I have a REST web service that creates a XMLDocument I am a bit confused on how access the inner text in FormattedPrice using XMLNode. I can grad offers but that will give me all the inner text.
<Offers>
<Offer>
<OfferListing>
<Price>
<Amount>1067</Amount>
<CurrencyCode>USD</CurrencyCode>
<FormattedPrice>$10.67</FormattedPrice>
</Price>
</OfferListing>
</Offer>
</Offers>
A quick walk-through of XPath will help immensely if you're using the Xml DOM.
This should meet your immediate need:
XmlNode n = doc.DocumentElement.SelectSingleNode("Offer/OfferListing/Price/FormattedPrice");
That will get you the first Offer's Formatted price (and assumes that your Offers node is the root). Other mechanisms exist in XPath that are a bit less brittle and that's where a tutorial would help you.
You are probably be best off using XPath.
XmlDocument doc = ...;
XmlNode fPrice;
XmlElement root = doc.DocumentElement;
fPrice= root.SelectSingleNode("/Price/FormattedPrice");
return fPrice.InnerText;
Here's a good example: http://www.codeproject.com/KB/cpp/myXPath.aspx
Use XElement to parse it:
string tmp = @"
<Offers>
<Offer>
<Price>
<Amount>1067</Amount>
<CurrencyCode>USD</CurrencyCode>
<FormattedPrice>$10.67</FormattedPrice>
</Price>
</Offer>
</Offers>";
XElement xml = XElement.Parse(tmp);
string formatedPrice = (string)xml.XPathSelectElement("/Offer/Price/FormattedPrice");
This should grab the $ amount:
var price = doc.SelectSingleNode(@"//Offer/Price/FormattedPrice");
string priceText = price.InnerText;
Load what you want into a XmlNodeList and then pull one explicitly or loop through them...
XmlNodeList pricesList = xmlDoc.GetElementsByTagName("FormattedPrice");
string firstPrice = pricesList[0].InnerText;
First off, your XML is invalid....you are missing the starting OfferListing tag.
Here is yet another option to grab the node text.
var xmlString = "<Offers><Offer><OfferListing><Price><Amount>1067</Amount<CurrencyCode>USD</CurrencyCode><FormattedPrice>$10.67</FormattedPrice></Price></OfferListing></Offer></Offers>";
var xDoc = new XmlDocument();
xDoc.LoadXml(xmlString);
var formattedPrice = xDoc.GetElementsByTagName("FormattedPrice")[0].InnerText;
