Hello,

It's possible to remove an xmlElement in the onePage by api?

I try out the following things.

1. GetContent with oneNoteApp.GetPageContent(...)
Result:

<?xml version="1.0"?>
<one:Page xmlns:one="http://schemas.microsoft.com/office/onenote/2010/onenote" ID="{67AE1C64-ACA7-4DF6-9CBE-EE0F4C37C2CB}{1}{E19560793461111514907320169340014166064608271}" name="Seite ohne Titel" dateTime="2020-06-05T08:01:45.000Z" lastModifiedTime="2020-06-05T08:53:44.000Z" pageLevel="1" selected="partial" lang="de">
  <one:QuickStyleDef index="0" name="PageTitle" fontColor="automatic" highlightColor="automatic" font="Calibri Light" fontSize="20.0" spaceBefore="0.0" spaceAfter="0.0" />
  <one:QuickStyleDef index="1" name="p" fontColor="automatic" highlightColor="automatic" font="Calibri" fontSize="11.0" spaceBefore="0.0" spaceAfter="0.0" />
  <one:PageSettings RTL="false" color="automatic">
    <one:PageSize>
      <one:Automatic />
    </one:PageSize>
    <one:RuleLines visible="false" />
  </one:PageSettings>
  <one:Title selected="partial" lang="de">
    <one:OE author="" authorInitials="MT" lastModifiedBy="" lastModifiedByInitials="MT" creationTime="2020-06-05T08:14:24.000Z" lastModifiedTime="2020-06-05T08:14:24.000Z" objectID="{24B28869-2118-4D0C-A3AE-5CD72DE95CE5}{15}{B0}" alignment="left" quickStyleIndex="0" selected="partial">
      <one:T selected="all"><![CDATA[]]></one:T>
    </one:OE>
  </one:Title>
  <one:Outline author="" authorInitials="MT" lastModifiedBy="" lastModifiedByInitials="MT" lastModifiedTime="2020-06-05T08:15:55.000Z" objectID="{28C8BE49-4F84-414D-A20D-6EB99E8728AE}{63}{B0}">
    <one:Position x="36.0" y="86.4000015258789" z="0" />
    <one:Size width="72.0" height="13.42771339416504" />
    <one:OEChildren>
      <one:OE creationTime="2020-06-05T08:15:55.000Z" lastModifiedTime="2020-06-05T08:15:55.000Z" objectID="{28C8BE49-4F84-414D-A20D-6EB99E8728AE}{64}{B0}" alignment="left" quickStyleIndex="1">
        <one:T><![CDATA[]]></one:T>
      </one:OE>
    </one:OEChildren>
  </one:Outline>
</one:Page>


2. Now I remove outline element

<?xml version="1.0"?>
<one:Page xmlns:one="http://schemas.microsoft.com/office/onenote/2010/onenote" ID="{67AE1C64-ACA7-4DF6-9CBE-EE0F4C37C2CB}{1}{E19560793461111514907320169340014166064608271}" name="Seite ohne Titel" dateTime="2020-06-05T08:01:45.000Z" lastModifiedTime="2020-06-05T08:53:44.000Z" pageLevel="1" selected="partial" lang="de">
  <one:QuickStyleDef index="0" name="PageTitle" fontColor="automatic" highlightColor="automatic" font="Calibri Light" fontSize="20.0" spaceBefore="0.0" spaceAfter="0.0" />
  <one:QuickStyleDef index="1" name="p" fontColor="automatic" highlightColor="automatic" font="Calibri" fontSize="11.0" spaceBefore="0.0" spaceAfter="0.0" />
  <one:PageSettings RTL="false" color="automatic">
    <one:PageSize>
      <one:Automatic />
    </one:PageSize>
    <one:RuleLines visible="false" />
  </one:PageSettings>
  <one:Title selected="partial" lang="de">
    <one:OE author="" authorInitials="MT" lastModifiedBy="l" lastModifiedByInitials="MT" creationTime="2020-06-05T08:14:24.000Z" lastModifiedTime="2020-06-05T08:14:24.000Z" objectID="{24B28869-2118-4D0C-A3AE-5CD72DE95CE5}{15}{B0}" alignment="left" quickStyleIndex="0" selected="partial">
      <one:T selected="all"><![CDATA[]]></one:T>
    </one:OE>
  </one:Title>
</one:Page>




3. Update page content with method: oneNoteApp.UpdatePageContent(...)

4. Result is the like after step 1.

What I'm doing wrong to remove an element from the OneNote page?

Thanks for your help.

Best regards,
Mitch

Hello Mitch,

This should work. You can send me your project and test notebook(s) to the support email address; find it in {Add-in Express installation folder}\readme.txt; please make sure your email contains a link to this topic.

Hello Mitch,

Alas, that was my fault. The description of the UpdatePageContent method at https://docs.microsoft.com/en-us/office/client-developer/onenote/application-interface-onenote#page-content-methods contains this paragraph:

The only objects that you must include in the XML code that you pass to the UpdatePageContent method are page-level objects (such as outlines, images on the page, or ink on the page) that have changed. This method does not modify or remove page-level objects that you do not specify in the bstrPageChangesXmlIn parameter. The method entirely replaces page-level objects, such as outlines, whose IDs match those of the objects you pass. Consequently, you must fully specify all page-level objects in your code, including their existing content and changes you want to make to them.


The method deleting an object is DeletePageContent; see the same page. It requires that you specify the page Id and the object id.

I'm sorry.

The code below works for me.

After my first test, starting OneNote produced a OneNote message sort of "we are recovering". I suppose - and it would be natural to expect this - that OneNote requires releasing COM objects. Whence the ReleaseComObject calls in my code.

OneNote.Windows windows = OneNoteApp.Windows;
OneNote.Window window = windows.CurrentWindow;
string pageId = window.CurrentPageId;
Marshal.ReleaseComObject(window); window = null;
Marshal.ReleaseComObject(windows); windows = null;

OneNoteApp.GetPageContent(pageId,out string pageContent);

XDocument doc = XDocument.Parse(pageContent);
XElement page = doc.Root;
XNamespace oneNoteNamespace = page.Name.Namespace;            
XElement firstOutline = page.Descendants(oneNoteNamespace+  "Outline").FirstOrDefault();
string outlineId = firstOutline.Attribute("objectID").Value;

OneNoteApp.DeletePageContent(pageId, outlineId);
