Load and save methods usage examples
Load and save method usage examples for the xml.DomDocument
class.
You can load an existing XML document. Before loading an XML document you need to create the DomDocument object.
A DomDocument
can load files using different URI: http://,
https://, tcp://, tcps://,
file:// and alias://.
See getErrorsCount()
and getErrorDescription()
to retrieve error messages related to XML document.
load("data.xml")
load("http://www.w3schools.com/xml/cd_catalog.xml")
load("https://localhost:6394/ws/r/calculator?WSDL")
load("file:///data/cd_catalog.xml")
load("tcp://localhost:4242/")
load("tcps://localhost:4243/")
load("alias://demo")
In
the example the demo
alias is defined in fglprofile as
ws.demo.url = "http://www.w3schools.com/xml/cd_catalog.xml"
loadfromstring("<List> <elt>First element</elt>
<elt>Second element</elt> <elt>Third element</elt> </List>")
The
example, produces a subtree with a root node List
and three nodes
elt
and three textnode
.DomDocument
can be saved at different URI beginning with:
http://, https://, tcp://,
tcps://, file:// and alias://.
save("myfile.xml")
save("http://myserver:8080/data/save1.xml")
save("file:///data/save.xml")
save("tcp://localhost:4242/")
save("alias://test")
In
the example the test
alias is defined in fglprofile as
ws.test.url = "http://localhost:8080/data/save3.xml"
The saveToString
method saves the DomDocument
in a string.
See getErrorsCount()
and getErrorDescription()
to retrieve error messages related to XML document.
The normalize
function emulates a DomDocument
save and load. It
can be called at any stage of the DomDocument
building. This removes empty Text
nodes and sets namespace declarations as if the document had been saved.
