Dear Group:
(Version 6, Mac Os X)
This is the first time that I manipulate strings in Mathematica and I'm
getting constantly into trouble with the commands I'm familiar with, since
lists become strings, strings become lists and whatever.
I've got a long text that I need to classify in rows and columns.
Let's say that for each row I've got 3 columns. There are some collection of
words that identify rows and the different columns. The text looks somewhat
like this:
"Row 1 Identifier
text of column 1
Column 2 identifier
text of column 2
Column 3 identifier
text of column 3
Row 2 identifier
etc.
"
What I'd like as output is this:
{Row1Identifier, text of column1, text of column 2, text of column3, Row 2
Identifier, ....}
(or, finally: { {Row1Identifier, text of column1, text of column 2, text of
column3}, {Row 2 Identifier, ....}} )
There are many possible texts that identify Rows and Columns...I already
wrote a function with StringPosition
that tells me where the Rows and Columns begin...for example:
position = {2,4,5,7,8,15,26,204}
How can I use these positions to split the long string like I want to?
Thanks for your time!
cd
P.D.: I tried to use StringSplit first (without using the positions), but to
determine the positions I'm not only using patterns, so I didn't know how to
use that function for that.
