XML中如何解析XML字符串中的属性_XML解析XML字符串属性的操作方法

import xml.etree.ElementTree as ET
<p>xml_str = '''
<book id="101" category="fiction">
<title>The Great Gatsby</title>
</book>
'''</p><p>root = ET.fromstring(xml_str)
print(root.attrib['id'])        # 输出: 101
print(root.attrib.get('category'))  # 输出: fiction

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse(new InputSource(new StringReader(xmlString)));
<p>NodeList books = doc.getElementsByTagName("book");
for (int i = 0; i < books.getLength(); i++) {
Element book = (Element) books.item(i);
String id = book.getAttribute("id");
String category = book.getAttribute("category");
System.out.println("ID: " + id + ", Category: " + category);
}

const parser = new DOMParser();
const xmlDoc = parser.parseFromString(xmlString, "text/xml");
<p>const book = xmlDoc.querySelector("book");
console.log(book.getAttribute("id"));      // 获取id属性
console.log(book.getAttribute("category")); // 获取category属性
