What is the name of the method that allows XPath expressions in SimpleXML?

• A. query
• B. xpath
• C. select
• D. extract

Answer: (B)

The method that allows XPath expressions in SimpleXML is known as xpath. This method enables users to execute XPath queries directly on SimpleXML objects, which is a powerful capability for navigating and extracting data from XML structures. When you call the xpath method on a SimpleXML object, you can pass a string that contains the XPath expression. The method then evaluates this expression against the XML data represented by the SimpleXML object and returns an array of matching nodes. This functionality is particularly useful for retrieving specific elements or attributes from complex XML documents. Using xpath with SimpleXML provides a straightforward and efficient way to access desired parts of the XML content without the need for more complex DOM manipulation techniques.
