Unicode(0xb) error while parsing an XML file using Stax

Question

While parsing an XML file Stax produces an error:

Unicode(0xb) error-An invalid XML character (Unicode: 0xb) was found in the element content of the document.

Just click on the link below with the xml line with special character as "VI". It's not an alphabetical character: when you try to copy and paste it in Notepad, you will get it as some symbol. I have tried parsing it using Stax. It was showing the above-mentioned error.

Please can somebody give me a solution for this?

Thanks in advance.

Answer 1

0xB (vertical tab) is not a valid character in XML. The only valid characters before ASCII 32 (0x20, space) are 0x9 (tab), 0xA (carriage return) and 0xD (line feed).

In short, what you are trying to parse is NOT XML.

Answer 2

Whenever invalid xml character comes xml, it gives such error. When u open it in notepad++ it look like VT, SOH,FF like these are invalid xml chars. I m using xml version 1.0 and i validate text data before entering it in database by pattern

Pattern p = Pattern.compile("[^\u0009\u000A\u000D\u0020-\uD7FF\uE000-\uFFFD\u10000-\u10FFF]+");
retunContent = p.matcher(retunContent).replaceAll("");

It will ensure that no invalid special char will enter in xml
