# In sublime text must turn on regex and case sensativity.
#Grabs all attributes that start with sketch until last second qoute.
    \ssketch.[^"]*(["'])(?:(?=(\\?))\2.)*?\1

#Grabs all attributes that start with font-weight until last second qoute.
    \sfont-w.[^"]*(["'])(?:(?=(\\?))\2.)*?\1

#Grabs def,desc,title,svg tags and comments
    (?=(<def)|(<desc)|(<title)|(<\!)|(<svg)|(<\/svg)|(<\?)).+

#These don't work for <path + id=".*"
    id="[^"]*"
    (^[<path])id+.[^"]*(["'])(?:(?=(\\?))\2.)*?\1
    [^(?=(g)|(text)(rect))]\ id+.[^"]*(["'])(?:(?=(\\?))\2.)*?\1

#Process
#1. Remove unnedded html tags
    (?=(<def)|(<desc)|(<title)|(<\!)|(<svg)|(<\/svg)|(<\?)).+
#2. Remove empty lines
    ^\s*$
    or ^(\s*)[^<] this goes until the first < but won't include it
    (?:(\<\/\g\>)).\s* this grabs everthing from the last <\g> and all white space after
#3. Remove first and last line // crappy sketch wrapper which is useless
#4. Remove sketch attributes
    \ssketch.[^"]*(["'])(?:(?=(\\?))\2.)*?\1
#5. Remove font-weight
    \sfont-w.[^"]*(["'])(?:(?=(\\?))\2.)*?\1
#6. Make all id text lowercase
#7. Make all id underscores into mdash's
#8. Remove xlink:href="<!--base64-->" all images will its own path
    \sxlink.[^"]*(["'])(?:(?=(\\?))\2.)*?\1
