XML newbie question - how to structure my files

Hello

I am starting a new project in which I have a create and the read XML files in VB.net

I am pretty much free to structure my files in which ever way I see fit. On the reading side I have to use the MSXML libraries / parser.

My file would tentatively have the following structure

Item1
Property1
Property2

Item2
Property1
Property2

etc

As such I have come up with
<?xml version="1.0" encoding="UTF-8"?>

<item>
	<itemnum>1</itemnum>	
	<property>
    my property value
    </property>
</item>

<item>
	<itemnum>2</itemnum>	
	<property>
    some other property value
    </property>
</item>

Open in new window


which will not parse correctly.

I'm sure this is an obvious newbie question but how should I structure my files ?

you will need to wrap item elements in one root element
<items> would be a good idea

like this

<items>
    <item>
        <itemnum>1</itemnum>
        <property> my property value </property>
    </item>

    <item>
        <itemnum>2</itemnum>
        <property> some other property value </property>
    </item>
</items>

Open in new window

aha - gotcha - so you always need a "root" node and after that you can go about your merry way :) ?

From the processing point of view actually there is a general tendency to group similar elements in a container

<?xml version="1.0" encoding="UTF-8"?>
<items>
    <item>
        <itemnum>1</itemnum>
        <properties>
            <property> my property value </property>
            <property> my property value 2 </property>
        </properties>
    </item>

    <item>
        <itemnum>2</itemnum>
        <properties>
            <property> some other property value </property>
            <property> some other property value 2</property>
        </properties>
    </item>
</items>

Open in new window


it makes the processing easier

correct, an XML document can only have one root element

Thanks - things are starting to take shape...

I have another issue with the generated code where (I guess) the online editor I am using a playing some tricks on me. Say I have

<property> this is a test... </property>

it translates into

<property> this is a test &hellip; </property>

which will create a parsing error.

Again pretty sure these are minor and obvious gotchas but wondering how to avoid them...

yes that is an 'online' issue
&hellip; is a character entity (consider it a macro) which is allowed in an XML document if you also declare it in the document.
HTML works the same way, but there the entities are hard coded in the browser
so "&hellip;" makes sense to a browser in a HTML file, it only makes sense in an XML if you tell the XML what it is
The safest around it is to replace the hellip with the numeric character entity
"&#133;"
