Question

我的xml文件中有以下节点，它是另一个程序的导出。我将不得不在我的应用程序中编辑xml文件，以便我可以正确地导入它。

节点：

<field name="memo" value="24-06-2004 Lorem ipsum dolor "sit" amit"/>

最终它必须变成这样的东西

<field name="memo" value="24-06-2004 Lorem ipsum dolor &quot;sit&quot; amit"/>

或者

<field name="memo" value="24-06-2004 Lorem ipsum dolor 'sit' amit"/>
