Hi, On an additional note, this is a major drawback that we have with several components in DevStudio. While trying to improve artfact.xml and pom.xml handling components, we recently came across [1], which is based on the concept of non extractive parsing[2]. Unfortunately this is licensed with GPL2 hence we cannot distribute it Apache license. I could not find a similar library with a compatible license. So either we can implement a framework with a similar algorithm or we need to go for complex regex based text replacing - if we cannot find any alternative.
