Constructing simple XML?

[Brett Romero]

What is the best way to construct this type of XML

<ROOT><Person PersonId=\"1000\" /><Person PersonId=\"1001\" /><Person
PersonId=\"1002\" /></ROOT>

when I'm getting back only the three numerical values? The is occuring
in a loop and I'm getting a variable such as PersonID, which holds the
values. The XML needs to be a string but I'd like to see what a more
complex type would look like (XMLdoc type?).

Thanks,
Brett

This pretty much covers the creation part:

to get the two backslashes in there.

Brett, you create attribute nodes just like element nodes. Here's the code
from the link you posted, modified to create the XML in your original post:

XmlDocument xmldoc;
XmlAttribute attr;
XmlElement elem;
XmlElement root;

xmldoc=new XmlDocument();

//let's add the XML declaration section
XmlNode xmlnode=xmldoc.CreateNode(XmlNodeType.XmlDeclarati on,"","");
xmldoc.AppendChild(xmlnode);

//let's add the root element
elem=xmldoc.CreateElement("ROOT");
xmldoc.AppendChild(elem);
root = elem;

//add person elements. assume you have some data structure called ListOfIds
containing the numbers
foreach (int personId in ListOfIds)
{
elem = xmldoc.CreateElement("Person");
attr = xmldoc.CreateAttribute("PersonId");
attr.InnerText = personId.ToString();
elem.Attributes.Append(attr)
root.AppendChild(elem);
}

Thanks.

If I try to read my file, which looks like this:
<?xml version="1.0"?>
<ROOT>
<Person PersonID="83615">
</Person>
</ROOT>

I get this error:
"The data at the root level is invalid. Line 1, position 1."

I'm using:
xmlDoc.LoadXml(@"C:\Documents and Settings\BROMERO\My
Documents\testing.spec");

I'm not sure if it is referring to the LoadXML method or the file. Any
ideas?

The <?xml version="1.0"?> part was generated with the XMLDeclaration
enumerator.

Thanks,
Brett

Hi Brett,
the LoadXML method assumes the string you are passing as a parameter is
XML, not a file path. If you want to load XML from a file use the
XmlDocument.Load method and pass in the file name.

Hope that helps

For really quick XML construction, I suggest looking at the XmlWriter class
(and its descending implementations).
