I have a lot of XML configuration files where I need to remove the following....
<filteredResources>
<filter>
<id>1396938000000</id>
<name></name>
<type>10</type>
<matcher>
<id>org.eclipse.ui.ide.multiFilter</id>
<arguments>1.0-projectRelativePath-matches-true-false-target</arguments>
</matcher>
</filter>
</filteredResources>

As per the help text of the find dialog
http://download.oracle.com/javase/6/docs/api/java/util/regex/Pattern.html
is the implementation engine of Eclipse find.

With Regular expression checked, all of the following find "Containing text:" string have not worked.
<filteredResources>.+<\/filteredResources>(?m).
(?m).<filteredResources>.+<\/filteredResources>

My guess is that since the XML stanza covers more than one line I need to turn on MULTILINE mode.

http://docs.oracle.com/javase/6/docs/api/java/util/regex/Pattern.html#MULTILINE

I found this little explanation, and came up with the following "Containing text", but it does not work either.

(?m)<filteredResources>.++$(\r\n?|\n)^.*+$(\r\n?|\n)^<\/filteredResources>

But it does not seem to be working. What is the proper way to use the
(?m).
token in the find string?

That ought to work, but doesn't it seem to work. I'm not sure why. This
however seems to work and handles both Windows and Linux line feeds.

<filteredResources>(.|[\n\r])+</filteredResources>
