如何知道DOMDocument是否由解析器拥有 [英] How to know if a DOMDocument is owned by a parser

问题描述

我正在调查一个API从两个不同的来源调用的问题。
我们有一个叫dispatch的API。其签名如下。

  DOMDocument * dispatch（DOMDocument * requestDocument）
  / pre> 
 
 
我们观察到这个API可以通过传递一个DOMDocument对象来调用
 
 
 
使用DOMImplementation :: createDocument创建的独立DOMDocument对象
  http://xerces.apache.org/xerces-c/apiDocs-3/classDOMImplementation.html  
 
 
 
 
 A parse own DOMDocument object created using AbstractDOMParser :: getDocument 
  http ：//xerces.apache.org/xerces-c/apiDocs-3/classAbstractDOMParser.html#143bc9285686b49f0f06a184b079292a  
 
 
 
如果我使用方法1创建了一个文档，它不会被解析器拥有。但是，如果我使用方法2创建它，它将由解析器拥有。 
 
 
 
我的问题是，如果我有一个文档，我怎么知道它是否由解析器拥有？。
 
 
 
你能帮我上这个或指点我一些资源。

它们都是解析的结果。
 
I am looking into an issue where an API is getting called from two different sources.
We have an API called dispatch. Its signature is as follows.
DOMDocument* dispatch( DOMDocument * requestDocument )
We observed that this API can be called by passing a DOMDocument object that is 

A stand-alone DOMDocument object created using DOMImplementation::createDocument
http://xerces.apache.org/xerces-c/apiDocs-3/classDOMImplementation.html
A parse owned DOMDocument object created using AbstractDOMParser::getDocument
http://xerces.apache.org/xerces-c/apiDocs-3/classAbstractDOMParser.html#143bc9285686b49f0f06a184b079292a
If i created a document using approach 1, it wont be owned by the parser. However, if i create it using approach 2, it would be owned by the parser. 

My question is, if i have a document, how would i know whether it is owned by a parser or not?.

Can you please help me on this or point me to some resource. I am exploring as we speak.

Thanks,
PAvan.
解决方案
They're both the result of parsing.
