什麼是網頁爬蟲?
假設你的老闆給了你一個任務,他希望你從一個網站上提取大約 1000 個產品,將資料結構化並儲存到資料庫中,你會手動複製貼上所有的產品細節,包括產品名稱、網址和價格?我可以想像你會工作幾天幾夜,但你不會完成這個任務,所以這就是網頁爬蟲的優勢。因此,網頁爬蟲,或網頁採集或網頁資料提取就像寫一個指令碼,可以在幾分鐘內自動從網站上提取資料!。
為什麼是 LXML 而不是 BeautifulSoup?
LXML 是一個輕量級的 HTML 解析器,即使是最流行的網頁抓取框架(Scrapy)也是建立在LXML之上的,BeautifulSoup 在開放給我們的功能數量上有點過剩,它有更多的功能可以使用,是的,沒錯 然而,在Web Scraping中,大多數時候我們使用 XPath 和 CSS 選擇器來瀏覽和選擇要從HTML網頁(樹)中爬取的內容,所以沒有必要學習新的功能,也沒有必要浪費那麼多時間來熟悉 BeautifulSoup 的 API 和內部架構,此外,LXML在效能方面也比BeautifulSoup好得多。

Clean and dry the piece of salmon fillet and make sure it is at room temperature before you start cooking it.

8. 將三文魚放於青豆醬上。淋上酸豆牛油及擠檸檬汁。
Add minted peas to plate, place salmon fillet on top, spoon on the capers and butter mixture. Add a squeeze of the lemon.
Notes from Eddie:
1. Make sure the salmon fillet is in room temperature before you start cooking. I would bring out the fish about an hour before I start cooking.
2. Make sure the fillet is quite dry before you cook. Use a knife to scrape off any excess moisture from the skin.
3. You can use fresh peas if you can find, but frozen one is also fine.
4. Use Canola oil for panfrying salmon fillet. It is better for the recipe as the oil has a higher burning point.
5. While frying the fish, I usually lift the fish to check the skin, you want it to turn golden brown.
關於此食譜 About:
This is one of my favourite ways to eat Salmon. I also like it because it’s quite simple to make. Try your best to buy some good quality salmon, my favourite is King Salmon from New Zealand. My favourite part of the salmon is the belly so make sure you get a piece that includes some belly parts. The most important part of this salmon is making sure that its quite dry before you cook. There is a lot of moisture in the skin and I find the best way is to scrape it off with a knife. Keep scraping till no more moisture comes off the skin of the fish. Dry the other side with some kitchen towel. I prefer not to salt the fish until I cook it as more moisture will come off the fish if you salt it too early.
