Summary20345: LSS files with text labels containing "<" are not imported correctly and result in empty items
Description

At our survey a subquestion had this text:
<Ressources pour l’enseignement et

Exporting to LSS and importing at another system lead to an empty element at this question for this label. Probably the "<" character was not escaped properly and lead to a broken XML structure.

Steps To Reproduce

Steps to reproduce

Import the attached LSS file.
Open the French (FR) logic file.
Search for question "5-06. Les éléments d’information suivants" and check subquestions

Expected result

See all subquestions.

Actual result

SQ003 is empty though the LSS contains the correct label.

TagsNo tags attached.

The XML structure is fine. The text is not saved properly in the LSS, probably because it was not properly saved in the original survey.
The character < needs to be quoted in HTML to work properly.
On import this looks like invalid HTML which is then removed most likely by the XSS fiter.
