In Python, you can use the etree module from the lxml library to parse data. Here is a simple example of parsing data using XPath.<\/p>\n

from<\/span> lxml import<\/span> etree\r\n\r\n# \u521b\u5efa\u4e00\u4e2aXML\u6587\u6863\u5e76\u89e3\u6790<\/span>\r\nxml_data = \"\"\"\r\n<books>\r\n    <book>\r\n        <title>Python Cookbook<\/title>\r\n        <author>David Beazley<\/author>\r\n        <year>2013<\/year>\r\n    <\/book>\r\n    <book>\r\n        <title>Fluent Python<\/title>\r\n        <author>Luciano Ramalho<\/author>\r\n        <year>2015<\/year>\r\n    <\/book>\r\n<\/books>\r\n\"\"\"<\/span>\r\nroot = etree.fromstring(xml_data)\r\n\r\n# \u4f7f\u7528XPath\u9009\u62e9\u5143\u7d20<\/span>\r\ntitles = root.xpath(\"\/\/title\/text()\"<\/span>)\r\nauthors = root.xpath(\"\/\/author\/text()\"<\/span>)\r\nyears = root.xpath(\"\/\/year\/text()\"<\/span>)\r\n\r\n# \u6253\u5370\u89e3\u6790\u7ed3\u679c<\/span>\r\nfor<\/span> title, author, year in<\/span> zip<\/span>(titles, authors, years):\r\n    print<\/span>(f\"Title: {title}<\/span>\"<\/span>)\r\n    print<\/span>(f\"Author: {author}<\/span>\"<\/span>)\r\n    print<\/span>(f\"Year: {year}<\/span>\"<\/span>)\r\n    print<\/span>(\"---\"<\/span>)\r\n<\/code><\/pre>\n
The output is as follows:<\/p>\n

In the example above, the XML string is parsed into an Element object using the etree.fromstring() method. Then, the xpath() method is used to select the corresponding elements using XPath expressions. Finally, the text property is used to retrieve the text content of the elements.<\/p>\n","protected":false},"excerpt":{"rendered":"
