Groovy – NekoHTML Sax解析器

以下是我的声明：

def createAndSetParser() { 
  SAXParser parser = new SAXParser()  //Default Sax NekoHTML parser 
  def charset = "Windows-1252"  // The encoding of the page 
  def tagFormat = "upper"    // Ensures all the tags and consistently written,by putting all of them in upper-case. We can choose "lower","upper" of "match" 
  def attrFormat = "lower"  // Same thing for attributes. We can choose "upper","lower" or "match" 

  Purifier purifier = new Purifier()     //Creating a purifier,in order to clean the incoming HTML 
  XMLDocumentFilter[] filter = [purifier] //Creating a filter,and adding the purifier to this filter. (NekoHTML feature) 

  parser.setProperty("http://cyberneko.org/html/properties/filters",filter) 
  parser.setProperty("http://cyberneko.org/html/properties/default-encoding",charset) 
  parser.setProperty("http://cyberneko.org/html/properties/names/elems",tagFormat) 
  parser.setProperty("http://cyberneko.org/html/properties/names/attrs",attrFormat) 
  parser.setFeature("http://cyberneko.org/html/features/scanner/ignore-specified-charset",true)    // Forces the parser to use the charset we provided to him. 
  parser.setFeature("http://cyberneko.org/html/features/override-doctype",false)    // To let the Doctype as it is. 
  parser.setFeature("http://cyberneko.org/html/features/override-namespaces",false)     // To make sure no namespace is added or overridden. 
  parser.setFeature("http://cyberneko.org/html/features/balance-tags",true) 

  return new XmlSlurper(parser)   // A groovy parser that does not download the all tree structure,but rather supply only the information it is asked for. 
}

当我在网站上使用它时,它再次工作得非常好.
有什么猜测为什么我不能在简单的XML文本样本上这样做？

任何帮助大大apreciated
