Hi Calle,

this is not really a DHIS 2 bug.  The XML spec clearly defines that
special characters such as < and & must be escaped into &amp; and &lt; .
When you export such values from DHIS 2 such characters are properly
escaped.


regards,

Lars

Title:
  XML dxf2 import: Use of ampersand (&) causes crash

Status in DHIS 2:
  Invalid

Bug description:
  When importing a dxf2 (XML) data file that includes one or more
  ampersands in e.g. the comment field, it causes a crash. See the
  tomcat log below - the import process is obviously unable to handle
  the ampersand (code 32) character - and possibly a number of other
  characters too.

  None of this is mentioned in the manuals, though, where the "comment"
  field is only referred to as a "free text" field with no further
  restrictions.

  There are two solutions here: 
  1. The import process is modified to handle "unexpected" characters automatically
  2. A list of "unexpected" characters are published as prohibited (and they should be disallowed within DHIS2 also, then) with a more user-friendly error message when they are encountered.

  Regards
  Calle
