## org.apache.tools.ant.taskdefs
Class XmlProperty

    java.lang.Object
      org.apache.tools.ant.ProjectComponent
          org.apache.tools.ant.Task
              org.apache.tools.ant.taskdefs.XmlProperty

public class XmlProperty
extends Task

Loads property values from a valid XML file, generating the property names from the file's element and attribute names. Example:

       <root-tag myattr="true">
         <inner-tag someattr="val">Text</inner-tag>
         <a2><a3><a4>false</a4></a3></a2>
       </root-tag>

this generates

      root-tag(myattr)=true
      root-tag.inner-tag=Text
      root-tag.inner-tag(someattr)=val
      root-tag.a2.a3.a4=false
