[OS] OSrL problem

[Mike Steglich]

Hi,

If I try to solve an integer problem with Clp < OSSolverService -osil problemname.osil -solver clp> then I get the following OSrL file that seems not well-formed. 
Therefore it is difficult to catch automatically (e.g. by using Qt's  QDomDocument, QDomElement, QDomNode)  the message that is written in the OSrL file.

<?xml version="1.0" encoding="UTF-8"?><?xml-stylesheet type="text/xsl" href="http://www.coin-or.org/OS/stylesheets/OSrL.xslt"?>
<osrl xmlns="os.optimizationservices.org"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="os.optimizationservices.org http://www.optimizationservices.org/schemas/2.0/OSrL.xsd" >
<general>
<generalStatus type="error">

<message><?xml version="1.0" encoding="UTF-8"?><?xml-stylesheet type="text/xsl" href="http://www.coin-or.org/OS/stylesheets/OSrL.xslt"?>

<generalStatus type="error">

<message>Clp cannot do integer programming</message>

Cheers,
