python selenium - 获取链接的文本（a）

Question

How do I get the text: "THIS TEXT"

Here is what I have tried:

elem = browser.find_element_by_css_selector('td.mainContent > a')
print(elem.text)

This left me really confused since I was sure that this would find the text of that a, but it didn't. (I didn't get any error tough.. which is wierd)

the html code: (search for "THIS TEXT" to find it in the html.)

Jeg opdagede at jeg havde skaffet det forkerte tastetur, der var ment som gave. Og siden at jeg havde ventet for længe med at få den byttet, var det altså for sent. Derfor sælger jeg den så for 1900 kr. (300 mindre en nypris)

Answer 1

try this

elem = browser.find_element_by_xpath('//td[@class='mainContent']/a')
print(elem.text)

Answer 2

It seems that you use wrong selector. Try following:

elem = browser.find_element_by_css_selector('div.expandable-box.expandable-box-collapsed > a.listingLink')
print(elem.text)

UPDATE

Your selector td.mainContent > a points to direct child of <td class="mainContent"> and this is

<a class="listingLink" href="http://www.dba.dk/tastatur-mad-catz-strike-7/id-1029751995/">
        <span class="headline-block"></span>
</a>

As you can see, it contains no text node
