Thanks for spotting this bug. I will get it fixed. > What about doing it with a regexp though? > Is there any way to use a general regexp substitution > as a filter? I couldn't see how off hand. Yes, you definitely can do regexp substitution. The <containsregexp> filter currently gets lines that contain a regexp; it should not be too difficult to do <replaceregexp>, once you take a look at how <containsregexp> is done. > It needs to > be whole file substitute, not line by line. > There are two methods in BaseFilterReader: readLine and readFully: readLine will return the next line, while readFully will read the entire stream and return it as a string. You would use the readFully method and do regexp substitution on the returned string... For an example of how readFully is used, take a look at the <expandproperties> filter. > Duncan Harris Cheers, Magesh ************************************************* * Politician: One who shakes your hand before * * elections and your confidence after. * ************************************************* -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
