 public final class LineContainsRegExp extends BaseParamFilterReader implements ChainableReader Filter which includes only those lines that contain the user-specified regular expression matching strings. Example:<linecontainsregexp> <regexp pattern="foo*"> </linecontainsregexp> Or:<filterreader classname="org.apache.tools.ant.filters.LineContainsRegExp"> <param type="regexp" value="foo*"/> </filterreader>This will fetch all those lines that contain the patternfoo
