When I use the jstl tag to read the XML file, I always get the error "Content is not allowed in the preface". After checking, the XML file format and content are correct. After searching on Baidu, I found out that it was a file encoding problem.
Use Notepad to open the xml file and convert it to UTF-8. There will be a BOM header, so java will report the above error when reading.
Solution: Open it with notepad++, select "Encode in UTF-8 BOM-free format" in the format, and then save it. You can also use EmEditor to save as a file, and select "UTF-8 No Signature" when saving.
