  • 0

I want to load an XML file on the internet into a DataTable in C#. The XML is loaded from http://rates.fxcm.com/RatesXML and looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<Rates>
    <Rate Symbol="EURUSD">
        <Bid>1.29174</Bid>
        <Ask>1.29198</Ask>
        <High>1.29407</High>
        <Low>1.28723</Low>
        <Direction>-1</Direction>
        <Last>14:56:48</Last>
    </Rate>
    <Rate Symbol="USDJPY">
        <Bid>82.862</Bid>
        <Ask>82.885</Ask>
        <High>83.293</High>
        <Low>82.847</Low>
        <Direction>1</Direction>
        <Last>14:56:47</Last>
    </Rate>
    <!-- More like the above -->
</Rates>

Can I use the ReadXml method of the DataTable class to read the XML, or do I need some kind of http request to get it first into a string?

EDIT:
I’ve just written the following 

public DataTable GetCurrentFxPrices(string URL)
{
    DataSet ds = new DataSet("fxPrices");
    ds.ReadXml(URL);

}

and it is trying to read the data, but I am behind a corporate firewall. I’m really clueless now how to get around this. I get this error:

System.Net.WebException: The remote server returned an error: (407) Proxy Authentication Required.

In firefox I have an HTTP proxy set with a port number. Can I set that somewhere in my app?

    Yes, you can use ReadXml if the XML is in a single-table format.

    It may not come in in the format you expect, so you may need to explore the structure of the dataset a bit, but it works just fine.

    As a general rule when loading data from an XML file into a Datatable, I’d read it into a DataSet first and be sure it does not create more than one table. Any nesting int he XML usually results in multiple tables in a DataSet.

    This particular file, however, looks like it would import into a single table just fine.
