Java XML Problem: The markup in the document following the root element must be well-formed

Question

I'm receiving this error: [Fatal Error] Adverts.xml:26:2: The markup in the document following the root element must be well-formed. org.xml.sax.SAXParseException; systemId: file:/C:/Users/NULL/Desktop/Adverts.xml; lineNumber: 26; columnNumber: 2; The markup in the document following the root element must be well-formed. [Fatal Error] Adverts.xml:26:2: The markup in the document following the root element must be well-formed. org.xml.sax.SAXParseException; systemId: file:/C:/Users/NULL/Desktop/Adverts.xml; lineNumber: 26; columnNumber: 2; The markup in the document following the root element must be well-formed.

I have google researched it and tried too figure what I may be possibly doing wrong. However I have no idea. The XML file goes as such:

    <advertisement>
    <server name="Zenith"> 
    <discordlink>http://zenithps.org</discordlink>
    <ownerid>304558905306906624</ownerid>

    <image>C:/Users/NULL/Pictures/Upgrade.gif</image>
    <image>C:/Users/NULL/Pictures/Pet.png</image>
    </server>

    <guild id="642406906580828181">

    <user>304558905306906624</user>
    <delay>25000</delay>
    </guild>

    </advertisement>


    <advertisement>
    <server name="Test Server"> 
    <discordlink>http://zenithps.org</discordlink>
    <ownerid>304558905306906624</ownerid>

    <image>C:/Users/NULL/Pictures/Upgrade.gif</image>
    <image>C:/Users/NULL/Pictures/Pet.png</image>
    </server>

    <guild id="6424069110828181">
    <name>Test Guild</name>
    <advertchannel>658936539803418624</advertchannel>
    <commandchannel>658936539803418624</commandchannel>
    <user>304558905306906624</user>
    <delay>25000</delay>
    </guild>

    </advertisement>

The error occurs on the second roughly half way through the file, just above

<server name="Test Server"> 

Any idea what I'm doing wrong, I'm still very new XML(this being the first XML file I've parsed) but I cannot see anything wrong.

Answer 1

You cannot have multiple root elements in one XML document for it to be well-formed.

You would either have to

1. split up the document, or

2. wrap the entire contents in a new root element, eg

   <advertisements> <advertisement> <!-- ... --> </advertisement> <advertisement> <!-- ... --> </advertisement> </advertisements>

Answer 2

Each XML document has exactly one single root element.
