Matt,
I've _nearly_ got what I want but I'm not quite clear on how to change it to
get _exactly_ what I want.
First of all, I understand your suggestion much better now and have it
working 95%. This is my task:
<loadfile srcfile="${resume.src}\${resume.pkg}\ResumeConstants.java"
property="DESIRED_EMPLOYMENT_HISTORY_FORMAT">
<filterchain>
<tokenfilter>
<containsRegex flags="m" pattern="^[\s]*public static final
EmploymentHistoryFormats
DESIRED_EMPLOYMENT_HISTORY_FORMAT[\s]*=[\s]*([^;]+);[\s]*$" replace="\1"/>
</tokenfilter>
</filterchain>
</loadfile>
<echoproperties prefix="DESIRED"/>
<echo>DESIRED_EMPLOYMENT_HISTORY_FORMAT=${DESIRED_EMPLOYMENT_HISTORY_FORMAT}</echo>The echoproperties gives
me:DESIRED_EMPLOYMENT_HISTORY_FORMAT=EmploymentHistoryFormats.LIST_FORMAT\r\nThat would be perfect if it weren't for the '\r\n' at
the end. Even still,it may be good enough for my purposes. If you could tell me how to removethe carriage return and linefeed from
the end of the property, I'd love toknow. I'm afraid I'm very slow with REGEX patterns; I've tried severalchanges to the pattern
involving adding '\r\n' and '\s' but nothing works:rather than getting the result with the \r\n, I get no result at all so
I'mobviously messing up the match.But that's the small problem. The far bigger problem is that I'm havingtrouble displaying the
value. I am trying to do it in an AntMenu via thistask: <antmenu title="Verify Employment History Format"
stylesheet="${resume.xml.dir}\resume.style" image="${resume.xml.dir}\maximal.orange.129x30.jpg">
<label>The current value of the D
ESIRED_EMPLOYMENT_HISTORY_FORMAT constantin the ResumeConstants class is:${DESIRED_EMPLOYMENT_HISTORY_FORMAT}.</label> <label>When it does, press the Proceed button.</label>
<label>If you want to stop the build, press the Abort button.</label> <link label="Proceed" target="jar"/> <link label="Abort"
target="abort"/> </antmenu>Unfortunately, instead of displaying the _value_ of theDESIRED_EMPLOYMENT_HISTORY_FORMAT constant, it displays
this:${DESIRED_EMPLOYMENT_HISTORY_FORMAT}Now, I realize that you have nothing to do with AntMenu but perhaps you cansuggest another way to display the value of the property, using somedifferent task?
I could always display the value in one task and use theAntForm to give the option to proceed or abort.We're really getting close to having this work but I need just a little morehelp to get the rest
of the way.--Rhino----- Original Message -----From: "Matt Benson" <[EMAIL PROTECTED]>To: "Ant Users List" <[email protected]>Sent: Friday, Fe
