It has not disappeared from enterprise and this has nothing to do with Java. XML is still very good as a document format, with powerful validation capabilities (XSD) and powerful language to do transformation of documents (XSLT), searching documents (XPath). It is still used for a reason.

In addition there are standard ways of encrypting/signing XML documents.

Those aren’t the parts that are used though - it’s the Spring XML as the replacement for the “new” keyword that is more likely to be found than XSLT or XSD.
