Shell Programming and Scripting

Hi All,

My thanks in advance for you guys reading this and for any posts.

I'm having 100 XML files, I need script which replace a specific string.
It must be incrementing in 100 xml files..

Sample XML files:
<hwIPHostName type="attrib">DEMO1</hwIPHostName>

I need Demo1 to be incremented as DEMO2 in the next search likewise till DEMO100 of XML files. I've tried with Sed command but not working..

Can anyone help me out..

Code:

perl -pe 's|(<hwIPHostName type="attrib">)(Demo\d+?)(</hwIPHostName>)|$1.uc($2).$3|eg' *.xml

Use -i switch perl -i -pe ...... for in-file editing.

Hi balajesuri

Thanks for your reply.

But still it is not getting changed in the XML files. It shows me DEMO in all the files.

All files contain DEMO within that Tag. I need them to be incremented one by one in all the 100 files.

Not sure I quite understand your question. The way I saw it was you wanted to convert lowercase "Demo" to uppercase.

Ok, you have 100 xml files. First file has a tag containing DEMO1 which you want it to be converted to DEMO2.

Likewise, you want to increment the number besides DEMO by 1, in each of the xml files.

Is this what you're looking for?

Code:

[root@host dir]# cat 1.xml
<hwIPHostName type="attrib">DEMO1</hwIPHostName>
[root@host dir]# cat 2.xml
<hwIPHostName type="attrib">DEMO2</hwIPHostName>
[root@host dir]# cat 3.xml
<hwIPHostName type="attrib">DEMO3</hwIPHostName>
[root@host dir]# perl -pe 's|(<hwIPHostName type="attrib">DEMO)(\d+?)(</hwIPHostName>)|$1.($2+1).$3|eg' *.xml
<hwIPHostName type="attrib">DEMO2</hwIPHostName>
<hwIPHostName type="attrib">DEMO3</hwIPHostName>
<hwIPHostName type="attrib">DEMO4</hwIPHostName>
[root@host dir]#

You got it, It works it changes the value.

But for one change my files just contains the below in all the 100 files..

<hwIPHostName type="attrib">DEMO</hwIPHostName>

So i need that to be changed has the below order in all the other 100 files.

<hwIPHostName type="attrib">DEMO</hwIPHostName>
<hwIPHostName type="attrib">DEMO1</hwIPHostName>
<hwIPHostName type="attrib">DEMO2</hwIPHostName>
<hwIPHostName type="attrib">DEMO3</hwIPHostName>
..........................................................................
<hwIPHostName type="attrib">DEMO100</hwIPHostName>

I think you can do that..
