You want to load text from multiple web pages using WebBaseLoader. Which approach correctly loads texts from two URLs and combines their content into a single string?
Aloader1 = WebBaseLoader("https://site1.com") loader2 = WebBaseLoader("https://site2.com") docs = loader1.load() + loader2.load() combined_text = "".join(doc.page_content for doc in docs)
Bloader = WebBaseLoader(["https://site1.com", "https://site2.com"]) docs = loader.load() combined_text = " ".join(docs.page_content)
Cdocs = WebBaseLoader.load("https://site1.com", "https://site2.com") combined_text = " ".join(doc.page_content for doc in docs)
Dloader = WebBaseLoader("https://site1.com") combined_text = loader.load("https://site2.com")
Step-by-Step Solution
Solution:

  1. Step 1: Understand WebBaseLoader usage for multiple URLs

    WebBaseLoader accepts one URL per instance. To load multiple pages, create separate loaders and load each.

  2. Step 2: Combine loaded documents correctly

    loader1 = WebBaseLoader("https://site1.com") loader2 = WebBaseLoader("https://site2.com") docs = loader1.load() + loader2.load() combined_text = "".join(doc.page_content for doc in docs) creates two loaders, loads documents from each, concatenates the lists, then joins their text content into one string.

  3. Step 3: Identify why other options fail

    loader = WebBaseLoader(["https://site1.com", "https://site2.com"]) docs = loader.load() combined_text = " ".join(docs.page_content) incorrectly passes a list of URLs to one loader (not supported). docs = WebBaseLoader.load("https://site1.com", "https://site2.com") combined_text = " ".join(doc.page_content for doc in docs) calls load as a class method with multiple URLs (invalid). loader = WebBaseLoader("https://site1.com") combined_text = loader.load("https://site2.com") tries to pass a URL to load() method (load() takes no arguments).

  4. Final Answer:

    loader1 = WebBaseLoader("https://site1.com") loader2 = WebBaseLoader("https://site2.com") docs = loader1.load() + loader2.load() combined_text = "".join(doc.page_content for doc in docs) -> Option A

  5. Quick Check:

    One loader per URL, then combine texts = A [OK]
Quick Trick: Create one loader per URL, then merge results [OK]
Common Mistakes:
  • Passing multiple URLs to one WebBaseLoader instance
  • Calling load() with URL arguments
  • Trying to load multiple pages with one call
