How can I write an XPath expression to search for a specific product?

In the context of selenium, to solve this problem you would need to understand how you can navigate the XML or the HTML document structure by using the Xpath specifically using the “following -sibling” axis.

Xpath is a powerful language to select nodes in an XML document. The “following sibling” axis is used to select all the sibling nodes that would appear after the current node in the document.

Here is the step-by-step approach given to how you can construct the XPath expression for this particular scenario:-

Locating the cell with the product name

You would first need to locate the element which contains the text content related to product A. This can be achieved by using the text () function in Xpath.

Selection of the following siblings

Once you have identified the element which contains product A you can use the “following siblings” axis to select the subsequent element which contains the price.

Here Is the full implementation of the coding given:-

Import requests

From bs4 import BeautifulSoup

From lxml import etree

# Step 1: Fetch the Webpage

url = ‘https://example.com/products’  # Replace with the actual URL

response = requests.get(url)

web_content = response.content

# Step 2: Parse the HTML Content

Soup = BeautifulSoup(web_content, ‘html.parser’)

Html = soup.prettify()  # Get a formatted string of the parsed HTML

# Step 3: Convert HTML to lxml Object

Parser = etree.HTMLParser()

Tree = etree.fromstring(html, parser)

# Step 4: Define XPath Expression

Xpath_expression = “//td[text()=’Product A’]/following-sibling::td[1]”

# Step 5: Execute XPath Expression

Price_element = tree.xpath(xpath_expression)

# Step 6: Extract and Print the Price

If price_element:

    Price = price_element[0].text

    Print(f”The price of Product A is: {price}”)

Else:

    Print(“Product A not found or no price available.”)

Here is the example given in python programming language:-

From lxml import html

Import requests

# Fetch the webpage

url = ‘https://example.com/products’  # Replace with the actual URL

response = requests.get(url)

web_content = response.text

# Parse the HTML content

Tree = html.fromstring(web_content)

# Define the XPath expression to select the price of “Product A”

Xpath_expression = “//td[text()=’Product A’]/following-sibling::td[1]”

# Execute the XPath expression

Price_element = tree.xpath(xpath_expression)

# Extract and print the price

If price_element:

    Price = price_element[0].text_content().strip()

    Print(f”The price of Product A is: {price}”)

Else:

    Print(“Product A not found or no price available.”)
