[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
