Selenium Python：列印元素的文本屬性

我想瀏覽一個網站，找到一個元素并列印它。

Python版本：3.10；Selenium Webdriver：火狐；IDE：PyCharm 2021.3.2（CE）；作業系統：Fedora 35 虛擬機

我能夠導航到在下拉選單中生成文本的相應頁面。當我通過 CSS 選擇器找到元素并嘗試列印它時，輸出會列印文本“無”。我希望它列印計劃名稱，在這種情況下是“雙重完整計劃 1 ”。該元素并不總是存在，因此我還需要捕獲任何例外。

我要列印的元素的相關 HTML 代碼：

<span class="OSFillParent" data-expression="" style="font-size: 12px; margin-top: 5px;">Dual Complete Plan 1</span>

我要列印的元素的更多 HTML 代碼（我要捕獲的元素低于第四個 div）：

<td data-header="Plan Name">
    <div id="b8-b40-l1_0-132_0-$b2" class="OSBlockWidget" data-block="Content.AccordionItem">
    <div id="b8-b40-l1_0-132_0-b2-SectionItem" class="section-expandable  open is--open small-accordion" data-container="" data-expanded="true" aria-expanded="true" aria-disabled="false" role="tab">
        <div id="b8-b40-l1_0-132_0-b2-TitleWrapper" class="section-expandable-title" data-container="" style="cursor: pointer;" role "button" aria-hidden="false" aria-expanmded="true" tabindex="0" aria-controls="b8-b40-l1_0-132_0-b2-Content" EVENT FLEX
            <div id="b8-b40-l1_0-132_0-b2-Title" class="dividers full-width">
                    <span class="OSFillParent" data-expression="" style="font-size: 12px; margin-top: 5px;">Dual Complete Plan 1</span>
            </div>
        <div class="section-expandable-icon" data-container="" aria-hidden="true"
            ::after
        </div>
    </div>
    <div id="b8-b40-l1_0-132_0-b2-ContentWrapper" class="section-expandable-content no-padding is--expanded" data-container="" tabindex="0" aria-hidden="false" aria-labelledby="b8-b40-l1_0-132_0-b2-TitleWrapper"> 
        <div id="b8-b40-l1_0-132_0-b2-Content" role="tabpanel">
            <a data-link="" href="https://www.communityplan.com" target="_blank" title="Click for more information"> EVENT
                <span class="OSFillParent" data-expression="" style="font-size: 12px;">www.CommunityPlan.com</span>
            </a>
            <span class="OSFillParent" data-expression="" style="font-size: 12px:">Phone Number: 8005224700</span>
        </div>
    </div>
</div>
</div>
</td>

我的相關硒代碼：

# Find the Plan Name & if present set it to the variable "Advantage"
        try:
            Advantage = (WebDriverWait(driver, 5).until(
            EC.presence_of_element_located((By.CSS_SELECTOR, "#b8-b40-l1_0-132_0-b2-Title > span:nth-child(1)"))).get_attribute("value"))
        except:
            pass

print('\033[91;46m', Advantage, '\033[0m')

I expect the output to be "Dual Complete Plan 1", which is what I see on the screen and in the HTML. Instead I get the following:

None

Apparently the "Advantage" variable is being set to "None". Why? I can see the text "Dual Complete Plan 1" that I want to print in the HTML code above. What am I doing wrong? I feel like I need a primer on "get attribute"?

uj5u.com熱心網友回復：

要獲取Dual Complete Plan 1您需要使用的文本

element.text

要么

element.get_attribute("innerHTML")

要么

element.get_attribute("textContent")

而不是presence_of_element_located()使用visibility_of_element_located()

并遵循css selector以識別

div[id*='Title'] > span.OSFillParent

要么

div.dividers.full-width > span.OSFillParent

代碼：

        try:
            Advantage = WebDriverWait(driver, 5).until(
            EC.visibility_of_element_located((By.CSS_SELECTOR, "div[id*='Title'] > span.OSFillParent"))).text
        except:
            pass
        print(Advantage )
