Interpreting the XML Response

Web services respond in XML. The StockQuote Web service responds with 16 different data elements for each trade symbol. Each data item is enclosed within a separate tag. For example, the <High> tag includes the high value of the symbol during the current trading session:

<High>64.70</High>

The market capitalization is denoted by the <MktCap> tag. Notice that the data includes the units of measures (B for Billions):

<MktCap>346.3B</MktCap>

Here is an example listing of the XML response for the symbols YHOO, IBM, and MSFT:
