Hello,

I want to search two strings in a file and print the same in the new file using perl script.
Can anyone suggest me how to do this...
The file looks like below:

<UML:ModelElement.requirement>
<UML:Dependency name="Row_MainColumn_FW_0009">													<UML:ModelElement.taggedValue>
<UML:Requirement="Column_MainRow_FW_0010">

I want to search the string start with ROW_ or Column_

Any suggestion on this

2 
perl -ne 'print "$1\n" if /((?:ROW|COLUMN)_\w+)/' $filename
3

That works...
Thanks a lot

The output shall be like this:

<UML:Dependency name="Row_MainColumn_FW_0009">													
<UML:Requirement="Column_MainRow_FW_0010">
