The htmltablecellexists( function returns true if an HTML table contains the specified cell, false if it doesn’t.

---

Parameters

This function has three parameters:

table – text of the HTML table. If this parameter contains the body of an HTML table, the table must contain <tr> and <td> tags (however, the actual <table> and </table> tags themselves are not required).

row – row number within HTML table. Rows are numbered starting from 1.

column – column number within HTML table. Columns are numbered starting from 1.

---

Description

This function checks to see whether a cell in an HTML table exists or not. The result will be true if the cell exists, or false if it doesn’t. Suppose you set up a variable with an HTML table, like this:

local htable
htable = 
    "<tr><td><font size=-1>Alaska</font></td><td>AK</td></tr>
    <tr><td><font size=-1>Arizona</font></td><td>AR</td></tr>
    <tr><td><font size=-1>Wyoming</font></td><td>WY</td></tr>"

Once this variable is set up, you can check to see if different cells exist or not.

htmltablecellexists(htable,2,1) ☞ -1 (true)
htmltablecellexists(htable,3,2) ☞ -1 (true)
htmltablecellexists(htable,1,6) ☞ 0 (false)
htmltablecellexists(htable,6,1) ☞ 0 (false)

Note: This function is equivalent to:

tagdata(tagdata(thetable,"<tr","</tr>",row),"<td","</td>",col)<>""
