Creating a larger .xml file from a template(sample file)

Shell Programming and Scripting
1

Dear All,

I have a template xml file like below.

....Some---Header.......
<SignalPreference>
        ...
        <SignalName>STRING</SignalName>
        ...
</SignalPreference>
......Some formatting text.......
<SignalPreference>
        .........
        <SignalName>STRING</SignalName>
</SignalPreference>
....Some footer text......

I want to create an actual .xml like below.
For 2 instances of my signals output shown below, preserving all header, footer and other formatting tags.

....Some---Header....... ## Must preserve all the header tags
<SignalPreference>
        ...   #Must preserve this part as it is
        <SignalName>STRING1</SignalName>
        ...  #Must preserve this part as it is
</SignalPreference>
<SignalPreference>
        ...  #Must preserve this part as it is
        <SignalName>STRING2</SignalName>
        ...  #Must preserve this part as it is
</SignalPreference>

......Some formatting text.......   ### must Preserve this as it is

<SignalPreference>
        .........  #Must preserve this part as it is
        <SignalName>STRING1</SignalName>
        ......... #Must preserve this part as it is
</SignalPreference>
<SignalPreference>
        ...  #Must preserve this part as it is
        <SignalName>STRING2</SignalName>
        ...  #Must preserve this part as it is
</SignalPreference>

....Some footer text......  ### Must preserve this as it is.

where STRING1,STRING2 etc are from one more text file signal.txt.
cat Signal.txt

STRING1
STRING2
........ so on
up to 10000 STRINGS

Currently I am manually replicating the <SignalPreference>.. </SignalPreference> tag portions and replacing <SignalName>STRING </SignalName> with my desired string based on line number using grep and sed commands. But this is becoming a very tedious task as I have many tags to replace with.

Thanks

Check out the below example, you should be able to modify it to do what you want:

$ cat t
STRING1
STRING2
STRING3
STRING4


## perl script
print "....Some---Header....... ## Must preserve all the header tags\n";
open ( STRINGS, "</temp/tmp/t") or die ("***Error- Couldn't open file: C:/temp/tmp/t, $!\n");
while ( <STRINGS> ) {
  chomp;
  print "<SignalPreference>\n";
  print "        ...   #Must preserve this part as it is\n";
  print "        <SignalName>$_</SignalName>\n";
  print "        ...  #Must preserve this part as it is\n";
  print "</SignalPreference>\n";
  print "\n";
  print "......Some formatting text.......   ### must Preserve this as it is\n";
}
close STRINGS;
print "....Some footer text......  ### Must preserve this as it is.\n";


$ test.pl
....Some---Header....... ## Must preserve all the header tags
<SignalPreference>
        ...   #Must preserve this part as it is
        <SignalName>STRING1</SignalName>
        ...  #Must preserve this part as it is
</SignalPreference>

......Some formatting text.......   ### must Preserve this as it is
<SignalPreference>
        ...   #Must preserve this part as it is
        <SignalName>STRING2</SignalName>
        ...  #Must preserve this part as it is
</SignalPreference>

......Some formatting text.......   ### must Preserve this as it is
<SignalPreference>
        ...   #Must preserve this part as it is
        <SignalName>STRING3</SignalName>
        ...  #Must preserve this part as it is
</SignalPreference>

......Some formatting text.......   ### must Preserve this as it is
<SignalPreference>
        ...   #Must preserve this part as it is
        <SignalName>STRING4</SignalName>
        ...  #Must preserve this part as it is
</SignalPreference>

......Some formatting text.......   ### must Preserve this as it is
....Some footer text......  ### Must preserve this as it is.

Hi Spacebar,

I am working on the perl script you mentioned.
Can you let me know on how to print some text containing

""

in it using perl command

print

. ??
Example: I have below text to be printed with print.

<?xml version="1.0" encoding="utf-8"?>

Except this looks like I can do rest of the things.

Regards
Sidda

You can do it like this:

print '<?xml version="1.0" encoding="utf-8"?>';
