推荐答案

通过OneNote中的OCR识别文本存储在之一：OCRText 在OneNote中的XML文件的结构元素。 。例如

Text recognized by OneNote's OCR is stored in the one:OCRText element in the XML file structure in OneNote. e.g.

<one:Page ...>
    ...
    <one:Image ...>
        ...
        <one:OCRData lang="en-US">
            <one:OCRText><![CDATA[This is some sampletext]]></one:OCRText>
        </one:OCRData>
    </one:Image>
</one:Page>

您可以看到使用了一个名为OMSPY程序（它表明你的OneNote页面背后的XML）这个XML - 的http：/ /blogs.msdn.com/b/johnguin/archive/2011/07/28/onenote-spy-omspy-for-onenote-2010.aspx

You can see this XML using a program called OMSPY (it shows you the XML behind OneNote pages) - http://blogs.msdn.com/b/johnguin/archive/2011/07/28/onenote-spy-omspy-for-onenote-2010.aspx

要提取您需要使用的OneNote COM互操作的文本（正如你所指出）。 。例如

To extract the text you would use the OneNote COM interop (as you pointed out). e.g.

//Instantialize OneNote
ApplicationClass onApp = new ApplicationClass();

//Get the XMl from the selected page
string xml = "";
onApp.GetPageContent("put the page id here", out xml);

//Put it into an XML document (from System.XML.Linq)
XDocument xDoc = XDocument.Parse(xml);

//OneNote's Namespace - for OneNote 2010
XNamespace one = "http://schemas.microsoft.com/office/onenote/2010/onenote";

//Get all the OCRText from the page
string[] OCRText = xDoc.Descendants(one + "OCRText").Select(x => x.Value).ToArray();
