Eclipse cannot create an XML file and the copied XML file does not appear with input prompts

This situation may be due to the lack of plugins associated with XML files in Eclipse.

Workaround: Open Eclipse,help-Install New software. Select the appropriate download source in the work with column, there will usually be a few URLs provided, of course, you can also point to the right of the add key, input Http://download.eclipse.org/webtools/repository/indigo, Name is a random name there. (Download source More than this, you can search again).

Because I need to solve the problem of XML plug-in, so in the space bar under work with the input XML can appear the corresponding plug-in, as long as the download on demand.
