To extract information from an XML document, you'll need to read it and convert into the DOM tree form. There is an easy way to do this, and a full-featured way to do it. In order to select between these methods, it is necessary to think about whether the document needs a correct base URI (see Section 2.5, “Base URI”).
If you don't need to supply a correct base URI, this technique gives you a DOM document object that represents an XML source document in any of four forms:
A string that contains the entire document, e.g.,
sex='m' >Rover</dog ></dog-list >"
A file containing the document, as a readable file object.
A string that names the file containing the document.
The URI of the document, if it is available at that location.
To use this technique, first import the relevant modules:
from Ft.Xml import Parse
Then, to transform an XML document into a DOM tree:
doc= Parse (
is any of: a string containing the
document, a stream from which to read the document, the
name of the document file, or the URI of the document.
Parse() function returns a DOM
Document node, that is, the root of the document
tree. For further information on the structure of this
tree, see Section 4, “The structure of a DOM tree”.
does not exist, this function will raise
Ft.Lib.UriException. If it exists but is
