Question

您好在我的代码中运行以下行，但此代码在执行期间崩溃。

ByteArrayInputStream input = new ByteArrayInputStream(fileContent);

final HtmlCleaner cleaner = new HtmlCleaner();
CleanerProperties props = cleaner.getProperties();

DomSerializer doms = new DomSerializer(props, true);

org.w3c.dom.Document xmlDoc = null;

try {
    TagNode node = cleaner.clean(input);
    xmlDoc = doms.createDOM(node);
} catch (Exception e) {
    System.out.println("Tiding error ");
    e.printStackTrace();
}

这是错误的堆栈跟踪：

NAMESPACE_ERR: An attempt is made to create or change an object in a way which is incorrect with regard to namespaces.
    at com.sun.org.apache.xerces.internal.dom.CoreDocumentImpl.checkDOMNSErr(CoreDocumentImpl.java:2535)

    at org.htmlcleaner.DomSerializer.setAttributes(DomSerializer.java:97)
    at org.htmlcleaner.DomSerializer.createDOM(DomSerializer.java:37)

任何人都可以帮忙找出原因吗？

此致，Zoli

HTMLCleaner遇到了处理命名空间的问题。下面是一个XML命名空间声明示例，它会给它带来麻烦：

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="de" lang="de"
  xmlns:og="http://ogp.me/ns#" xmlns:fb="http://www.facebook.com/2008/fbml" 
  itemscope itemtype="http://schema.org/CreativeWork">

您可以看到itemscope属性已损坏，因此HtmlCleaner会抛出NAME_SPACE_ERR。

避免此问题的一种方法是添加行

props.setNamespacesAware(false);

关闭命名空间处理。
