Assume the following source structure:

1. <div>
2. aaa
3. <br>
4. bbb
5. <b>mytitle1234</b>
6. ccc
7. <br>
8. <h3> h3headline</h3>
9. ddd
10. <br>
11. eee
12. <br>
13. </div>
14. lineoutside

Now I want (simplified) to change the font size of all text which follows "<b>mytitle1234</b>" but only on the same hierarchy level.

If I code

1. $("b:contains('mytitle1234')").nextAll()......

then the fontsize of only the <h3> element will be changed.

But I want to change "ccc" "ddd" "eee" as well (but not "lineoutside").

How can I achieve this?
