Hi volks,

I have a XML file with a lot of empty tag attributes. For instance:

<mytag id="">
  <ontent>aaa</content>
</mytag>
<mytag id="">
  <ontent>bbb</content>
</mytag>
<mytag id="">
  <ontent>ccc</content>
</mytag>

Now I want to replace id="" with e.g. id="2443" (id="[linenumber]")

I tried to do this with sed, but I did not get a successful result.

I hope someone here can help me :-)
