如何解决由于DOCTYPE和DTD限制导致Groovy的XmlSlurper拒绝解析HTML？

我试图复制HTML覆盖率报表中的一个元素，因此覆盖率总计出现在报表顶部以及底部。如何解决由于DOCTYPE和DTD限制导致Groovy的XmlSlurper拒绝解析HTML？

因此，HTML开始，我相信是合式：

<?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" lang="en" xml:lang="en"> 
    <head> 
    <meta http-equiv="Content-Type" content="text/html;charset=UTF-8" /> 
    <link rel="stylesheet" href=".resources/report.css" type="text/css" /> 
    <link rel="shortcut icon" href=".resources/report.gif" type="image/gif" /> 
    <title>Unified coverage</title> 
    <script type="text/javascript" src=".resources/sort.js"></script> 
    </head> 
    <body onload="initialSort(['breadcrumb', 'coveragetable'])">

Groovy的的XmlSlurper抱怨如下：

doc = new XmlSlurper(/* false, false, false */).parse("index.html") 
[Fatal Error] index.html:1:48: DOCTYPE is disallowed when the feature "http://apache.org/xml/features/disallow-doctype-decl" set to true. 
DOCTYPE is disallowed when the feature "http://apache.org/xml/features/disallow-doctype-decl" set to true.

启用DOCTYPE：

doc = new XmlSlurper(false, false, true).parse("index.html") 
[Fatal Error] index.html:1:148: External DTD: Failed to read external DTD 'xhtml1-strict.dtd', because 'http' access is not allowed due to restriction set by the accessExternalDTD property. 
External DTD: Failed to read external DTD 'xhtml1-strict.dtd', because 'http' access is not allowed due to restriction set by the accessExternalDTD property. 

doc = new XmlSlurper(false, true, true).parse("index.html") 
[Fatal Error] index.html:1:148: External DTD: Failed to read external DTD 'xhtml1-strict.dtd', because 'http' access is not allowed due to restriction set by the accessExternalDTD property. 
External DTD: Failed to read external DTD 'xhtml1-strict.dtd', because 'http' access is not allowed due to restriction set by the accessExternalDTD property. 


doc = new XmlSlurper(true, true, true).parse("index.html") 
External DTD: Failed to read external DTD 'xhtml1-strict.dtd', because 'http' access is not allowed due to restriction set by the accessExternalDTD property. 

doc = new XmlSlurper(true, false, true).parse("index.html") 
External DTD: Failed to read external DTD 'xhtml1-strict.dtd', because 'http' access is not allowed due to restriction set by the accessExternalDTD property.

所以我觉得我已经涵盖了所有选项。必须有办法让这个工作，而不诉诸正则表达式和冒着托尼小马的愤怒。

Tsk。

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

即使您的HTML也恰好是格式良好的XML，解析HTML的更通用的解决方案是使用真正的HTML解析器。我过去使用了TagSoup解析器，并且它很好地处理了真实世界的HTML。

TagSoup提供了一个解析器，它实现javax.xml.parsers.SAXParser接口，并且可以在构造函数中提供给XmlSlurper。例如：

@Grab('org.ccil.cowan.tagsoup:tagsoup:1.2.1') 

import org.ccil.cowan.tagsoup.Parser 

def doc = new XmlSlurper(new Parser()).parse("index.html")
