如何在Groovy中解析XML注释？

Question

Is there any way to parse XML comments in Groovy? 在Groovy中有什么方法可以解析XML注释？

Both XMLParser and XMLSluprer don't seem to support comments nodes. XMLParser和XMLSluprer似乎都不支持注释节点。

Suppose following file (example.html): 假设以下文件（example.html）：

 <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>title</title> <body> <table cellpadding="1" cellspacing="1" border="1"> <thead> <tr><td rowspan="1" colspan="3">title</td></tr> </thead><tbody> <!--I cannot be seen--> <tr> <td>x</td> <td>x</td> <td>x</td> </tr> </tbody></table> </body> </html>

Here is my code: 这是我的代码：

def parser = new XmlSlurper(false, false)
parser.setFeature("http://apache.org/xml/features/disallow-doctype-decl", false)
parser.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false)

def response = parser.parse('example.html')

And when I use 当我使用

println XmlUtil.serialize(response)

to output the file, no comment can be seen. 输出文件，看不到注释。

as soon as you have html - it's possible to use jsoup to parse 一旦有了html，就可以使用jsoup进行解析

@Grab(group='org.jsoup', module='jsoup', version='1.11.3')
import org.jsoup.Jsoup
import org.jsoup.nodes.Document

def html = '''<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>title</title>
<body>
<table cellpadding="1" cellspacing="1" border="1">
<thead>
<tr><td rowspan="1" colspan="3">title</td></tr>
</thead><tbody>
<!--I cannot be seen-->
<tr>
    <td>x</td>
    <td>x</td>
    <td>x</td>
</tr>
</tbody></table>
</body>
</html>'''

Document doc = Jsoup.parse(html)
println doc.select('html body table tbody').first()?.childNodes()?.find{it.nodeName()=='#comment'}?.getData()
