Parsing XML Documents

• To get the number of items (2), use the XPath expression:

  count(/items/item)

• The total number of children (2) can be obtained as:

  count(/items/*)

• To select attributes, use an @ followed by the name of the attribute:

  /items/item[2]/product/price/@currency

• To find out the name of a child in a document with variable/unknown structure:

  name(/items/item[1]/*[1])

  The result is the name of the first child of the first item, or product
