Replace 2 Character With One Using tr
Hi,

I have an XML file which is all on one line.

Code:
<?xml version="1.0" encoding="utf-8"?><FUNCTION><PRODUCTS><PRODUCT CODE="PROD1" ACTION="amend" VALIDATE="no"><SUPPLIER PRODUCT="SUPPPROD1" ACTION="amend" CODE="SUPPLIER"><STOCK_QUANTITY DATA="291"></STOCK_QUANTITY> <STOCK_DATE DATA="1277942400"></STOCK_DATE></SUPPLIER></PRODUCT></FUNCTION>

I am trying to replace the string >< with > \n < but can't seam to do this.

If I used
Code:
cat COMPGEAR.txt2010-07-01T083239.xml | tr "><" ">\n<"

It outputs the following
Code:
?xml version=1.0 encoding=utf-8?>
FUNCTION>
PRODUCTS>
PRODUCT CODE=PROD1 ACTION=amend VALIDATE=no>
SUPPLIER PRODUCT=SUPPPROD1 ACTION=amend CODE=SUPPLIER>
STOCK_QUANTITY DATA=291>
/STOCK_QUANTITY>
STOCK_DATE DATA=1277942400>
/STOCK_DATE>
/SUPPLIER>
/PRODUCT>
/FUNCTION>

But I need it to bring out the following
Code:
<?xml version="1.0" encoding="utf-8"?>
<FUNCTION>
<PRODUCTS>
<PRODUCT CODE="PROD1" ACTION="amend" VALIDATE="no">
<SUPPLIER PRODUCT="SUPPPROD1" ACTION="amend" CODE="SUPPLIER">
<STOCK_QUANTITY DATA="291">
</STOCK_QUANTITY>
<STOCK_DATE DATA="1277942400">
</STOCK_DATE>
</SUPPLIER>
</PRODUCT>
</FUNCTION>

Can anyone tell me how to do this?

You need sed, not tr in this case:

Code:
sed 's/></>\n</g' infile

Most sed implementations do not support escape sequences in the RHS,
with those implementations you'll need something like this:

Code:
sed 's/></>\
</g' infile

Thanks for the quick replies.

radoulov - I tired your method and didn't bring back any results. I'm not sure what I did wrong.

I tried
Code:
sed 's/></>\n</g' COMPGEAR.txt2010-07-01T083239.xml

and I tried
Code:
COMPGEAR.txt2010-07-01T083239.xml | sed 's/></>\n</g'

neither of them brought back any resuts

pseudocoder - your solution seemed to work perfectly thank you.
