nyms for words, and variables for numbers.
The items are separated by one or more "whitespace" characters
(e.g. space or TAB).  Thus, if a file contained the line
<p>
<TABLE SUMMARY="Example" BORDER="0" BGCOLOR="#efefef" WIDTH="100%">
<TR>
<TD>
<PRE>
<font color="#82140F">
Temperature 10.3
</font></PRE>
</TD>
</TR>
</TABLE>
<p>

then the line
<p>
<TABLE SUMMARY="Example" BORDER="0" BGCOLOR="#efefef" WIDTH="100%">
<TR>
<TD>
<PRE>
<font color="#82140F">        
read \var_name .var_value.
</font></PRE>
</TD>
