Understanding errors in XML

[stanman109]

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:

1. <?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?>
2. <!DOCTYPE université [ <!ELEMENT université (faculté*,description*)*>
3. <!ELEMENT faculté (département*)> <!ELEMENT département EMPTY>
4. <!ATTLIST département nom CDATA #REQUIRED xmlnote (vide|plein) "plein">
5. <!ATTLIST université téléphone ID #REQUIRED> ]>
6. <université téléphone="514-4321" xml:lang="fr"> <description>La plus grande.</description>
7. <faculté nom="sciences"> <département nom="mathématiques"></département>
8. <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!
