Subject RE: XMLProperty and CDATA

Hi,

By replacing org.apache.tools.ant.taskdefs.XmlProperty task method:

public Object processNode (Node node, String prefix, Object container)

By version below where is cdata section handled:

    /**
     * Process the given node, adding any required attributes from
     * this child node alone -- but <em>not</em> processing any
     * children.
     *
     * @param node the XML Node to parse
     * @param prefix A string to prepend to any properties that get
     * added by this node.
     * @param container Optionally, an object that a parent node
     * generated that this node might belong to.  For example, this
     * node could be within a node that generated a Path.
     * @return the Object created by this node.  Generally, this is
     * either a String if this node resulted in setting an attribute,
     * or a Path.
     */

        // properties for each.

path
        // which will be passed to the children of this node.
