#9870: boost::property_tree::write_xml_element does not encode character before
writing to attribute value
-------------------------------------+---------------------------
 Reporter:  Alex K Yau <alex.yau@…>  |      Owner:  cornedbee
     Type:  Bugs                     |     Status:  new
Milestone:  To Be Determined         |  Component:  property_tree
  Version:  Boost 1.55.0             |   Severity:  Problem
 Keywords:                           |
-------------------------------------+---------------------------
 The character in attribute value is not encoded in entity names and may
 output a quote " to attribute value which escapes the attribute value and
 thus outputs a wrong value.

 if the attribute stored in attribs is ("mystring", "\"") under node x.
 The expected output string is <x mystring="&quot;"/> instead of <x
 mystring="""/>. The value is &quot;, but not null string and the quote in
 the tag should be balanced.

 This can resolve by changing
 "boost/property_tree/detail/xml_parser_write.hpp" Line 118 to 119
 from

 {{{
 stream << Ch(' ') << it->first << Ch('=') <<
           Ch('"') << it->second.template get_value<std::basic_string<Ch>
 >() << Ch('"');
 }}}


 to

 {{{
 stream << Ch(' ') << it->first << Ch('=') <<
           Ch('"') << encode_char_entities(it->second.template
 get_value<std::basic_string<Ch> >()) << Ch('"');
 }}}
