七年后，我一直在把头发拉出来。Rod H 的答案是附件，但嵌入图像完全是另一回事。
我最好的运气来自@andre-guirard 的 LotusScript Gold Collection 代码，位于此处：https ://www.openntf.org/main.nsf/project.xsp?r=project/LotusScript%20Gold%20Collection 但是，这并没有一切，因为它不处理嵌入图像以旧方式嵌入的文档。（Notes 改变了它存储嵌入图像的方式。）
我非常努力地将它与此处提供的 AGECOM 信息相结合：https ://www.agecom.com.au/support/agecomkb.nsf/0/58cbf10f0ab723c9ca25803e006c7de8?OpenDocument通过更改 Andre 的 EmbeddedImage 对象以通过查看来无缝处理这两种格式如果富文本字段中的嵌入图像实际上只是指向 $FILE 字段的指针，然后，如果是这样，则获取 FileItem 对象，但最终我用尽了我的理解和选择，以至于我无法证明花费我雇主的钱是合理的资源（我的时间）就可以了。
因此，如果您嵌入的图像都包含在新的方式中，我认为 Andre 的代码将不会受到干扰。否则，我尽了最大努力，但我没有答案......我有什么（对我来说）死胡同，希望你或其他偶然发现它的人可以通过解释我是什么来让我尴尬做错了！
基本上，我从 Andre 的代码开始，并通过以下方式对其进行了更改...
在 DOMUtils 中，添加以下方法：
%REM
Function DU_GetMeOrNextSiblingWithAttr
Description: Starting with a particular node, return that node or the next sibling with an attribute that has a particular value.
Does not recurse into the tree; looks only at the node passed and later siblings.
Parameters:
nodeStart: node to start your search with.
targetElement: element name of desired node.
attrName: attribute name you want to check.
attrValue: attribute value of element you're looking for.
flags: string-matching flags to compare attribute, e.g. 1 for case insensitive.
%END REM
Function DU_GetMeOrNextSiblingWithAttr(nodeStart As NotesDOMNode, ByVal targetElement$, ByVal attrName$, ByVal attrValue$, ByVal flags%) As NotesDOMElementNode
Dim node As NotesDOMNode, elTmp As NotesDOMElementNode
Set node = nodeStart
Do Until node.Isnull
If node.Nodetype = DOMNODETYPE_ELEMENT_NODE Then
If node.Nodename = targetElement Then
Set elTmp = node
If StrComp(elTmp.Getattribute(attrName), attrValue, flags) = 0 Then
Set DU_GetMeOrNextSiblingWithAttr = elTmp
Exit Function
End If
End If
End If
Set node = node.Nextsibling
Loop
End Function
将 FileItem.New 替换为以下代码：
%REM
Sub New
Description: Arguments are the parsed DOM node of the element representing a
design element, and the name of the composite item you would like to read,
modify or create.
%END REM
Sub New(parent As FileItemParent, elNote As NotesDOMElementNode, itemName$, fileName$)
Set m_elNote = elNote
SetItem elNote, itemName$, fileName$
Dim node As NotesDOMNode
Set node = m_elNote.Parentnode
While node.Nodetype <> DOMNODETYPE_DOCUMENT_NODE
Set node = node.Parentnode
Wend
Set m_domd = node
parent.RegisterFileItem Me ' make sure the design element knows about us.
' (in case someone gets smart and invokes the constructor directly
' instead of using the nice methods we've provided).
End Sub
%REM
Sub SetItem
<!-- Created Dec 6, 2017 by JSmart523 -->
If fileName$ is blank, returns the XPath equivalent of elNote/ancestor::document/item[@name=itemName$][position()=1]
If fileName$ is not blank, returns the XPath equivalent of elNote/ancestor::document/item[@name=itemName$][object/file/@name=fileName$][position()=1]
Case insensitive. Changes itemName$ and fileName$ to the correct case if found.
Also sets Me.m_elItem to the returned NotesDOMElementNode
Also sets Me.m_elRawData to the file contents
%END REM
Sub SetItem(elNote As NotesDOMElementNode, itemName$, fileName$)
Dim elFile As NotesDOMElementNode
Dim node As NotesDOMNode
'set node to ancestor::document
Set node = elNote
Do Until node.NodeName = "document"
Set node = node.ParentNode
Loop
'If fileName$ = "", get the first ancestor::document/item[@name=itemName$]
'Otherwise, get the first ancestor::document/item[@name=itemName$][/object/file/@name=fileName$]
Set m_elItem = DU_GetChildOfType(node, DOMNODETYPE_ELEMENT_NODE)
QualifyingItem m_elItem, itemName$, m_elRawData, fileName$
m_itemName = itemName$
m_fileName = fileName$
End Sub
%REM
Sub QualifyingItem
<!-- Created Dec 8, 2017 by JSmart523 -->
Starting with incoming elItem node, ensures it's an item we want or changes elItem to the first sibling that qualifies.
%END REM
Sub QualifyingItem(elItem As NotesDOMElementNode, itemName$, elRawData As NotesDOMElementNode, fileName$)
Dim elFile As NotesDOMElementNode
Dim node As NotesDOMNode
Dim elObject As NotesDOMElementNode
If Not elItem Is Nothing Then
'Initially, elItem is just a starting point, not necessarily the item we want.

Set elItem = DU_GetMeOrNextSiblingWithAttr(elItem, "item", "name", itemName$, 1)
If Not elItem Is Nothing Then
If fileName$ = "" Then
'we have the right item, and aren't looking for a file node, which means we want the rawitemdata node
Set elRawData = DU_getChildNamed("rawitemdata", elItem)
Else
'We are looking for a $FILE item that contains a file.
'There are possibly several $FILE items within a document, one for each file. We've got the right one if ./object/file/@name = fileName$
Do
Set elObject = DU_GetChildNamed("object", elItem)
If Not elObject Is Nothing Then
Set elFile = DU_GetChildWithAttr(elObject, "file", "name", fileName$, 1)
If Not elFile Is Nothing Then
'Yay! We have the right elItem node!
Set elRawData = DU_GetChildNamed("filedata", elFile)
fileName$ = elFile.GetAttribute("name")
Exit Do
End If
End If
Set elItem = DU_GetMeOrNextSiblingWithAttr(elItem.NextSibling, "item", "name", itemName$, 1)
Loop Until elItem Is Nothing
'At this point, either we jumped out of the loop with a valid elItem and elRawData, or elItem is Nothing
End If
End If
End If
If elItem Is Nothing Then
'we didn't find the correct item
'make sure elRawData is changed to Nothing, too.
Set elRawData = Nothing
Else
itemName$ = elItem.GetAttribute("name")
End If
End Sub
同样在 FileItem 脚本库中，添加一个新类 FileItemParent
%REM
Class FileItemParent
<!-- Created Dec 5, 2017 by JSmart523 -->
This is a base class for objects that use FileItem objects
%END REM
Class FileItemParent
m_elElRoot As NotesDOMElementNode
m_elFD As NotesDOMElementNode
Public m_fileItem As FileItem
m_fItems List As FileItem ' list of FileItems we've created and returned to caller.
m_iMode As Integer
%REM
Property Get DOMElement
Description: Return the element node representing the design element.
%END REM
Public Property Get DOMElement As NotesDOMElementNode
Set DOMElement = m_elElRoot
End Property
%REM
Sub New
Arguments:
db: the database containing the design element.
elElement: the DOM element corresponding to the design note (e.g. the <note>
element).
domp: The DOM parser object containing elElement.
%END REM
Sub New(elElement As NotesDOMElementNode)
Set m_elElRoot = elElement
End Sub
Sub Delete
On Error Resume Next
ForAll thing In m_fItems
Delete thing
End ForAll
End Sub
%REM
Function HasItem
Description: Determine whether there's an item element in the note DXL with a
given item name.
Note that the presence of an item doesn't guarantee it's formatted as a file
CD record.
%END REM
Function HasItem(ByVal itemName$) As Boolean
HasItem = Not (DU_GetChildWithAttr(m_elElRoot, "item", "name", itemName, 1) Is Nothing)
End Function
%REM
Function RegisterFileItem
Description: For internal use -- lets the FileItem class notify us that it's
referencing our DOM tree so that we can delete the object if we erase the
corresponding item element.
%END REM
Sub RegisterFileItem(x As FileItem)
Set m_fItems(LCase(x.itemName)) = x
If m_FileItem Is Nothing Then
Set m_FileItem = x
End If
End Sub
%REM
Function GetFileItem
Description: Retrieve the FileItem object associated with a CD-record item.
An object will be returned even if the item doesn't exist, which you can
use to create the item via UpdateFile method.
%END REM
Function GetFileItem(itemName$, fileName$) As FileItem
Set GetFileItem = New FileItem(Me, m_elElRoot, itemName, fileName)
End Function
End Class
FileItemParent 类主要是取自 Andre 的 FileResource 类的代码，以便 FileResource 和 EmbeddedImage 都可以使用它。更改 FileResource 以扩展 FileItemParent，删除所有重复的代码。
现在我们要更改 EmbeddedImage，以便即使嵌入的图像节点包含指向 $FILE 项的链接而不是实际内容，也返回实际内容。
因此，更改 EmbeddedImage 以扩展 FileItemParent
将以下方法添加/替换到 EmbededImage
%REM
Sub InitFileItem
<!-- Created Dec 6, 2017 by JSmart523 -->
Called by New
%END REM
Sub InitFileItem()
Dim buffer As Variant 'byte array
Dim iFileNameLen As Integer
Dim sFileName As String
Dim sItemName As String
Dim stream As NotesStream
If Len(m_b64) < 30000 Then
'If content is short then maybe it's a link to a $FILE item instead of the actual content?
Dim session As New NotesSession
Set stream = session.CreateStream()
Base64ToBinary m_b64, stream
stream.Position = 0
buffer = stream.Read(1)
If buffer(0) = 196 Then
'this is a link to a $FILE, not the actual image contents!
stream.Position = 10
buffer = stream.Read(2)
iFileNameLen = ConvertWordByteArray(buffer)
stream.Position = 24
buffer = stream.Read(iFileNameLen)
sFileName = BytesToString(buffer)
sItemName = "$FILE"
GetFileItem sItemName, sFileName 'sets m_fileItem to a FileItem object
End If
End If
End Sub
%REM
Property Get SuggestedFileName
%END REM
Public Property Get SuggestedFileName As String
If m_fileItem Is Nothing Then
SuggestedFileName = "Embedded-" + ItemName + "." + SuggestedFileType
Else
SuggestedFileName = m_fileItem.FileName
If InStr(SuggestedFileName, ".") = 0 Then
SuggestedFileName = SuggestedFileName + "." + SuggestedFileType
End If
End If
End Property
%REM
Property Get SuggestedFileType
%END REM
Public Property Get SuggestedFileType As String
If ImageType = "notesbitmap" Then
SuggestedFileType = "bmp"
Else
SuggestedFileType = ImageType
End If
End Property
%REM
Sub ReadFileToStream
%END REM
Sub ReadFileToStream(streamOut As NotesStream)
If m_FileItem Is Nothing Then
ReadToStream streamOut
Else
Set m_FileItem.Stream = streamOut
m_FileItem.Load
End If
End Sub
然后将 EmbeddedItem.New 更改为最后调用 InitFileItem ，这样如果它是一个链接，那么获取内容将返回内容而不是链接。
好的，据我所知，到目前为止一切都很好，但问题是存储在 $FILE 项目中的嵌入图像的 CD 记录（即富文本字段的嵌入图像节点仅包含一个链接而不是实际图像）已记录在案尽管有 AGECOM 的代码和解释，但对我来说，这种方式是难以理解的。我可以使用上面的代码和 Andre 的 EmbeddedImageList 对象来抓取每个嵌入的图像，但我根本无法让“ConvertOldCDToNew”方法正常工作，所以我无法将旧的 CD 记录格式转换为可靠的、未损坏的文件！我不知道我是否剥离了太多字节，没有剥离正确的字节，或者我只是忘了携带两个！
