Arrays and folders

[Trond Hoiberg]

I have an XML file with some data:

<Directlist>
<Directory>
<ID>1</ID>
<name>DirectoryRed</name>
</Directory>
<Directory>
<ID>2</ID>
<name>DirectoryBlue</name>
</Directory>
<Directory>
<ID>3</ID>
<name>DirectoryWhite</name>
</Directory>
</Directlist>

Is there a way i can read only the <name> (DirectoryRed, DirectoryBlue,
DirectoryWhite) into an array and then generate Folders using a method like
this (example):

public static void CreateDirectory(string directory)
{
string path = directory;
try
{
if (!Directory.Exists(path))
{
// Create the directory it does not exist.
Directory.CreateDirectory(path);
}
}
catch (Exception e)
{
MessageBox.Show("Creating directory failed: {0}", e.ToString());
}
finally {}
}

THe result will be 3 new folders
best regards

Hi Trond

Use XPath

XmlDocument doc = new XmlDocument();
doc.Load(<your XML in some form>);
XmlNodeList nodes = doc.SelectNodes("//name/text()");
foreach( XmlNode node in nodes)
{
if( !Directory.Exists(node.Value)
{
Directory.CreateDirectory(node.Value);
}
}

Yep, XPath is definitely thre most efficient (in terms of the amount of code you have to write) way of getting data out of an XmlDocument. But you have to be happy to take the hit (which for small documents isn't a big deal) to load the document into memory. For big documents you may have to drop down to using XmlReader but in most situations it isn't necessary.

One last thing, Xpath is *very* xml namespace sensitive. If the document you showed isn't exactly like the document you are processing (like there is a default namespace or something) then you have more work to do.
