Grep并用特殊字符替换文本

Question

I have 10K+ XML where about half of them have the following line of code I'd like to replace:

<protocol_name_from_source><![CDATA[This section will be completed when reviewed by an Expert Review Panel.]]></protocol_name_from_source>

with this:

<protocol_name_from_source><![CDATA[Not applicable.]]></protocol_name_from_source>

I've been able to successfully grep for the affected files: grep -rl '<process\\_review><\\!\\[CDATA\\[<p>The Expert Review Panel has not reviewed this measure yet\\.<\\/p>\\]\\]><\\/process\\_review>' ./

but I can't seem to be able to replace the text with sed:

grep -rl '<process\\_review><\\!\\[CDATA\\[<p>The Expert Review Panel has not reviewed this measure yet\\.<\\/p>\\]\\]><\\/process\\_review>' ./ | xargs sed -i 's/<process\\_review><\\!\\[CDATA\\[<p>The Expert Review Panel has not reviewed this measure yet\\.<\\/p>\\]\\]><\\/process\\_review>/<process\\_review><\\!\\[CDATA\\[<p>Not applicable\\.<\\/p>\\]\\]><\\/process\\_review>/g'

Appreciate any help in advance.

edit: These XMLs are in a git repo. Is there any risk of corrupting the repo?

Hmm, according to my man page, sed -i option expect to be followed with one (eventually 0 length) extension. And the command option should be introduced with -e if it is not the only command parameter.

So here I would use:

grep -rl '<process\\_review><\\!\\[CDATA\\[<p>The Expert Review Panel has not reviewed this measure yet\\.<\\/p>\\]\\]><\\/process\\_review>' ./ | xargs sed -i '' -e 's/<process\\_review><\\!\\[CDATA\\[<p>The Expert Review Panel has not reviewed this measure yet\\.<\\/p>\\]\\]><\\/process\\_review>/<process\\_review><\\!\\[CDATA\\[<p>Not applicable\\.<\\/p>\\]\\]><\\/process\\_review>/g'

Beware, I have not reviewed the (long...) sed s/.../.../ command...
