How to get data from a specific row within an html table by using selenium webdriver in python

Question

I am completely new to python and selenium, so please forgive all the mistakes and erroneous assumptions.

I try to get a certain value from an html table that is always in column 4 while the row may change depending on the search result. The html code is built in a way that each tr has a th scope="row" as a child and then also 4 tds as children on the same level. Now what my code needs to do is: find the tr where th scope="row"="MyString" and then go into column 4, so td[4], and then output the th of that row again and the value in td[4].

Here is the html code

<div id="ctl00_ContentPlaceHolder1_dvDetailsTableAmbulantMisc">

                <table class="details-table ambulant misc nophone" role="grid">
                    <thead>
                        <tr role="row">
                            <th scope="col">Bezeichnung</th><th role="gridcell"></th>
                            <th scope="col">Kategorie</th><th role="gridcell"></th>
                            <th scope="col">Preis</th>
                        </tr>
                    </thead>
                    <tbody>

                <tr>
                    <th scope="row">Ganzwaschung</th><td></td>
                    <td>Körperbezogene Pflegemaßnahmen</td><td></td>
                    <td id="ctl00_ContentPlaceHolder1_lvDetailsTableAmbulantMisc_ctrl0_tdPreis1">24,39</td>

                </tr>

How would I go about doing this? If you want I can also share my code that shows how to get to the table.

Answer 1

You could do something like this...

rows = driver.find_elements_by_css_selector('.details-table tbody>tr')
row = next(filter(lambda x: x.find_element_by_xpath('th[1]').text == 'MyString', rows))
value = row.find_element_by_xpath('td[4]').text

rows gets you all the rows.
row does a filter and find the first th foreach row that matches MyString then returns that row (so we are still at the tr level).
value then does a find element on that tr by finding td[4] and gets the text
