Can we search or filter " data-tag='to-do' " in onenote API ? If yes then how we can do this? - onenote

Question

How can we use OneNote tags (like data-tag='to-do') with search or filter in OneNote API. I tried using provide operators but found no success.
I tried in this way --
$url = "https://www.onenote.com/api/v1.0/me/notes";
//$url .= "/pages?search=hello";
$url .= "/pages?filter=data-tag eq 'to-do'";
I want to search data-tag and then extract the data from OneNote pages which contains the data-tag='to-do'.
Any help is appreciated and thanks in advance.

Answer 1

You'll have to run through all your pages.
For each pages, you can retrieve its content with a GET call to https://www.onenote.com/api/v1.0/me/notes/pages/%s/content?includeIds=true
From there you get a string that you can parse.
I'll advise you to use jsoup.
With jsoup you can then write (assuming contentcontains your page's content):
Document doc = Jsoup.parse(content);
Elements todos=doc.select("[data-tag^=\"to-do\"]");
for(Element todo:todos) {
System.out.println(todo.ownText());
}

Sadly OneNote API doesn't support it yet, so I've written my custom parser which extracts notes with data-tags from page content. Here it is:
public class OneNoteParser
{
static public List<Note> ExtractTaggedNotes(string pageContent, string tag = "*")
{
List<Note> allNotes = new List<Note>();
string[] dataTagString = { "data-tag=\""};
string[] dirtyNotes = pageContent.Split(dataTagString, StringSplitOptions.RemoveEmptyEntries);
//First one in this array can be dropped as it doesn't contain todo
for (int i = 1; i < dirtyNotes.Length; i )
{
string curStr = dirtyNotes[i];
Note curNote = new Note();
// Firstly we need to extract all the tags from it (sample html: data-tag="to-do:completed,important" ....)
string allTags = curStr.Substring(0,curStr.IndexOf("\""));
curNote.Tags = new List<string>(allTags.Split(','));
// Now we have to jump to the next ">" symbol and start finding the text after it
curStr = curStr.Substring(curStr.IndexOf(">"));
int depth = 1;
bool addAllowed = false;
for (int j = 0; j < curStr.Length - 1; j )
{
// Finding next tag opener "<" symbol
if (curStr[j] == '<')
{
addAllowed = false;
// Checking if it is not "</" closer
if (curStr[j 1] == '/')
{
// Means this is a tag closer. Decreasing depth
depth--;
}
else
{
// Means this is an tag opener. Increasing depth
depth ;
}
}
else if (curStr[j] == '>')
{
addAllowed = true;
if (j > 0 && curStr[j - 1] == '/')
{
// Means this is a tag closer. Decreasing depth
depth--;
}
}
else
{
if (depth < 1)
{
// Found end of the tag. Saving index and exiting for loop
break;
}
if (addAllowed)
curNote.Text = curStr[j]; // Appending letter to string
}
}
// Filtering by tag and adding to final list
if (tag == "*" || curNote.Tags.Any(str => str.Contains(tag)))//curNote.Tags.Contains(tag, StringComparer.CurrentCultureIgnoreCase))
allNotes.Add(curNote);
}
return allNotes;
}
}
And here is the class Note
public class Note
{
public string Text;
public List<string> Tags;
public Note()
{
Tags = new List<string>();
}
}
To extract todo-s simply call this function:
OneNoteParser.ExtractTaggedNotes(pageContent, "to-do");
Also you can extract other tags like this:
OneNoteParser.ExtractTaggedNotes(pageContent, "important");
OneNoteParser.ExtractTaggedNotes(pageContent, "highlight");
