When you are using a parent macro (<se type="parents" />) you will get a problem when it shows more then 3 results.
the second result will get an space. If you check the source you will see this space is actually a breakline.
This is a know issue. There is only one way to solve this issue.
Check example below:
<se type="parents" save="buffername" />
Do not use a macro in xml style and also use replacedata to remove the space from the resultoutput.
