This is continuation to my previous email with
sugject line "Python regular expression". My text
file although, looks like .ini file, but it is not. It
is a chip definition file from Gene chip. it is a
huge file with over 340,000 lines.
I have particular set of question in general not
related to that file:
Characterstics of this text:
1. This text is divided into blocks and every block
start with 'Name'. The number of lines after this
identifier is random.
In this particular case how a particular logic I can
think of to extract some of these blocks is:
1.write a reg.exp to identify the Name identifier one
2. based on the this, ask the program to select all
lines after that until it hits either a new line OR
another name identifier:
How can I tell my program these 2 conditions:
1. mark the identifier i need and select all the lines
after that identifier until it hits a new line or
another name identifier.
please englihten me with your suggestions.
