How can I get autocompletion or intellisense or content assist options for XML attribute "values" using a preexsting sample XML(and nothing else) in some text editor?
For example If have
<samplexml attr="a">
</samplexml>
<samplexml attr="b">
</samplexml>
<samplexml attr="c">
</samplexml>
Then when I type <samplexml attr=
I should be shown the options a,b and c
I would like the above in Eclipse, but if not Eclipse is there some other open source tool which can give me this?
