Good luck,

this is an example for what i want to do:

i supose this is my xml file:
<document>
<para>
<word>aaa</word>
<word>bbb</word>
<word>ccc</word>
<word>ddd</word>
<word>eee</word>
</para>
<para>
<word>kkk</word>
<word>fff</word>
<word>mmm</word>
<word>ppp</word>
</para>
</document>

my output file should have this structure:

table of contents:
paragraph1  12    32
paragraph2  44  59

paragraph1
aaa
bbb
ccc
ddd
eee
paragraph2
kkk
fff
mmm
ppp

so the first paragraph begin in character 12 and finish in character 32

in the output file.
