Regex to remove comments in XML file in Eclipse java

Can anyone tell me how to write a regular expression to match the comments in XML file, for example,

<!-- Global JNDI resources
   Documentation at /docs/jndi-resources-howto.html
-->

I'm using Eclipse (java) and want开发者_开发问答 to remove those comments from XML file.

xmlFileContent.replaceAll( "(?s)<!--.*?-->", "" );

xmlFileContent.replaceAll("<!--[\s\S]*?-->", "");

[\s\S] works like '.', but will consume line endings as well.

xmlFileContent.replaceAll("<!--.*?-->", "");
