如何让Groovy / XMLSlurper从节点剥离html标签？ [英] How keep groovy/XMLSlurper from stripping html tags from a node?
问题描述
我正在从POST响应中读取HTML文件并使用XMLSlurper解析它。这个页面上的textarea节点有一些HTML代码（非urlencoded - 不是我的选择），当我读取该值时，Groovy会去除所有标签。
I'm reading an HTML file from a POST response and parsing it with XMLSlurper. The textarea node on the page has some HTML code put into it (non-urlencoded - not my choice) and when I read that value, Groovy strips all the tags.
示例：
Example:
<html>
<body>
<textarea><html><body>This has html code for some reason</body></html></textarea>
</body>
</html>
当我解析上述内容并找到（...）textarea节点时，它会返回给我：
When I parse the above and then find(...) the "textarea" node, it returns to me:
This has html code for some reason
并且没有标签。如何保留标签？
and none of the tags. How do I keep the tags?
推荐答案
我认为你得到的是正确的数据，但打印出来的错误...您可以尝试使用StreamingMarkupBuilder将节点转换回一片xml吗？
I think you're getting the right data, but printing it out wrong... Can you try using StreamingMarkupBuilder to convert the node back to a piece of xml?
def xml = '''<html>
| <body>
| <textarea><html><body>This has html code for some reason</body></html></textarea>
| </body>
|</html>'''
def ta = new XmlSlurper().parseText( xml ).body.textarea
String content = new groovy.xml.StreamingMarkupBuilder().bind {
mkp.yield ta.children()
}
assert content == '<html><body>This has html code for some reason</body></html>'
