[Quickfix-developers] toXML function for 'special XML characters'

[Van G. E. (K. 2) <edd...@cr...>]

Hi Oren,

after receiving a message in the Fixengine I use the toXML function to obtain the XML version of the message and then perform XSLT to transform to our internal format.

for some special XML characters I had to add a bit of code in the Message.cpp to transform 

& in &
< in &lt;
" in &quot;

otherwise the generated XML is not OK.

<field name="Text" number="58" value="PRICE < 100"/> 

should be  

<field name="Text" number="58" value="PRICE &lt; 100"/>


is this somthing that you would want to put in the base quickfix release ?

Rgds,
Eddy



std::string Message::toXMLFields(const FieldMap& fields, int space) const
{ QF_STACK_PUSH(Message::toXMLFields)

  std::stringstream stream;
  FieldMap::iterator i;
  std::string name;
  for(i = fields.begin(); i != fields.end(); ++i)
  {
    int field = i->first;
    std::string value = i->second.getString();

*********************
    size_t lookHere = 0;
    size_t foundHere;
    while ((foundHere = value.find("&",lookHere))
    != std::string::npos) {
    value.replace(foundHere, 1, "&amp;");
     lookHere = foundHere + 5;
    }
    lookHere = 0;
    while ((foundHere = value.find("<",lookHere))
    != std::string::npos) {
    value.replace(foundHere, 1, "&lt;");
    lookHere = foundHere + 4;
    }
    lookHere = 0;
    while ((foundHere = value.find('"',lookHere))
    != std::string::npos) {
    value.replace(foundHere, 1, "&quot;");
    lookHere = foundHere + 6;
    }

Hmm.  Yeah we should be handling this.  Although I wonder if maybe we 
should just be putting the values into a CDATA section?
