An example of an AI chatbot conversation about advanced XPath techniques and usage.
What are some advanced techniques for using XPath?
Advanced XPath techniques include using axes, predicates, and functions like 'contains()' and 'starts-with()'.
Can you explain how to use the 'contains()' function in XPath?
Sure! The 'contains()' function checks if a string contains a specific substring. For example, //book[contains(title, 'AI')] selects books with 'AI' in their title.
What are some common mistakes to avoid when using XPath?
Common mistakes include not using the correct axes, misunderstanding the context of nodes, and failing to account for namespaces.
How can I optimize my XPath queries for better performance?
To optimize XPath queries, minimize the use of wildcards, avoid deep traversals, and use indexed attributes when possible.
