There is no difference in the installer for Xeams Community and Enterprise Edition. It will run as if you have purchased the Enterprise Edition for the first 30 days. It will then get converted to Community Edition unless a license is purchased.
Rafael,
It does use Perl-style regex. I recommend you download the RegexBuilder from https://web.synametrics.com/ToolsRegexBuilder.htm and try your samples in there. Check https://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html for reference. Xeams uses Regex that comes with Java.
