Get next element with after each element matching a specific class name-CodePudding

Set-up

I have the following html table,

<table>
    <tbody>
        <tr >
        <tr >
        <tr >
        <tr >
        <tr >
        <tr >
        <tr >
        <tr >
        <tr >
        <tr >
        <tr >
        <tr >
        <tr >
        <tr >
    <tbody>
</table>

I need ONLY the information in the rows with class names "order-activ_order_delivered" and "tracking-url tracking-url-activ_order_delivered".

Moreover, the information of any "order-activ_order_delivered" row is related with the subsequent "tracking-url tracking-url-activ_order_delivered" row.

Code so far

The following loop gets each "order-activ_order_delivered",

order_table = el_css(browser,'#my-orders-table > tbody')

for order in order_table.find_elements(By.CSS_SELECTOR,
                           "tr[class^='order-activ_order_delivered']"):
    #code to get data from row

Question

To get the information of the subsequent "tracking-url tracking-url-activ_order_delivered" row I tried,

for order in order_table.find_elements(By.CSS_SELECTOR,
                           "tr[class^='order-activ_order_delivered']"):
    
    order_table.find_elements(By.CSS_SELECTOR,
                           "tr[class^='order-activ_order_delivered']/following-sibling::tr")

but this gives an InvalidSelectorException: invalid selector: An invalid or illegal selector was specified (Session info: chrome=100.0.4896.127)

Either because you can't use following-sibling on a CSS_SELECTOR or because something else.

How do I get the from the subsequent "tracking-url tracking-url-activ_order_delivered" row?

CodePudding user response：

following-sibling is not CSS_Selector syntax it is xpath syntax.

Your code should be like identify the specific element and then using xpath to check the following-sibling

 for order in order_table.find_elements(By.CSS_SELECTOR,
                           "tr[class^='order-activ_order_delivered']"):

      nextelement=order.find_element(By.XPATH, "./following-sibling::tr[@class='tracking-url tracking-url-activ_order_delivered']")

for order in order_table.find_elements(By.CSS_SELECTOR,
                               "tr[class^='order-activ_order_delivered']"):
    
          nextelement=order.find_element(By.XPATH, "./following-sibling::tr[1]")

In case of want to use css selector use can use this which will return all tracking-url.

tr[class^='order-activ_order_delivered'] tr.tracking-url.tracking-url-activ_order_delivered

Code:

for order in order_table.find_elements(By.CSS_SELECTOR,
                           "tr[class^='order-activ_order_delivered'] tr.tracking-url.tracking-url-activ_order_delivered"):
    nextelement=order
