    • execute

      public Document execute()
      This method does the actual DOM transformation we are interested in. If in Omnigraffle an object is marked with something like "VID-XYZ", where VID is a standard prefix for "Vector Identifier" and "XYZ" is the actual unique name describing the purpose of the object, then we ant to set this entire string as "id" in the dom. Similarly, the transformer detects objects marked with a "TID-" prefix, for "template ID". In the SVG generated by omnigraffle we have something like: (Tags removed so javadoc plugin is not confused) g id="Graphic_3" titleVID-SQUARE1/title rect x="230.8" y="193.9" width="105" height="105" fill="#40ff40"/ rect x="230.8" y="193.9" width="105" height="105" stroke="black" stroke-linecap="round" stroke-linejoin="round" stroke-width="1"/ text transform="translate(235.8 237.176)" fill="black" tspan font-family="Helvetica Neue" font-size="16" font-weight="400" fill="black" x="34.156" y="15" 361/tspan /text /g What we want is: g id="VID-SQUARE1" rect x="230.8" y="193.9" width="105" height="105" fill="#40ff40"/ rect x="230.8" y="193.9" width="105" height="105" stroke="black" stroke-linecap="round" stroke-linejoin="round" stroke-width="1"/ text transform="translate(235.8 237.176)" fill="black" tspan font-family="Helvetica Neue" font-size="16" font-weight="400" fill="black" x="34.156" y="15" 361/tspan /text /g p This method handles this transformation for an entire svg document.
