It would be highly appreciable if any one helps me in this. I am trying to get it done through Java but I love unix and believe it can be done within minutes with couple of lines.

The input log file is a text file contains multiple entries seperated by a blank line.
Each seperated entry corresponds to upgrade process information of one file.

!ENTRY text.....<INFO> or <OKAY> <RESOURCE: /test/src/com/test1/*/test.java> 2009-06-18 13:01:01.181
!MESSAGE Requesting upgrade report for file: test.java

!ENTRY text.....<INFO> or <OKAY> <RESOURCE: /test/src/com/test1/*/test1.java> 2009-06-18 13:01:01.181
!MESSAGE information in test1.java will be upgraded.
!SUBENTRY 1 com.bea.workshop.upgrade81 <INFO> <RESOURCE: full path /file name> 2009-06-18 13:02:25.681
!MESSAGE Will add import of org.apache.beehive.netui.pageflow.annotations.Jpf for JPF annotation support.

Each Entry starts with "!ENTRY" as shown above and will be followed by text "com.bea.workshop.upgrade81 " and then it will be followed by
two types of tags: <OKAY> and <INFO>
And then it will be followed by tag <RESOURCE:which contains the full path of the file and then followed by time stamp as shown above.

If it is <OKAY>, then second line will be as below
!MESSAGE Requesting upgrade report for file: filename ( Which is not of much importance for my output)

Ex:
!ENTRY text.....<INFO> or <OKAY> <RESOURCE: /test/src/com/test1/*/test.java> 2009-06-18 13:01:01.181
!MESSAGE Requesting upgrade report for file: file name

If it is <INFO> then also second line will be like
!MESSAGE Requesting upgrade report for file: filename
But it will certainly be followed by another set of multiple line pairs starting with tags !SUBENTRY,!MESSAGE like below

!SUBENTRY 1 com.bea.workshop.upgrade81 <INFO> <RESOURCE: path/filename> 2009-06-18 13:02:25.681
!MESSAGE Will add import of org.apache.beehive.netui.pageflow.annotations.Jpf for JPF annotation support.


My requirement is like below:

Requirement 1

1) For all entries containing <OKAY> tag, I need to extract the file names which will be after <RESOURCE:.....and before time stamp
Please note the entries are seperated by a blank line

Requirement 2

2) For all the lines with <INFO> tag, I would like to have a text file with entries like this

Full path and the file name and then in the next line
All the text after !MESAAGE right below the line containg the tag of corresponding "!SUBENTRY 1" tags
