter is provided as the operator.

The resulting document is hierarchical tree representation of the virtual filesystem tree. The structure of the returned document is as follows

<mls> ...
  <dir>accessor
    <res>schematronAccessor.idoc
      <uri>ffcpl:/org/ten60/netkernel/xml/accessor/schematronAccessor.idoc</uri>
      <module>urn:org:ten60:netkernel:ext:xml</module>
    </res>
  </dir> ...
</mls>

Operator Syntax

The mls accessor requires some properties to specify what to include in the listing. These are passed in by the operator in a <mls> property document.

<module-uri> If specified, this is the modules that will be the subject of the listing. Otherwise the module requesting use of the accessor will be the subject.
<filter> Filter. Regular Expression on the full path of the resource
<recursive> Will include resources in imported modules.
<uri> Include the full ffcpl: URI of the resource
<module> Include the URI of the module in which the resource is located
