I have a data text file. One parts of this file looks like;
<Almanacs>
<svAlmanac>
<SVID>01</SVID>
<almanac>
<aSqRoot>0.0253906</aSqRoot>
<ecc>7.62939e-05</ecc>
<deltai>0.00683594</deltai>
<omega0>0.882233</omega0>
<omegaDot>-1.86265e-09</omegaDot>
<w>0.155792</w>
<m0>0.036377</m0>
<af0>-7.62939e-06</af0>
<af1>-1.09139e-11</af1>
<iod>1</iod>
<t0a>461400</t0a>
<wna>2</wna>
I need to extract each numeric values between > and < orderly. These numeric values' fractional parts are not constant within the data file.

See the help on "Importing XML Documents". You can probably use xmlread().

Yes, the file looks like xml, which shouldn't be parsed as if it was a text file without a great deal of care.
In particular, the order in which the tags appear is not guaranteed at all with xml, so just reading the numerical values without checking which tag they belong to would be extremely foolish.
As Image Analyst says, use xmlread and/or the file exchange xml2struct.
