Re: read/write in the same xml file

2003-06-11 03:21:26
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.

what i need is to know how much characters i have write in the output file
each time, because i want to make a table of contents like this:
paragraph1  begining  end
---------     ------    ----
paragraph i  ------     ----

the begining and the end  position are exprimed in characters.

so for this reason i want to use an extern file named compte.xml
which i will use in my stylesheet every time for knowing the position.

Ah, well you could pass your external filename in as a parameter at
runtime, instead of hardcoding it.

As far as knowing how many characters precede a given position (say, the
start of a paragraph), are you speaking of characters irrespective of
markup, or characters including markup? That is, given

<text>
  <p>Here's paragraph one.</p>
  <p>Here's paragraph two.</p>
</text>

Do you want the first p to yield 0 (or perhaps 2 if you count the
whitespace after the <text> start tag) and the second, 21 (the length of
the first p)? Or do you want an absolute character offset including the
characters that appear in the start tags "<text>", "<p>" and so on?

If the first, it can be done in XSLT, although it's not necessarily the
best tool for the job. If you mean the second, XSLT is certainly *not* the
tool for the job since the XSLT source tree (created by parsing the file)
does not keep track of tags.

Please clarify.

Cheers,
Wendell
