sed to replace a line with 2 or more different lines in same file
i have something like this...
Code:
cat filename.txt
<complexTypename="abc">
bklah vlah
blah 
blha blha blah
blha
 
</complexType >
<complexTypename="def">
bklah vlah
blah 
blha blha blah
blha
 
</complexType >
.
.
.and so on.. its a very large file

no i need to replace end of complex type that is
Code:
</complexType >

with
below three lines
Code:
 
<attribute name="123" type="string"></attribute>

Code:
<attribute name="456" type="string"></attribute>
</complexType >

or you could say put the two attributes lines just above </complexType >

this could be easily done in notepad++ but i want to do it in shell... and this attributes can be lenghty and cover different lines too..
like
Code:
 
<attribute name="456" type="string">
blah blha blha
blha blha
</attribute>


any help is deeply appreciated :-)

awk
Hi,

Try this one,

Code:
awk '/<\/complexType >/{print "<attribute name=\"123\" type=\"string\"></attribute>\n<attribute name=\"456\" type=\"string\"></attribute>";}1' file

Change the print statement based on your requirement.

Cheers,

Code:
awk 'BEGIN{i=1;while(getline line <"attribute.txt"){a[i]=line;i++;}}/<\/complexType >/{for(j=1;j<=length(a);j++){print a[j];}}1' file
