c# - XMLException when processing RSS -

-

i've been trying process rss feeds using argotic newsreader application. of them works fine, on feed (like this) breaks following:

additional information: security reasons dtd prohibited in xml document. enable dtd processing set dtdprocessing property on xmlreadersettings parse , pass settings xmlreader.create method.

the error straightforward, passed xmlreadersettings object dtdprocessing enabled. following appeared:

an unhandled exception of type 'system.xml.xmlexception' occurred in system.xml.dll additional information: ';' character, hexadecimal value 0x3b, cannot included in name. line 9, position 366.

the code using:

    xmlreadersettings settings = new xmlreadersettings();     settings.ignorecomments = true;     settings.ignorewhitespace = true;     settings.dtdprocessing = dtdprocessing.parse;      xmlreader reader = xmlreader.create(this.url, settings);     rssfeed feed = new rssfeed();     feed.load(reader);

what missing?

the exception telling rss feed illegal - specifically, name contains ; character. w3c specification appears prohibit this:

document authors encouraged use names meaningful words or combinations of words in natural languages, , avoid symbolic or white space characters in names. note colon, hyphen-minus, full stop (period), low line (underscore), , middle dot explicitly permitted.

the ascii symbols , punctuation marks, along large group of unicode symbol characters, excluded names

since other rss readers complained feed invalid. @ time of writing however, w3c validator shows valid!

according msdn documentation xmlreadersettings.conformancelevel, issue cause exception whatever conformancelevel, might find setting in xmlreadersettings can turn behaviour off (supply settings xmlreader.create). otherwise, if feed can't fixed, you'll have perform pre-processing on it.
