Writing the logcat into an xml file in android

Question

I am a little bit novice in android. I actually want to write the information that is shown in the logcat into an xml file that will be saved in the phone or in the computer. Here is the logcat shown for my application and I would like to actually save the Pressure and Size in to an xml file under the Pressure/Size tag. How can I do that?

You can't on modern android. As of 4.2, apps can't access the logfile anymore. YOu'll have to do this on the PC.

After MotionEvent occurs a text is shown in a TextView. How can I write that text into an xml file? – SaberTooth Apr 03 '13 at 20:55
Oh, you can do a variety of work arounds- write your own logging function that writes to a file on the SD card, for example. And then you could do it in XML more easily. You just can't see what's being written to logcat, by your app or any other. – Gabe Sechan Apr 03 '13 at 20:58

A Perl script to run on your local PC using perl :

Require the logcat output in input_file.log

#!/usr/bin/perl

use strict; use warnings;
use XML::Simple;

my $h = {};

print "<?xml version='1.0' encoding='UTF-8'?>\n";

while (<>) {
    chomp;
    my @F = split;
    push @{ $h->{item} }, {
        date => "$F[0] $F[1]",
        system => $F[2],
        $F[3] => $F[4]
    }
}

my $xs = new XML::Simple;
my $xml = $xs->XMLout($h, NoAttr => 1, RootName => "tree");
print $xml;

Usage

./script.pl < input_file.log

Output

<?xml version='1.0' encoding='UTF-8'?>
<tree>
  <item>
    <Pressure>0.23333335</Pressure>
    <date>04-04 02:38:45.057:</date>
    <system>I/System.out(14272):</system>
  </item>
  <item>
    <Size>0.227451</Size>
    <date>04-04 02:38:45.057:</date>
    <system>I/System.out(14272):</system>
  </item>
  <item>
    <Pressure>0.20000002</Pressure>
    <date>04-04 02:38:46.217:</date>
    <system>I/System.out(14272):</system>
