    Understanding errors in XML

    in XML

    Posted · Edited by 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!
