如何编写在两个不同级别选择属性值的 XPath

Question

There are 2 tables and I need to select the "date1" text which might be in the tr/td/a in the 1st table or tr/td in the 2nd table. How to write a xpath for this kind of scenario?

<div>
    <table>
       <tbody>
           <tr>
             <td id="1">
                <a style="font-style:normal;font-weight:bold;" onclick="return" class="PTL"> </a>
             </td>  
             <td id="1">
                <a style="font-style:normal;font-weight:bold;" onclick="return" class="PTL">date1</a>
             </td>  
             <td id="1">
                <a style="font-style:normal;font-weight:bold;" onclick="return" class="PTL">date1</a>
             </td>
             <td id="1">
                <a style="font-style:normal;font-weight:bold;" onclick="return" class="PTL">date2</a>
             </td>
             <td id="1">
                <a style="font-style:normal;font-weight:bold;" onclick="return" class="PTL">date3</a>
             </td>
           </tr>
       </tbody>
    </table>
    <table>
       <tbody>
           <tr>
              <td id="1" style="font-style:normal;font-weight:bold;" class="PTCH"> </td>
              <td id="1" style="font-style:normal;font-weight:bold;" class="PTCH">date1</td>
              <td id="1" style="font-style:normal;font-weight:bold;" class="PTCH">date2</td>
              <td id="1" style="font-style:normal;font-weight:bold;" class="PTCH">date3</td>
           </tr>
       </tbody>
    </table>
</div>

I tried this but this select the entire row. I want to select a specific column

xpath=(//table)[2]//tr[td[contains(text(),'date1') and not(text()=' ')] or td/a[contains(text(),'date1') and not(text()=' ')]]

Answer 1

In the answer you posted, you are actually selecting a td element. You say you want to select the "date1" text, but there is no point in selecting the text if you already know what it is.

The following is a simpler approach to what you've posted:

//table//tr/td[contains(., 'date1')]

Or if you only want to include the first table (as you're doing in your post):

(//table)[1]//tr/td[contains(., 'date1')]

Regarding your comment below, if you want to find a value that is in an attribute, do this:

(//table)[1]//tr/td[descendant-or-self::*[contains(@style, 'bold')]]

Or if you want to select the actual element that has the style attribute with bold in it:

(//table)[1]//tr/td/descendant-or-self::*[contains(@style, 'bold')]

Answer 3

After number of attempts I came up with this and its working as I needed. Thanks all.

xpath=(//table)[1]//tr/td[contains(text(),'date1') and not(text()=' ') or a[contains(text(),'date1') and not(text()=' ')]]
