C# Ramblings

[Animal]

I'm taking on a pet project using C# and XML to store data for a "fitness diary". The first big item I need to get out of the way is reading, writing, and navigating the data stored in XML files.

Initially I was playing around with the System.Xml.XmlTextReader (http://msdn.microsoft.com/en-us/library/system.xml.xmltextreader.aspx) class. However, per MSDN, this particular class is only useful if you are trying to read the XML file sequentially.

For now, the System.Xml.Document (http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx) class will have to do. There is a good possibility that the System.Xml.DataDocument (http://msdn.microsoft.com/en-us/library/system.xml.xmldatadocument.aspx) will also be used or may even replace the use of System.Xml.Document (http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx) altogether since it is more closely tied with DataSets.

Bah, I just need some place to keep my crap together. I suppose I could use a text file or something on my computer but this is better. Once I have enough information, I'm gonna write up a short tutorial and put it on my blog.

No, I deliberately posted it here. This is a public place but wont necessarily be viewed as spam. Those that wish to comment on my code or thought process may feel free to do so. Others can simply ignore the thread or just come in and poke fun at me! :lol:

Consider the following XML:
<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE user [
<!ATTLIST profile id ID #REQUIRED>
]>

<user>
<profile id="0">
<name>Mickey Mouse</name>
<birthday>74</birthday>
<height>73</height>
<weight>275</weight>
<goal>250</goal>
</profile>
<profile id="1">
<name>Joe Smith</name>
<birthday>74</birthday>
<height>68</height>
<weight>230</weight>
<goal>200</goal>
</profile>
</user>

We can populate a listview to look as follows:

The code to accomplish this:
//obtain the path to "my documents"
//string getFitXML = Environment.GetFolderPath(Environment.SpecialFolde r.Personal).ToString();
string getFitXML = "E:/Documents/Visual Studio 2008/Projects/GetFit/GetFit/profiles.xml";
//check to see if the XML file exists
if (File.Exists(getFitXML))
{
XmlTextReader rdrProfileID = new XmlTextReader(getFitXML);
//rdrProfileID.WhitespaceHandling = WhitespaceHandling.None;
int i = new int();
i = 0;
rdrProfileID.MoveToContent();
while (rdrProfileID.Read())
{
if ((rdrProfileID.Name == "profile") && (rdrProfileID.HasAttributes))
{
lvwProfiles.Items.Add(rdrProfileID.GetAttribute("id"));
}
if ((rdrProfileID.Name == "profile") && (rdrProfileID.NodeType == XmlNodeType.EndElement))
{
i++;
}

switch (rdrProfileID.NodeType)
{
case XmlNodeType.Text:
lvwProfiles.Items[i].SubItems.Add(rdrProfileID.Value);
break;
}
}
}
else
MessageBox.Show("The " + getFitXML + " file was not found");

That code will add as many profiles as there are. It's very crude, error prone, and if you change the structure of the XML, you are going to break it. Still, it's a good foundation to build on.
