Write a XML file by using Perl
$AutoRunKeywordsComments_Log = "qweak_daq_conf.xml";
my @automode_xml_tags = qw (QWEAKDAQ STATUS STARTKEYWORDS ENDKEYWORDS COMMENTS);
use XML::Writer;
my $output;
open($output, '>', $AutoRunKeywordsComments_Log) or die "Unable to open output file: $!";
my $writer = new XML::Writer(OUTPUT => $output);
$writer->xmlDecl();
$writer->startTag($automode_xml_tags[0]);
$writer->characters("\n");
$writer->startTag($automode_xml_tags[1]);
$writer->characters("auto");
$writer->endTag($automode_xml_tags[1]);
$writer->characters("\n");
$writer->startTag($automode_xml_tags[2]);
$writer->characters("Automode 1");
$writer->endTag($automode_xml_tags[2]);
$writer->characters("\n");
$writer->startTag($automode_xml_tags[3]);
$writer->characters("Automode 2");
$writer->endTag($automode_xml_tags[3]);
$writer->characters("\n");
$writer->startTag($automode_xml_tags[4]);
$writer->characters("This is the automode run log");
$writer->endTag($automode_xml_tags[4]);
$writer->characters("\n");
$writer->endTag($automode_xml_tags[0]);
$writer->end();
close $output;
So the output is
auto Automode 1 Automode 2 This is the automode run log
Read a XML file by using Perl
use XML::Simple;
my $ref = XMLin($AutoRunKeywordsComments_Log);
$AutoHClog_Status = $ref->{"$automode_xml_tags[1]"};
$AutoHClog_StartKeywords = $ref->{"$automode_xml_tags[2]"};
$AutoHClog_EndKeywords = $ref->{"$automode_xml_tags[3]"};
$AutoHClog_Comments = $ref->{"$automode_xml_tags[4]"};
Read a XML file by using Bash
rdom () { local IFS=\> ; read -d \< E C ;}
automode_xml=qweak_daq_conf.xml
while rdom; do
if [[ $E = STATUS ]]; then
automode_status=$C
elif [[ $E = STARTKEYWORDS ]]; then
automode_start_keywords=$C
elif [[ $E = ENDKEYWORDS ]]; then
automode_end_keywords=$C
elif [[ $E = COMMENTS ]]; then
automode_comments=$C
fi
done < $automode_xml
echo "---- Automode DAQ Status Settings"
echo "Auto Qweak DAQ status : $automode_status"
echo "Start Keywords : $automode_start_keywords"
echo "End Keywords : $automode_end_keywords"
echo "Comments : $automode_comments"
The rdom function is from a refererence
Read a XML file by using Tcl
Need the tDOM package.
load /lib/tdom0.8.3/libtdom0.8.3.so
proc read_autolog_xml {} {
global automode_status
global automode_start_keywords
global automode_end_keywords
global automode_comments
set autolog_xml qweak_daq_conf.xml
set xmlfile [open $autolog_xml]
set XML [read $xmlfile]
close $xmlfile
set doc [dom parse $XML]
set root [$doc documentElement]
set automode_status_node [$root selectNodes /QWEAKDAQ/STATUS/text()]
set automode_start_keywords_node [$root selectNodes /QWEAKDAQ/STARTKEYWORDS/text()]
set automode_end_keywords_node [$root selectNodes /QWEAKDAQ/ENDKEYWORDS/text()]
set automode_comments_node [$root selectNodes /QWEAKDAQ/COMMENTS/text()]
set automode_status [$automode_status_node data]
set automode_start_keywords [$automode_start_keywords_node data]
set automode_end_keywords [$automode_end_keywords_node data]
set automode_comments [$automode_comments_node data]
puts "Status : $automode_status"
puts "Start Keywords : $automode_start_keywords"
puts "End Keywords : $automode_end_keywords"
puts " Comments : $automode_comments"
}

Linus says: "C++ is a horrible language"
C++ is a horrible language. It's made more horrible by the fact that a
lot of substandard programmers use it, to the point where it's much
much easier to generate total and utter crap with it. Quite frankly,
even if the choice of C were to do nothing but keep the C++ programmers out, that in itself would be a huge reason to use C.
Linus
I am so glad, someone has the same feeling which I have now.
