DOM4J parsing XML error: Nested exception:org.xml.sax.SAXParseException:White space is required between the processing instruction Target and data.

Parsing string-type XML in dom4j manner

Xml:string string= "<?xmlversion=\" 1.0\ "encoding=\" utf-8\ "?><root>, Error: Nested exception:org.xml.sax.SAXParseException:White space is required between the processing instruction target an D data.

Later found that the original XML format is incorrect. XMLVersion should be changed to XML version. That is, there should be a space between XML and version.

Switch

string= "<?xml version=\" 1.0\ "encoding=\" utf-8\ "?><root>
