Iterate through table rows and print column text with Python Selenium

问题

I have a table (<table>) with values in each row (<tr>) from its body (<tbody>).

The value I would lile to print out is in the <span> inside a <div> tag.

Inspecting the html, I see the value e.g. "Name" is in row 1 (tr[1]), column 2 (td[2]):

<tr class="GAT4PNUFG GAT4PNUMG" __gwt_subrow="0" __gwt_row="0">
            <td class="GAT4PNUEG GAT4PNUGG GAT4PNUHG GAT4PNUNG">
            <td class="GAT4PNUEG GAT4PNUGG GAT4PNUNG">
                <div __gwt_cell="cell-gwt-uid-324" style="outline-style:none;">
                    <span class="linkhover" title="Name" style="white-space:nowrap;overflow:hidden;text-overflow:ellipsis;empty-cells:show;display:block;color:#00A;cursor:pointer;">Name</span>
                </div>
            </td>

I would like to loop through the table each row and print out the value in columns 2, td[2]

I am using Python with Selenium Webdriver

The full Xpath to the table row 1, column 2 is:

html/body/div[2]/div[2]/div/div[4]/div/div[2]/div/div[3]/div/div[5]/div/div[3]/div/div[4]/div/div[2]/div/div[4]/div/div[3]/div/div[2]/div/div/table/tbody/tr[1]/td[2]/div/span

I was thinking if i can start from the table, xpath as follows:

html/body/div[2]/div[2]/div/div[4]/div/div[2]/div/div[3]/div/div[5]/div/div[3]/div/div[4]/div/div[2]/div/div[4]/div/div[3]/div/div[2]/div/div/table/tbody

I can then use a for loop and use an index for the tr and td e.g for row1 use tr[i], for col2 use td[2].

html/body/div[2]/div[2]/div/div[4]/div/div[2]/div/div[3]/div/div[5]/div/div[3]/div/div[4]/div/div[2]/div/div[4]/div/div[3]/div/div[2]/div/div/table/tbody/tr[i]/td[2]/div/span

How can i loop through this table and print out the value of the Span class tag which is always in column 2 of the table?

I tried to get the start of the table into a variable and then I could maybe use this to loop through the rows and columns. I need some help please.

table = self.driver.find_element(By.XPATH, 'html/body/div[2]/div[2]/div/div[4]/div/div[2]/div/div[3]/div/div[5]/div/div[3]/div/div[4]/div/div[2]/div/div[4]/div/div[3]/div/div[2]/div/div/table/tbody')

Here's the full HTML:

    <table cellspacing="0" style="table-layout: fixed; width: 100%;">
    <colgroup>
    <tbody>
        <tr class="GAT4PNUFG GAT4PNUMG" __gwt_subrow="0" __gwt_row="0">

            <td class="GAT4PNUEG GAT4PNUGG GAT4PNUNG">
                <div __gwt_cell="cell-gwt-uid-324" style="outline-style:none;">
                    <span class="linkhover" title="Name" style="white-space:nowrap;overflow:hidden;text-overflow:ellipsis;empty-cells:show;display:block;color:#00A;cursor:pointer;">Name</span>
                </div>
            </td>
            <td class="GAT4PNUEG GAT4PNUGG GAT4PNUNG">

                </div>
            </td>
            <td class="GAT4PNUEG GAT4PNUGG">
            <td class="GAT4PNUEG GAT4PNUGG">
            <td class="GAT4PNUEG GAT4PNUGG">
            <td class="GAT4PNUEG GAT4PNUGG GAT4PNUBH">
        </tr>
        <tr class="GAT4PNUEH" __gwt_subrow="0" __gwt_row="3">
            ---
        <tr class="GAT4PNUFG" __gwt_subrow="0" __gwt_row="4">

The developer has put an ID into the table. I have it working now. It is printing all the cell values from column 2. The code is:

table_id = self.driver.find_element(By.ID, 'data_configuration_feeds_ct_fields_body0')
rows = table_id.find_elements(By.TAG_NAME, "tr") # get all of the rows in the table
for row in rows:
    # Get the columns (all the column 2)        
    col = row.find_elements(By.TAG_NAME, "td")[1] #note: index start from 0, 1 is col 2
    print col.text #prints text from the element

The XPath you currently using is quite fragile since it depends on the complete document structure and the relative position of the elements. It can easily break in the future.

Instead, locate the rows using their class or other attributes. For instance:

for row in driver.find_elements_by_css_selector("tr.GAT4PNUFG.GAT4PNUMG"):
    cell = row.find_elements_by_tag_name("td")[1]
    print(cell.text)
