Hallo Gunter,
nachdem man mit
In[16]:= Clear[mx]
mx = Import[
"http://www.pvlighthouse.com.au/Resources/Photovoltaic%20materials/\
Refractive%20index/Refractive%20index.aspx", {"HTML", "Data"}];
In[23]:= Position[mx, "Wavelength"]
Out[23]= {{2, 2, 1, 2, 1, 1}, {2, 2, 1, 2, 1, 3}}
spoekengekiekt hat, wuergelt man
In[36]:= Remove[woyschHtml]
woyschHtml[s_String] := Block[{mx = Import[s, {"HTML", "Data"}], t},
t = mx[[Sequence @@ Drop[First[Position[mx, "Wavelength"]], -2]]];
TableForm[Drop[t, 2], TableHeadings -> {None, t[[1]]}]
]
mit
In[38]:=
woyschHtml["http://www.pvlighthouse.com.au/Resources/Photovoltaic%\
20materials/Refractive%20index/Refractive%20index.aspx"]
die Tabelle leidlich heraus.
Bei Verwendung von Grid[] koennen Sie jede einzelne Wabe behuebschen.
Gruss
Udo.
das
matrix=Flatten[Import["http://www.pvlighthouse.com.au/Resources/Photovoltaic%20materials/Refractive%20index/Refractive%20index.aspx",{"HTML","Data"}]/.{__String}:>Sequence[]//.{a___,s_String,b___}:>{a,b}//.{}:>Sequence[],4
];
MatrixForm@matrix
geht. Etwas heuristisch, aber na ja.
