how to extract text by style in openoffice

I have an openoffice text using different styles. I need to extract all text in one style as a text .txt file (but not including text marked in the other styles). How can this be achieved?

I tried to mark other styles as hidden and save as .txt, but the result contains all text, not only the one which is visible. If I save as .pdf and then cut and paste the text from I get what I need, but this seems a roundabout solution and I am certain a better one exists.

To select all text with a certain paragraph style, go to Edit -> Find & Replace. Expand Other options and check Paragraph Styles. Then select the style name to Find and press Find All.

Now close the dialog. Copy and paste to a text editor such as Notepad (depending on your operating system). Then save the text file from the text editor.

For character styles, this will not work, so use AltSearch.
