Sed functionality

collern2 · 02-25-2006, 04:25 PM

I have a few xml files and I want to input say 5 parameters within each file. is it possible to do so with sed?

<parameter>A</parameter>

<parameter>B</parameter>

....
....

And so on.

These parameters are meant to go in just inside:
<?xml version="1.0" encoding="utf-8"?>
<config xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance">

of each file? Any ideas?

Just after:
<?xml version="1.0" encoding="utf-8"?>
<config xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance">

Awk or sed, it doesn't really matter. Newbie here

If you just want to extract your parameters with sed, try this:
$ sed -n 's/<par>$.*$<\/par>/\1/p' f1
In my experiment `f1' looks like
<par>A</par>
<par>B</par>

Note that this doesn't work if <par> and </par> on different lines.

Use "cat file | tr '\n \t' ' ' | sed ... " command to convert file to one big line.
