Parser just holds on syntax error

[ssenesi]

When reading an xml construct such as

<field field_ref="albs" default_value="1.e+20"/>/>

which shows a syntax error near to the end of line, Xios parser just holds

If the xml file is quite long, you may spend some tens of minutes searching for the error (assuming you suspect it is a syntax error, and you are not beginning your search elsewhere ....)

I can confirm this issue. It looks like a bug in the XML parser we use, namely RapidXML. Unfortunately development seems to have stalled, there has not been any new versions since 2013.

The XML file doesn't have the good structure, so the internal XML parser (rapidXML) is lost.
We don't want to modify RapidXML, which is considered as an external tool. At short time we don't plan to replace it with a other (and best) parser.
