Basic XmlTextReader question

[Gustaf Liljegren]

I shall make a make a function that will read an XML file, looking for
elements like this

<context id="A1">
<period>
<instant>2001-01-01</instant>
</period>
</context>

or this

<context id="A2">
<period>
<startDate>2001-01-01</startDate>
<endDate>2001-12-31</endDate>
</period>
</context>

Here's the code I've written so far:

static string[] GetContext(string id)
{
XmlTextReader r = new XmlTextReader(file_document);
string[] period = new string[2];

while(r.Read())
{
if(r.IsStartElement("context", NS_XBRL) &&
r.GetAttribute("id") == id)
{
// ?
}
}
}

After I have found the <context> element, what is the right way to
proceed to get the dates? I know I can step forward by using r.Read()
but I'll probably just get lost that way, and it doesn't seem so
robust. I'd like to say "step forward to the <period> element". Maybe
XmlTextReader is the wrong tool for this, but I hope to avoid loading
the whole file at once.

Thanks!

What's wrong withe a pair of Read() and checking the Name property
of the reader?
