I'm using GNU sed version 4.1.2

<div>
I am unable to test that here but I don't see the issue with the alternation.

Hello,<br />
<br />
Here is an example of my data:<br />
<br />
&lt;frame context=&quot;.*/batch&quot;&gt;<br />
&lt;/frame&gt;<br />
&lt;frame context=&quot;.*/continuous&quot;&gt;<br />
&lt;/frame&gt;<br />
<br />
==========================<wbr />======<br />
<br />
I am trying convert the above data to look like:<br />
&lt;frame&gt;<br />
&lt;/frame&gt;<br />
&lt;frame&gt;<br />
&lt;/frame&gt;<br />
<br />
==========================<wbr />======<br />
<br />
I currently have these two sed scripts that do the job, but I am trying to combine into one statement:<br />
<br />
&nbsp; &nbsp; &nbsp;sed -i &quot;/&lt;frame /,/&gt;/ s/ context=\&quot;\.\*\/batch\&quot;//g<wbr />&quot; $PRODUCTDIR/kb/framesPTP.x<wbr />ml<br />
&nbsp; &nbsp; &nbsp;sed -i &quot;/&lt;frame /,/&gt;/ s/ context=\&quot;\.\*\/continuous<wbr />\&quot;//g&quot; $PRODUCTDIR/kb/framesPTP.x<wbr />ml<br />
<br />
<br />
I tried:<br />
<br />
&nbsp; &nbsp; &nbsp;sed -i &quot;/&lt;frame /,/&gt;/ s/ context=\&quot;\.\*\/(batch|con<wbr />tinuous)\&quot;<wbr />//g&quot; $PRODUCTDIR/kb/framesPTP.x<wbr />ml<br />
<br />
But it does not work for me. &nbsp;When I use the pipe to get the either/or it doesn't do any substitution at all. &nbsp;Help please.<br />
<br />

Hello,

Here is an example of my data:

<frame context=".*/batch">
</frame>
<frame context=".*/continuous">
</frame>

================================

I am trying convert the above data to look like:
<frame>
</frame>
<frame>
</frame>

================================

I currently have these two sed scripts that do the job, but I am trying to combine into one statement:

     sed -i "/<frame /,/>/ s/ context=\"\.\*\/batch\"//g" $PRODUCTDIR/kb/framesPTP.xml
     sed -i "/<frame /,/>/ s/ context=\"\.\*\/continuous\"//g" $PRODUCTDIR/kb/framesPTP.xml


I tried:

     sed -i "/<frame /,/>/ s/ context=\"\.\*\/(batch|continuous)\"//g" $PRODUCTDIR/kb/framesPTP.xml

But it does not work for me.  When I use the pipe to get the either/or it doesn't do any substitution at all.  Help please.




Does SED support alternation regular expression?

The term 'shell' refers to a general class of text-based command interpreters most often associated with the UNIX and Linux operating systems. Popular shells include Bourne, Debian Almquist (dash), Korn (ksh), Bourne Again (bash) and the C shell family (csh). Some view the DOS 'cmd' prompt as a minimal shell of sorts. It is also possible to install Cygwin on Windows and emulate a full Unix environment with complete shell capabilities. Terminal emulators, such as xterm, GNOME Terminal and OS X Terminal, can be used to access shell.

Shell Scripting

A regular expression ("regex") is a sequence of characters that define a search pattern, mainly for use in pattern matching with strings, or string matching, i.e. "find and replace"-like operations. Regular expression processors are found in several search engines, search and replace dialogs of several word processors and text editors, and in the command lines of text processing utilities, such as sed and AWK. Many programming languages provide regular expression capabilities, some built-in, for example Perl, JavaScript, Ruby, AWK, and Tcl, and others via a standard library, for example .NET languages, Java, Python and C++ (since C++11). Most other languages offer regular expressions via a library.
