Extracting all headlines from a news website

You want to extract all the main headlines from a news website using IMPORTXML. The headlines are inside <h2> tags with class 'headline'. Which formula will correctly extract these headlines?

A =IMPORTXML("https://example-news.com", "//div[@class='headline']")

B =IMPORTXML("https://example-news.com", "//h2[@class='headline']")

C =IMPORTXML("https://example-news.com", "//h1[@class='headline']")

D =IMPORTXML("https://example-news.com", "//headline")

💡 Hint

Remember that IMPORTXML uses XPath syntax to select elements by tag and attribute.

The correct XPath to select all <h2> tags with class 'headline' is //h2[@class='headline']. Option B uses this correctly. Other options select wrong tags or non-existent tags.

Extracting all links from a webpage

You want to get all URLs from the links (<a> tags) on a webpage using IMPORTXML. Which formula will return the href attribute of all <a> tags?

A =IMPORTXML("https://example.com", "//href")

B =IMPORTXML("https://example.com", "//a/href")

C =IMPORTXML("https://example.com", "//a/@href")

D =IMPORTXML("https://example.com", "//a[href]")

💡 Hint

To get attribute values in XPath, use @attribute_name.

Option C correctly uses //a/@href to select the href attribute of all <a> tags. Other options use invalid XPath syntax or select wrong nodes.

❓ Function Choice

Choosing the right XPath to extract product prices

A webpage shows product prices inside <span> tags with class 'price'. Which XPath expression will correctly extract all prices using IMPORTXML?

A //span[@class='price']

B //span[class='price']

C //span[@class=price]

D //span[@class='Price']

💡 Hint

XPath attribute values must be in quotes and attribute name is case-sensitive.

Option A uses correct XPath syntax with attribute selector and quotes. Option A misses @, C misses quotes, D uses wrong case for class value.

🎯 Scenario

Handling dynamic content with IMPORTXML

You try to use IMPORTXML to get data from a webpage, but the formula returns #N/A with 'Imported content is empty'. The webpage content is loaded dynamically by JavaScript after page load. What is the best explanation?

A IMPORTXML cannot extract data generated by JavaScript after page load because it fetches only static HTML.

B The XPath expression is incorrect and does not match any elements.

C The website blocks IMPORTXML requests with a firewall.

D The spreadsheet has reached its formula limit and cannot process more IMPORTXML calls.

💡 Hint

Think about how IMPORTXML fetches webpage data and what it can see.

IMPORTXML fetches the static HTML source only. It cannot see content loaded later by JavaScript, so it returns empty results if data is dynamic.

Counting the number of items extracted by IMPORTXML

You use the formula =IMPORTXML("https://example.com/products", "//div[@class='item-name']") to get product names. The result fills cells A1:A10. What is the formula to count how many product names were extracted?

A =ROWS(A1:A10)

B =COUNT(A1:A10)

C =COUNTIF(A1:A10, "*")

D =COUNTA(A1:A10)

💡 Hint

Think about which function counts non-empty cells regardless of data type.

COUNTA counts all non-empty cells including text. COUNT counts only numbers, so it would miss text product names. COUNTIF with "*" also counts non-empty text but COUNTA is simpler. ROWS counts total rows regardless of content.

Practice

1. What does the IMPORTXML function do in Google Sheets?

easy

A. It fetches data from a web page using a URL and XPath query.

B. It imports data from another Google Sheet only.

C. It creates charts based on web data automatically.

D. It exports your sheet data to a web page.

Solution

1. Step 1: Understand IMPORTXML purpose

   IMPORTXML is designed to pull data from web pages by using a URL and an XPath query to specify what data to extract.

2. Step 2: Compare options

   Only "It fetches data from a web page using a URL and XPath query." correctly describes this function. The other options describe unrelated features.

3. Final Answer:

   It fetches data from a web page using a URL and XPath query. -> Option A

4. Quick Check:

   IMPORTXML = fetch web data [OK]

Hint: IMPORTXML grabs web data using URL + XPath [OK]

Common Mistakes:

• Thinking IMPORTXML only works with other sheets
• Confusing IMPORTXML with chart creation
• Assuming it exports data instead of importing

2. Which of these is the correct syntax for using IMPORTXML to get all <h2> elements from a webpage URL in cell A1?

easy

A. =IMPORTXML(A1, "//h2/@text")

B. =IMPORTXML(A1, "//h2[]")

C. =IMPORTXML(A1, "h2")

D. =IMPORTXML(A1, "//h2")

Solution

1. Step 1: Recall IMPORTXML syntax

   The function takes two arguments: a URL and an XPath query. To select all <h2> elements, the XPath is "//h2".

2. Step 2: Evaluate options

   =IMPORTXML(A1, "//h2") uses correct XPath syntax. =IMPORTXML(A1, "//h2[]") has invalid brackets. =IMPORTXML(A1, "h2") misses the XPath axis. =IMPORTXML(A1, "//h2/@text") tries to get an attribute "text" which doesn't exist.

3. Final Answer:

   =IMPORTXML(A1, "//h2") -> Option D

4. Quick Check:

   Correct XPath syntax = =IMPORTXML(A1, "//h2") [OK]

Hint: Use double slashes and tag name for XPath [OK]

Common Mistakes:

• Adding brackets [] incorrectly in XPath
• Omitting // in XPath
• Trying to get text as attribute with @text

3. Given the formula =IMPORTXML("https://example.com", "//ul/li"), what will the output be?

medium

A. All paragraphs (<p>) from the page.

B. Only the first list item from the page.

C. All list items (<li>) inside unordered lists (<ul>) from the page.

D. An error because XPath is invalid.

Solution

1. Step 1: Understand the XPath query

   The XPath "//ul/li" selects all
2. elements that are children of any <ul> element on the page.

3. Step 2: Predict IMPORTXML output

   IMPORTXML will return all matching list items, not just the first, and it won't return paragraphs or error since XPath is valid.

4. Final Answer:

   All list items (
5. ) inside unordered lists (<ul>) from the page.
-> Option C

6. Quick Check:

   XPath selects all matching nodes = All list items (
7. ) inside unordered lists (<ul>) from the page. [OK]

Hint: XPath //ul/li selects all list items under ul [OK]

Common Mistakes:

• Assuming only first match is returned
• Confusing <li> with <p> tags
• Thinking XPath syntax is wrong here

4. You wrote =IMPORTXML("https://example.com", "//div[@class='price']") but get a #N/A error. What is the likely problem?

medium

A. The URL is invalid or unreachable.

B. The XPath syntax for class attribute is incorrect.

C. IMPORTXML does not support attribute filters.

D. You must use single quotes inside the XPath instead of double quotes.

Solution

1. Step 1: Check XPath syntax

   The XPath "//div[@class='price']" is correct for selecting divs with class 'price'.

2. Step 2: Consider other causes of #N/A

   #N/A often means the URL is unreachable or blocked. IMPORTXML supports attribute filters and double quotes inside XPath strings are allowed if escaped properly.

3. Final Answer:

   The URL is invalid or unreachable. -> Option A

4. Quick Check:

   #N/A often means URL problem [OK]

Hint: Check URL accessibility if #N/A error occurs [OK]

Common Mistakes:

• Assuming XPath syntax is wrong when it's correct
• Not verifying the URL is accessible
• Thinking IMPORTXML can't filter by attributes

5. You want to import the latest news headlines from https://news.example.com where headlines are in <h3 class='headline'> tags. Which formula correctly imports only the text of these headlines?

hard

A. =IMPORTXML("https://news.example.com", "//h3[@class='headline']")

B. =IMPORTXML("https://news.example.com", "//h3[@class='headline']/text()")

C. =IMPORTXML("https://news.example.com", "//h3[@class='headline']/@text")

D. =IMPORTXML("https://news.example.com", "//h3[@class='headline']/innerText")

Solution

1. Step 1: Understand XPath to get text content

   To get only the text inside elements, use the XPath function /text() after selecting the element.

2. Step 2: Evaluate options

   =IMPORTXML("https://news.example.com", "//h3[@class='headline']/text()") correctly uses /text(). =IMPORTXML("https://news.example.com", "//h3[@class='headline']") returns the whole element including tags. =IMPORTXML("https://news.example.com", "//h3[@class='headline']/@text") tries to get an attribute 'text' which doesn't exist. =IMPORTXML("https://news.example.com", "//h3[@class='headline']/innerText") uses invalid XPath syntax.

3. Final Answer:

   =IMPORTXML("https://news.example.com", "//h3[@class='headline']/text()") -> Option B

4. Quick Check:

   Use /text() to get element text [OK]

Hint: Add /text() to XPath to get only text content [OK]

Common Mistakes:

• Omitting /text() and getting full HTML tags
• Using @text which is not an attribute
• Trying invalid XPath like innerText
