Class AttributeTransformer
- All Implemented Interfaces:
SourceTransformer
${attribute(override):newAttribute}=prefix${attribute:oldAttribute}${option:suffix}
This would add the attribute newAttribute to the current sourceElement, and its content would be (in java notation) "prefix" + (currentElement.getAttribute("oldAttribute") == null ? "" : currentElement.getAttribute("oldAttribute")) + options.getOption("suffix")
On the left hand side, one can use attribute(override) (which replaces the attribute if its already there) and attribute(noOverride) which preserves the attribute if its already there. On the right hand side, you can use either plain text, ${attribute:attributeName} and ${option:optionName} in any combination. Escape character is the backslash. Lines starting with # and empty lines are disregarded.
