[lug] vi wildcards

Are you trying to delete all the tags that start with "<SPAN CLASS" and 
end with ">" ?  If so, it looks like you need the . metacharacter.  It 
represents the character generated by the "any" key.  :-)

The patterns you have below will match
<SPAN CLASS="""""""""""""""""""""">
or anything with only quotes and a > following the CLASS.  I believe if 
you use
:%s/<SPAN CLASS=".*">//g
that it will work.  Also, 1,$s works as well.  The % is the same as 1,$.
The * is a count qualifier and means match 0 or more of the preceeding 
character.  This is not to be confused with glob matching like you get 
in the shell.  A glob type pattern of  "* would match "abc or """"" , 
where as a regular expression pattern of "* would match """"" but *not* "abc
