What is the output of the provided PHP code that loads a specific XML and queries it with XPath?

• A. James
• B. Dido
• C. Leila
• D. George

Answer: (B)

To determine the output of the PHP code that loads a specific XML and queries it with XPath, it is essential to understand how the parsing and querying process works. In this scenario, the PHP code likely uses `simplexml_load_string()` or `simplexml_load_file()` to load the XML data and then applies XPath to query for specific nodes. The output of the XPath query directly depends on the structure of the XML and the specific XPath expression used. If the correct answer is "Dido," this indicates that the XPath query successfully targeted a node or attribute within the XML structure that holds the value "Dido." This suggests that in the XML content, there is likely an element or a context where "Dido" is the intended output based on the query. For instance, if the XML looked like this: ```xml <users> <user> <name>James</name> </user> <user> <name>Dido</name> </user> <user> <name>Leila</name> </user> <user> <name>George</name> </user> </users> ``` And the XPath query was something along the lines of
