xmlReader (Type of variable)

In french: xmlLecteur

The xmlReader type is used to read an XML document without loading it in memory. The characteristics of this XML document can be read by several WLanguage properties.

Note: See Declaring a variable for more details on the declaration of this type of variable and the use of WLanguage properties.

Example

MyNode is xmlNode
MyNode..Type = XMLTag
MyNode..Name = "MyNode"
MyNode..Text = "Text of node"

Reader is xmlReader = XMLOpenReader("file.xml")

FOR EACH Reader IN DEPTH
Trace(Reader..Type)
END

Reader2 is xmlReader = XMLOpenReader("file.xml")

FOR EACH x OF Reader2
IF Reader2..Type = XMLReaderStartTag _OR_ Reader2..Type = XMLReaderEmptyElementTag THEN
IF Reader2..Name = "config" THEN
FOR EACH y OF x
Trace(x..Name)
END
END
END
END
