解释由Microsoft Office Word和Excel文档生成的xml

Question

I wish to build a free system to extract the text, text formatting (eg bold etc) and images contents inside documents such as excel and word.

In my research I have found that the structure of excel (xlsx) and word (docx) documents is defined in xml once you extract the document with a compression utility like 7zip.

I am skilled in VBA, however I have not been able to find an object model (listing ALL objects and methods that can be applied /manipulated for any of:

1. Excel VBA
2. Word VBA
3. Word XML
4. Excel XML

I know many excel vba objects already however that is just through trial and error and experimentation, and not through reading an object model where the methods/objects are defined!

The problem

• I don't know how to interpret the XML because I don't have an object model showing me that means bold etc

I am trying to develop a tool which looks through the xml to find:

1. The location of any images in the document, both the relative directory (in the Directory / Word / Media folder) and the actual file path, eg C:\\documents\\josh\\img1.png
2. The position of any text in the document (I'm thinking in terms of lines, reading a document from top to bottom, as well as alignment like centre etc) SO I can reproduce the text in the right order.
3. The formatting applied to the text (bold, some font, some size?

Please help me find an object model or some way to interpret or parse this

Questions about the xml

1. Determining the position of the image (which is at the bottom) relative to the text (which is above it)
2. How many images there are? Is there one because the picture has an ID or INDEX of 0?

Answer 1

Take a look at Office Open XML, that's the xml-structure of all MS-Office documents: http://openxmldeveloper.org/ . There is a rahter good ebook which explains the basics: http://openxmldeveloper.org/blog/b/openxmldeveloper/archive/2007/08/13/1970.aspx

But bewarE: parsing or interpreting Office Open XML is a extremely huge task, especially in VBA which is ill-suited for this job. There are numerous libraries in C# / VB.net which can read office open xml documents, which would be a better starting point.
