I have an xml data file. I am trying to find a way to code inside a html
page to extract one row of data from the xml file and display it inside one
of the cells of a table. To select a particular row of data, each webpage
will have its own built-in value to point to that row.

Example:

Each row in the xml file has four columns of data, as follows:
variety_number, value_1, value_2, value_3

In each of html files, an unique variety_number is to be "hard-wired" and is
used to extract the three values from the row whose variety_number matches
the html file's variety_number. These three values are to be displayed
inside one cell in the output table (in html).

My website runs on an Unix platform.

Any help will be greatly appreciated. Thanks.
