org.apache.tools.ant.filters.LineContainsRegExp
- All Implemented Interfaces:
- Closeable,- AutoCloseable,- Readable,- ChainableReader,- Parameterizable
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 pattern foo-
