Well, it turns out it's not so simple, and I still need help. Here's
what I have now:
I get the nsIWebPageDescriptor (pageCookie) from the docShell for the
page for which I want to get the source bytes.
I create a new nsIWebBrowser, and initialize it:
mWebBrowser = do_CreateInstance(NS_WEBBROWSER_CONTRACTID);
mWebBrowser->SetContainerWindow(nsnull);
nsCOMPtr<nsIDocShellTreeItem> item =
do_QueryInterface(mWebBrowser);
item->SetItemType(nsIDocShellTreeItem::typeContentWrapper);
I get the nsIBaseWindow and init it:
mBaseWindow = do_QueryInterface(mWebBrowser);
rv = mBaseWindow->InitWindow(ownerAsWidget,
nsnull,
0, 0,
width, height);
I create the baseWindow:
rv = mBaseWindow->Create();
I get the docShell from the webBrowser:
nsCOMPtr<nsIDocShell> newDocShell = do_GetInterface(mWebBrowser);
I get the pageDescriptor from the new docShell:
nsCOMPtr<nsIWebPageDescriptor> newPageDesc =
do_GetInterface(newDocShell);
I load the view source page, using the cookie:
rv = newPageDesc->LoadPage(pageCookie,
nsIWebPageDescriptor::DISPLAY_AS_SOURCE);
I run my event loop to allow the page load to complete:
// allow the page load to complete
nativeBrowserControl->GetWrapperFactory()->ProcessEventLoop();
I get the contentViewer and contentViewerEdit from the docShell:
nsCOMPtr<nsIDocShell> docShell = do_GetInterface(mWebBrowser);
if (!docShell) {
return NS_ERROR_FAILURE;
}
nsCOMPtr<nsIContentViewer> contentViewer;
nsresult rv =
docShell->GetContentViewer(getter_AddRefs(contentViewer));
if (!contentViewer) {
return NS_ERROR_FAILURE;
}
nsCOMPtr<nsIContentViewerEdit>
contentViewerEdit(do_QueryInterface(contentViewer));
I tell it to selectAll();
rv = contentViewerEdit->SelectAll();
NOW here's where I get into trouble. This eventually boils down to
nsHTMLDocument::GetBodyContent(). The problem is that the mBodyContent
ivar never gets set, and I don't know why:
PRBool
nsHTMLDocument::GetBodyContent()
{
if (!mRootContent) {
return PR_FALSE;
}
PRUint32 i, child_count = mRootContent->GetChildCount();
for (i = 0; i < child_count; ++i) {
nsIContent *child = mRootContent->GetChildAt(i);
NS_ENSURE_TRUE(child, NS_ERROR_UNEXPECTED);
if (child->IsContentOfType(nsIContent::eHTML) &&
child->GetNodeInfo()->Equals(nsHTMLAtoms::body,
mDefaultNamespaceID)) {
mBodyContent = do_QueryInterface(child);
return PR_TRUE;
}
}
return PR_FALSE;
I note that a regular render of the page does cause mBodyContent to be
set, but a view Source one does not.
Any ideas?
Ed
