Convert WPF Flowdocument to Plain Text

Question

We have an application in WPF that stores flowdocuments in a SQL DB that users can modify and send to each other within the system.

My main problem is searching on the flowdocument within the Text column as full text searching matches the flowdocument xaml tags as well. Is there a way to convert a flowdocument to plain text for searching or tell SQL full text searcher how to search flowdocuments?

Hi there,

not that I know of (which doesn't necessarily mean there is none). Just an idea - what you might be able to do is to store both the formatted and the unformatted text in separate columns of your DB-table (storage is cheap these days). In order to get all the text, you could use something like (untested):

public static string FlowDocument_GetText(FlowDocument fd)
{
	TextRange tr = new TextRange(fd.ContentStart, fd.ContentEnd);
	return tr.Text;
}

Thanks Olaf

I will give this a try, as long as it returns only the text and no xaml, I am happy to store it as well.
