|
||
contents of some display that is not actually intended for data transport
|
||
or inspection by programs. Around 1980 this term referred to tricks like
|
||
reading the display memory of a smart terminal through its auxiliary
|
||
port. Nowadays it often refers to parsing the HTML in generated web pages
|
||
with programs designed to mine out particular patterns of content. In
|
||
either guise screen-scraping is an ugly, ad-hoc, last-resort technique that
|
||
is very likely to break on even minor changes to the format of the data
|
||
being snooped.</p></dd><div class="navfooter"><hr/><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="screen-name.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="../S.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="screw.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">screen name </td><td width="20%" align="center"><a accesskey="h" href="../index.html">Home</a></td><td width="40%" align="right" valign="top"> screw</td></tr></table></div></body></html>
