以下是关于CDATA在XML中的用法：一、基本用法 1. 在XML中，CDATA就像是一个安全的小盒子。比如说，我想在XML文档里包含一段JavaScript代码，直接写的话可能会被XML解析器误读。但是把代码放在<![CDATA[和]]>之间就安全了。像这样：<![CDATA[var x = 5; alert(x); ]]>。这就好比把宝贝（代码）放在一个...
from lxml import etree # 读取XML文档 xml_doc = etree.parse("example.xml") # 遍历XML文档中的所有元素 for elem in xml_doc.iter(): # 判断元素是否包含CDATA段 if elem.text is not None and "<![CDATA[" in elem.text: # 获取CDATA段内容 cdata_content = elem.text.replace("<![CDATA[", ...
</example> </sample> 复制代码 使用CDATA 如 清单 3 中的简单示例所示,CDATA 区域的起始标记是一个特殊的序列 <![CDATA[,结束标记是 ]]> 序列。这些标记之间的任何内容都将原封不动地通过 XML 解析器。有些开发平台拥有特殊的 CDATA 对象(比如 XML DOM 中的 CDATASection)来表示 CDATA 区域中的内容,但其...

下面是使用BeautifulSoup从XML文件中读取CDATA的步骤: 导入BeautifulSoup库: 代码语言:txt 复制 from bs4 import BeautifulSoup 读取XML文件: 代码语言:txt 复制 with open('example.xml', 'r') as file: xml_data = file.read() 这里假设XML文件名为example.xml,你需要将其替换为实际的文件名。
In this example, we have a block of JavaScript code inside an XHTML document. If you've been involved in web development, you'll probably know how common JavaScript is on the web. You might also know that any block of JavaScript code could contain all sorts of potentially problematic charac...

在这种情况下,您的数据包含大量字符,其中包括‘&’和‘<’,但是这些字符不应该是XML。比较:<example-code>while (x < len && !done) { print( "Still working, 'zzz'." ); &...
