For preventing Internet requests you can use option "ReadDTD"->False
though the result will be slightly different:

In[1]:=
xml1=ImportString[ExportString[Plot[x^4,{x,0,1}],"SVG"],"XML",
    "ReadDTD"->False];
xml2=ImportString[ExportString[Plot[x^4,{x,0,1}],"SVG"],"XML"];
xml1===xml2
Complement[xml2,xml1]
AppendTo[xml1,"Valid"->True]===xml2

Out[3]= False
Out[4]= XMLObject[Document][Valid->True]
Out[5]= True

Interestingly, there is another related option in the Documentation:
"AllowRemoteDTDAccess". But with this option ImportString fails:

ImportString[ExportString[Plot[x^4,{x,0,1}],"SVG"],"XML",
    "AllowRemoteDTDAccess"->False];
XML`Parser`XMLGetString::prserr: StyleBox[RuntimeException:Could not
open
DTD file'http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd'
atLine:1Character:99,MT]

Both these options absent in Mathematica 5.2.
