如何使用IAccessible在Firefox中访问文档的HTML

问题描述

  Guid guid = new Guid（{618736E0 -3C3D-11CF-810C-00AA00389B71}）; 
 object obj = null; 
 int ret = AccessibleObjectFromWindow（hWnd，
（uint）OBJID.WINDOW，ref guid，ref obj）; 
 Accessibility.IAccessible acc =（Accessibility.IAccessible）obj; 
  

但是，我不知道该从哪里出发。我需要从文档中获取完整的HTML。我知道IAccessible.get_accValue（）方法，但我不太确定如何使用它与Firefox相关。任何帮助，将不胜感激。显然你不能使用IAccessible获得完整的HTML源代码。我发现这一点，但它不能在FF3.5：

  IServiceProvider * pServProv = NULL; 
 pAccessible-> QueryInterface（IID_IServiceProvider，（void **）& pServProv）; 
 ISimpleDOMNode * pSimpleDOMNode; 
 if（pServProv）{
 const GUID refguid = {0x0c539790，0x12e4，0x11cf，0xb6，0x61，
 0x00，0xaa，0x00，0x4c，0xd6，0xd8}; 
 HRESULT result = pServProv-> QueryService（refguid，IID_ISimpleDOMNode，
（void **）& pSimpleDOMNode）; 
 if（SUCCEEDED（hresult）&& pSimpleDOMNode！= NULL）{
 / *这是一个Mozilla节点！使用
 ISimpleDOMNode.idl中描述的特殊的ISimpleDOMNode方法。 * / 
} 
} 
  

我也发现这个在FF3.5中工作：

pre $ $ $ c $ HRESULT hr = AccessibleObjectFromWindow（hwnd，OBJID_CLIENT，
IID_IAccessible，（void ** ）及pAccessible）;
if（SUCCEEDED（hr）&& pAccessible！= NULL）{
HRESULT hr = pAccessible-> QueryInterface（
IID_ISimpleDOMNode，（void **）& pSimpleDOMNode）;
}

我卡住了。 ：（

I can get an IAccessible object from a Firefox window using this code:

Guid guid = new Guid("{618736E0-3C3D-11CF-810C-00AA00389B71}");
object obj = null;
int ret = AccessibleObjectFromWindow(hWnd,
    (uint) OBJID.WINDOW, ref guid, ref obj);
Accessibility.IAccessible acc = (Accessibility.IAccessible)obj;

However, I'm not sure where to go from here. I need to get the full HTML from the document. I know about the IAccessible.get_accValue() method, but I'm not really sure how to use it in relation to Firefox. Any help would be much appreciated.

解决方案

Apparently you can't get the full HTML source using IAccessible. I found this but it doesn't work in FF3.5:

IServiceProvider *pServProv = NULL;
pAccessible->QueryInterface(IID_IServiceProvider, (void**)&pServProv);
ISimpleDOMNode *pSimpleDOMNode;
if (pServProv) {
  const GUID refguid = {0x0c539790, 0x12e4, 0x11cf, 0xb6, 0x61,
                        0x00, 0xaa, 0x00, 0x4c, 0xd6, 0xd8};
  HRESULT result = pServProv->QueryService(refguid, IID_ISimpleDOMNode,
                                           (void**)&pSimpleDOMNode);
  if (SUCCEEDED(hresult) && pSimpleDOMNode != NULL) {
    /* This is a Mozilla node! Use special ISimpleDOMNode methods described in
      ISimpleDOMNode.idl. */
  }
}

I also found this, which doesn't work in FF3.5 either:

HRESULT hr = AccessibleObjectFromWindow(hwnd, OBJID_CLIENT,
      IID_IAccessible, (void**)&pAccessible);
if (SUCCEEDED(hr) && pAccessible != NULL) {
HRESULT hr = pAccessible->QueryInterface(
      IID_ISimpleDOMNode, (void**)&pSimpleDOMNode);
}

I'm stuck. :(
