UNIX for Dummies Questions & Answers

Hi I have an XML file. Which has spaces between different records....

current file( Has many lines, like this... I want to delete all the spaces between > and <, if there are only spaces between them)

input file
<xyzr> <abc>1234</xyzr> <aaa> <bbb> ayz mnz</bbb> <sen>KEA EP</sen> <LAN>aa</LAN>


My output should look like (in a single line)
<xyzr><abc>1234</xyzr><aaa><bbb> ayz mnz</bbb><sen>KEA EP </sen> <LAN>aa</LAN>

Can some one help me out, how I can achieve this....

Try:
sed 's/> *</></g' < inputfile > outputfile

Iam on sun solaris....
sed 's/> *</></g' a1.t >a2.t is not working...
I tried the above command in different ways

sed 's/\> *\</\>\</g' a1.t >a2.t

sed 's/\> \</\>\</g' a1.t >a2.t

None of them are working.... a2.t is created with 0 bytes...

Well, here's an idea...try it the way I wrote it...

Code:

$ cat a1.t
<xyzr> <abc>1234</xyzr> <aaa> <bbb> ayz mnz</bbb> <sen>KEA EP</sen> <LAN>aa</LAN>

$ sed 's/> *</></g' < a1.t > a2.t
$ cat a2.t
<xyzr><abc>1234</xyzr><aaa><bbb> ayz mnz</bbb><sen>KEA EP</sen><LAN>aa</LAN>

$ uname -a
SunOS dev 5.6 Generic_105181-28 sun4d sparc SUNW,SPARCserver-1000
$

But also, your first modification looks like it should work....

Code:

$ rm a2.t
$ sed 's/> *</></g' a1.t >a2.t
$ cat a2.t
<xyzr><abc>1234</xyzr><aaa><bbb> ayz mnz</bbb><sen>KEA EP</sen><LAN>aa</LAN>

$

And it does for me.

There looks to be some tabs , null characters in between, I suppose...
They are not only spaces... Anyway to get rid of them

If it's just tab's it's easy. Except that you must actually type a tab character in the command and that won't show up here. I'll use TAB to indicate a tab character.

Code:

 sed 's/>[ TAB]*</></g' < a1.t > a2.t

How do I get a tab character?
