Creating file contents using contents of another file - Shell Programming and Scripting

ReV · #1 (**permalink**) 02-23-2006

Hi,

I am not sure how to start doing this so I hope to get some advice as to how to start.

I have 2 files. The source file contains data that I needed is in columns delimited by ";". For example, in this format:

Code:

"CONTINENT","COUNTRY","CITY","ID"
"asia","japan","tokyo","123"
"europe","germany","munich","456"
"africa","eygpt","cairo","789"

The output format is in xml format and the contents is something like:

Code:

<?xml version="1.0"?>
<!DOCTYPE ALR [
        <!ENTITY gt "&amp;gt;">
        <!ENTITY lt "&amp;lt;">
        <!ENTITY quot "&amp;quot;">
]>
<datafile>
        <info ID="#id should be here#">
                <info1>#continent name should be here'</info1>
                <info2> </info2>
                <info3>#country name should be here#</info3>
                <info4>#city name should be here#</info4>
                <info5>some fixed data</info5>
                <info6> </info6>
                <info7> </info7>
                <info8>some fixed data</info8>
                <info9>some fixed data</info9>
                <info10>some fixed data</info10>
                <info11>some fixed data</info11>
        </info>
        <action>
                <attributes>
                        <attributkey id="011" >N</attributkey>
                        <attributkey id="106" >N</attributkey>
                        <attributkey id="114" >N</attributkey>
                        <attributkey id="119" >N</attributkey>
                                        </attributes>
                <comment> </comment>
        </action>
</datafile>

There should be one output file created for each line in the source file.

Anyone can help? Thanks a lot!

See the solution in Want to show files on web page

You need to do something similiar.

Something like this

Code:

HEADER='<?xml version="1.0"?>
<!DOCTYPE ALR [
        <!ENTITY gt "&amp;gt;">
        <!ENTITY lt "&amp;lt;">
        <!ENTITY quot "&amp;quot;">
]>
<datafile>
        <info ID="'

function header {

echo "$HEADER" > output.xml
echo "$1" >> output.xml
echo "\">" >> output.xml

}

Parse the country specific details as

Code:

while read line
do
CONTINENT=$(echo "$line" | awk -F, '{ print $1 }')
COUNTRY=$(echo "$line" | awk -F, '{ print $2 }')
.
.

header $ID
done < input.file

where header is the method given above.

Use Ruby:

Code:

$out_count = 0

def process( str )

  str.strip!
  continent,country,city,id = str[1..-2].split(/","/)

  $out_count += 1
  File.open( "output_#{ $out_count }.xml", "w" ){|handle|

    handle.puts <<"HERE_DOC"
<?xml version="1.0"?>
<!DOCTYPE ALR [
        <!ENTITY gt "&amp;gt;">
        <!ENTITY lt "&amp;lt;">
        <!ENTITY quot "&amp;quot;">
]>
<datafile>
        <info ID="#{ id }">
                <info1>#{ continent }</info1>
                <info2> </info2>
                <info3>#{ country }</info3>
                <info4>#{ city }</info4>
                <info5>some fixed data</info5>
                <info6> </info6>
                <info7> </info7>
                <info8>some fixed data</info8>
                <info9>some fixed data</info9>
                <info10>some fixed data</info10>
                <info11>some fixed data</info11>
        </info>
        <action>
                <attributes>
                        <attributkey id="011" >N</attributkey>
                        <attributkey id="106" >N</attributkey>
                        <attributkey id="114" >N</attributkey>
                        <attributkey id="119" >N</attributkey>
                </attributes>
                <comment> </comment>
        </action>
</datafile>
HERE_DOC

  }
end


# Discard 1st line of file.
gets

# Read rest of file.
while gets
  process( $_ )
end

Save this code in file "make_xml.rb".
Run it with
ruby make_xml.rb my_input_file

The output files are named "output_1.xml", etc.

What is ruby command? When I tried to enter the command line you have written, it says "ruby:command not found"

It's readily available and open source. Could you download and install it?
