ImportNode创建空的xmlns属性 [英] ImportNode creates empty xmlns attribute

问题描述

改编本code：

   var tmpNewNode = xdoc.ImportNode(newNode, true);

    if (oldNode.ParentNode != null)
    {
        oldNode.ParentNode.ReplaceChild(tmpNewNode, oldNode);
        return true;
    }

tmpNewNode是空的xmlns属性（的xmlns =）创建的。任何建议，我怎么能避免呢？

tmpNewNode is created with empty xmlns attribute (xmlns=""). Any suggestion how can I avoid it?

推荐答案

什么是可能发生在这里的是，newNode来自​​一个文件，没有命名空间中声明，但oldNode是与命名空间的文档。在这种情况下，该节点将其空白空间到新文档，并明确地显示出来。说实话，如果它是一个字符串比较只是一个问题，它不会伤害只是从XML字符串中删除的xmlns的所有实例=你使用它。

What's probably happening here is that newNode comes from a document with no namespace declared, but oldNode is in a document with a namespace. In this situation, the node takes its blank namespace over to the new document and it shows up explicitly. To be honest, if it's only a problem for a string comparison, it won't hurt to just remove all instances of xmlns="" from the XML string before you work with it.
