我在 groovy 中有以下代码片段:
s = '''
<html>
<head>
<title>My title</title>
</head>
<body>
This is body!
</body>
</html>'''
new XmlSlurper().parse(s)
它给出以下异常:
java.net.MalformedURLException: no protocol:
<html>
<head>
<title>My title</title>
</head>
<body>
This is body!
</body>
</html>

为什么在解析 XML 时会出现 MalformedURLException？
最佳答案
当你解析一个字符串时，你需要做:
new XmlSlurper().parseText(s)
代替:
new XmlSlurper().parse(s)
GPathResult parse(String uri): Parse the content of the specified URI into a GPathResult Object.
关于html - 使用 XmlSlurper 时出现 MalformedURLException，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/23359382/
