XPath - Discard Certain Table Rows

I'm using PHP DOM and DOMXPath class. This is what I have in essence:

<table>
    <tr>
        <td><div> More data </div></td>
    </tr>
    <tr>
        <td><div> More data </div></td>
    </tr>
    <tr>
        <td><div> More data </div></td>
    </tr>
    <tr>
        <td><div> More data </div></td>
    </tr>
    // I want all of these removed
    <tr>
        <td class="className"></td> // Nothing between <td> tags here
    </tr>
    // Repeat N times
    .
    .
    .
    .
</table>

This is a pattern of rows and repeats plenty of times.

What I want is an XPath expression which will get me all the rows but discard every row like the last one in this example.

To be clear: not the last row only but discard every row which meets some criteria and return others.

Solution

  • You can use normalize-space() to filter out empty nodes, for example :

    /table/tr[normalize-space(.)]
