How to select elements by text in Xpath

In Python, you can use the lxml library along with XPath to select elements by text content. Here's an example of how you can retrieve the title of a web page using lxml and XPath with the website scrapingdog.com as an example:

import requests
from lxml import html

# Send a GET request to the web page
response = requests.get('https://www.scrapingdog.com/')

# Parse the HTML content
page_content = html.fromstring(response.content)

# Extract the title using XPath
title = page_content.xpath('//title/text()')

# Print the title
print(title[0] if title else 'Title not found')

In the above example, we first send a GET request to the web page using the requests library to retrieve the HTML content. Then, we parse the HTML content using html.fromstring() from lxml. Next, we use an XPath expression //title/text() to select the text content of the <title> element, which represents the title of the web page. Finally, we print the extracted title. Note that the [0] indexing is used to access the first item in the list of selected elements, and the conditional expression title[0] if title else 'Title not found' is used to handle cases where the title element is not found in the web page.
