How to access contents of OneNote Page? - powershell

Question

I'm new to powershell, and have gotten this far looking for code examples online, however I'm unable to find any examples that show me how to get at the actual page contents of a OneNote page with Powershell.
$OneNote = New-Object -ComObject OneNote.Application
[xml]$Hierarchy = ""
$OneNote.GetHierarchy("",
[Microsoft.Office.InterOp.OneNote.HierarchyScope]::hsPages, [ref]$Hierarchy)
foreach ($notebook in $Hierarchy.Notebooks.Notebook ) {
$notebook.Name
"=============="
foreach ($section in $notebook.Section) {
"# TAB: " + $section.Name
foreach ($page in $section.page) {
" " + $page.Name
#$page.GetAttribute.ToString()
#$page.Attributes
#$page.InnerText
# How do I get to the contents of the page?
}
}
" "
}

Since I was looking for a solution today on how to read OneNote notebook contents using powershell, I was initially pleased that I found this article here. But then I didn't get any further at first because I kept getting an error; namely in the line
Select-Xml -xml($xml.Value) -Namespace $schema -Xpath "//one:Notebook/one:Section" |foreach{
It always said that $xml.Value has the value NULL, and it cannot be cast to the type XmlNode[].
After some trial and error, I found that all I had to do was simply change this line to
Select-Xml -xml $xml -Namespace $schema -Xpath "//one:Notebook/one:Section" |foreach{
so just omit the .Value and the surrounding brackets.
And yes, of course: Thanks to the article creator! I would never have come up with this solution on my own.

You are almost there. Seeing that OneNote content is within an XMLElement. you will need to use Select-Xml to get the information.
Below is an example of how to get the Page property of the XMLElement:
$OneNote = New-Object -ComObject OneNote.Application
$schema = #{one=”http://schemas.microsoft.com/office/onenote/2013/onenote”}
[xml]$Hierarchy = ""
$OneNote.GetHierarchy("",
[Microsoft.Office.InterOp.OneNote.HierarchyScope]::hsPages, [ref]$Hierarchy)
foreach ($notebook in $Hierarchy.Notebooks.Notebook ) {
$notebook.Name
"=============="
foreach ($section in $notebook.Section) {
foreach ($page in $section.page) {
" " + $page
foreach($xml in $page)
{
Select-Xml -xml($xml.Value) -Namespace $schema -Xpath "//one:Notebook/one:Section" |foreach{
$node = $psitem.node
$npath = Split-Path -Path $node.Path -Parent
#This is where all the magic happens
$props = [ordered]#{
Workbook= Split-Path -Path $npath -Leaf
Section = $node.name
Child = $node.ChildNodes
Page = $node.Page #This is your page content
}
New-Object -TypeName PSObject -Property $props
}
}
}
}
}
