Hi everyone, I'm a beginner in XML and I'm still learning the basics. I need to find how many errors are in the following XML document: <?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?> <!DOCTYPE université [ <!ELEMENT université (faculté*,description*)*> <!ELEMENT faculté (département*)> <!ELEMENT département EMPTY> <!ATTLIST département nom CDATA #REQUIRED xmlnote (vide|plein) "plein"> <!ATTLIST université téléphone ID #REQUIRED> ]> <université téléphone="514-4321" xml:lang="fr"> <description>La plus grande.</description> <faculté nom="sciences"> <département nom="mathématiques"></département> <département nom="sociologie" xmlnote="vide"/> </faculté> </université> Eclipse flagged the following errors: Attribute "nom" must be declared for element type "faculté". (line 7)Attribute "xml:lang" must be declared for element type "université". (line 6) Attribute value "514-4321" of type ID must be a name. (line 6) Could someone kindly explain those errors and what I did wrong? Is it possible that more errors than the ones Eclipse flagged are in the file? What validation tools do you guys use? Thank you very much in advance!
