I think I just looked at the second description
   I'd like to change "/DispForm.aspx?" to /EditForm.aspx?"
I am afraid with the full description of
   The link attribute {@ows_URL} has the value "http://mySiteUrl/
DispForm.aspx?ID=6"
my code sample does not work as you need it as there are several slashes 
in that string. So you are probably better off to use a named template 
that replaces a string and then construct the href attribute with 
xsl:attribute where you use xsl:call-template inside of the xsl:attribute.
