What is XPath and how to use it with an XML document?
XPath is a query language used to navigate and select elements and attributes in XML documents, locating nodes through path expressions. It treats XML as a node tree, supports multiple axes (such as child, parent, attribute) and functions (such as contains, position), and can accurately select the required data. For example, /books/book[@id='1'] selects the book element with id 1, //author[text()='JaneSmith'] selects the author element whose text is JaneSmith. In Python's lxml library, tree.xpath() can be used to perform queries and is widely used in XSLT.

How to display raw XML in an HTML page?
The answer is by escaping special characters and displaying the raw XML using HTML entities. Specific methods include: replacing, &, ", ' with "&, ", ' respectively, and then wrapping them with tags to preserve the format. Optional JavaScript dynamic escaping ensures that the browser renders it as plain text rather than parsing it as a markup.

How to convert a JSON object to an XML string?
To convert a JSON object into an XML string, its hierarchical structure needs to be mapped into XML elements and attributes. You can use JavaScript's js2xmlparser library or Python's dicttoxml library to implement automated conversion, or you can manually process objects, arrays, and basic types through recursive functions. For example, in JavaScript, js2xmlparser.parse("person",{name:"John"}) will generate John; in Python, dicttoxml({"person":{"name&q

How to parse XML with namespaces in Python?
Proper handling of namespace URIs is key to parsing namespaced XML. When using xml.etree.ElementTree, you need to define a namespace mapping, such as {'ns':'http://example.com/ns'}, and pass it in through the namespaces parameter when searching for elements; you also need to specify a prefix for the default namespace; the lxml library provides a more concise syntax and supports XPath and curly braces to directly write URIs to improve flexibility.
