Add content of XML file to another one using bash script

Question

I have two XML file first one ~/tmp/test.xml second one /data/myuser/.mycontent/mytest.xml I want to add all of the content on the first XML file to line 35 in the second one. I tried the following but with no luck

sed -n '35,~/tmp/test.xml`' /data/myuser/.mycontent/mytest.xml

(cat /data/myuser/.mycontent/mytest.xml; echo) | sed '35r ~/tmp/test.xml'

ed -s ~/tmp/test.xml <<< $'35r /data/myuser/.mycontent/mytest.xml\nw'

Line 33 from second XML file line 34 is empty

#the following tags contain employee location

XML tag in the first XML file

<Location "/mylocation">
    first Address
    second Address

    Mylocation "XX/XX/XX/XX"
    Myphone "XXXXXXX"
</Location>

What did I do wrong, please advise .

Edit 1

first XML ~/tmp/test.xml file contain only

<Location "/mylocation">
    first Address
    second Address

    Mylocation "XX/XX/XX/XX"
    Myphone "XXXXXXX"
</Location>

second XML /data/myuser/.mycontent/mytest.xml contain:

NameVirtualHost *:XXXX
<VirtualHost  *:XXXX>

    ServerName AAAAAAAA

Edit 2 second file /data/myuser/.mycontent/mytest.xml should be like:

 NameVirtualHost *:XXXX
    <VirtualHost  *:XXXX>

        ServerName AAAAAAAA

    </employee>

    <Location "/">
            mylocation
            Deny from all

Note: ## this tag from first file and ## edit end to specify merge location location

Answer 1

With GNU sed:

If you want to insert file1.xml in file2.xml at line 35 with a leading newline:

sed -e '34{p;g;r file1.xml' -e '}' file2.xml

If you want to edit file2.xml "in place" add sed's option -i.

Answer 2

OK, so this isn't XML inserting into XML like I thought - if it was, the answer would be 'use a parser'. However it's not, you're just merging one text file into another.

So I would break out the perl as I so often do:

#!/usr/bin/env perl
use strict;
use warnings;

open ( my $insert, '<', '~/tmp/test.xml' ) or die $!;
open ( my $modify, '<', '/data/myuser/.mycontent/mytest.xml' ) or die $!; 
open ( my $output, '>', '/data/myuser/.mycontent/mytest.xml.new' ) or die $!; 

select $output; 
while ( <$modify> ) { 
   if ( $. == 32 ) { print <$insert>; }; 
   print; 
}

This should do the trick - if you're after a one liner, then it can be condensed down to:

perl -p -i.bak -e 'BEGIN { open ( $insert, "<", shift ) } if ( $. == 32 ) { print <$insert> }' ~/tmp/test.xml /data/myuser/.mycontent/mytest.xml

Note $. is perl for "current line number". You can apply a different sort of conditional if you prefer. Like whether a regex matches (which might be more appropriate, given config files tend to get lines inserted into them).

Answer 3

I think I understand the problem with you're attempting to do. It looks like you maybe want to insert your read file on an input cue. You say line 35, but if you do sed 35r\ file that will be appended to 35. It's hard to watch input for a cue before which you want to write output if you don't secure a lookahead. For example:

sed -e'$!N;/\n<Location "\/employee1">/r /tmp/file1' \
    -eP\;D </tmp/file2 | tail -n30

---

Now that scans input for the <Location /employee1> and inserts the content of file1 immediately before it once found.
