get INPUT value within TD
the htmlcode:
<tr><td>a</td><td>b</td><td><input type="text"></td></tr>
<tr><td>c</td><td>d</td><td><input type="text"/></td></tr>
<tr><td>e</td><td>f</td><td><input type="text"></td></tr>
problem:
i need only the value of td's in each trrow when there's a value filled in in the input field.
suppose in first and last tr there's a value for 'input' i have to get this result: a:b:inputvaluee:f:inputvalue
where ':' is divider between rowvalues and '' splitter between each row
