如何从LinkedIn板块抓取帖子日期并获取指定文本的正确XPath？

Hey Jacek, let's work through how to correctly target that "2 dni temu" timestamp text from LinkedIn posts. The issue with your initial XPath is that the occludable-update ember-view element is just the top-level container for the post—your target timestamp is nested several layers deeper inside it, so we need to drill down to the right child element.

Here are a few reliable approaches using class-based targeting:

方案1：基于时间元素的特征类定位 #

LinkedIn consistently uses a set of small-text style classes for timestamps (like t-12, t-normal, t-black--light). We can combine these with the post container to grab the first post's timestamp:

//div[contains(@class, 'occludable-update ember-view')][1]//span[contains(@class, 't-12 t-normal t-black--light')]/text()

为什么这个有效： #

• contains(@class, ...) avoids issues with dynamic suffixes LinkedIn sometimes adds to class names (like random ember-view identifiers).
• We first target the first post container with [1], then traverse down to the span that holds the timestamp text.

方案2：精准匹配时间文本内容 #

Since you're targeting Polish-language timestamps ("dni temu" = "days ago"), we can add a text check to ensure we don't grab other secondary text in the post header:

//*[@class="occludable-update ember-view"][1]//*[contains(@class, 'update-components-actor__sub-description')]//span[contains(text(), 'dni temu')]/text()

额外提示： #

• Always verify the current DOM structure using your browser's dev tools (F12): Right-click the timestamp, select "Inspect", then check the element's class names—LinkedIn occasionally updates these, so you might need to tweak the class strings.
• Avoid using absolute XPaths (like /html/body/div[4]/...)—these break instantly if LinkedIn adjusts page layout. Stick to relative paths with class-based targeting.
• If you're using a scraping tool (Selenium, Scrapy, etc.), make sure you're complying with LinkedIn's Terms of Service to avoid being blocked.
