The following example shows a short XML document:
<?xml version="1.0"?>
<e1><tagName attr1="val1" attr2="val2"/><e2>element 2</e2><e3>element 3</e3>
</e1>
The following example is the same XML with its tree structure shown more clearly:
<?xml version="1.0"?>
<e1>
<tagName attr1="val1" attr2="val2"/>
<e2>element 2</e2>
<e3>element 3</e3>
</e1>
There are two ways to access a parsed XML document. You can use the
convert the document into a nested property list and use the list-access methods of Lingo or
JavaScript syntax, or you can use the special script methods of XML Parser Xtra to access the
parsed data directly.
The following script statement uses the
property list:
theList = gParserObject.makeList()
If you choose to make a property list with the
list, reflecting the tree structure of the XML.
Each element in the document is represented by its own property list, with another property list
for each child element that it contains. The name of the element is the property name, and the
content of the element is the property value. Attributes of an element are stored in a child list with
the name !ATTRIBUTES. The property list of attributes contains the name of each attribute and
its value. Character data has the property name !CHARDATA, and the value is the string
representation of the character data. A processing instruction is a property with the name
!PROCINST; its value is another two-element property list. The first property of this sublist is
NAME, and the value is the string that represents the name of the processing instruction. The
second property of the sublist has the name TEXT and contains the rest of the text in the
processing instruction.
The property list resulting from the previous XML example would look like the following code:
["ROOT OF XML DOCUMENT": ["!ATTRIBUTES": [:], "e1": ["!ATTRIBUTES": [:],
"tagName": ["!ATTRIBUTES": ["attr1": "val1", "attr2": "val2"]], "e2":
["!ATTRIBUTES": [:], "!CHARDATA": "element 2"], "e3": ["!ATTRIBUTES": [:],
"!CHARDATA": "element 3"]]]]
The following example is the same property list with its nested structure shown more clearly:
["ROOT OF XML DOCUMENT": ["!ATTRIBUTES": [:],
"e1": ["!ATTRIBUTES": [:],
"tagName": ["!ATTRIBUTES": ["attr1": "val1", "attr2": "val2"]],
"e2": ["!ATTRIBUTES": [:], "!CHARDATA": "element 2"],
"e3": ["!ATTRIBUTES": [:], "!CHARDATA": "element 3"]
]
]]
Together, the Lingo or JavaScript syntax statements that create a property list from a string of
XML data would look like the following examples:
global gParserObject
gParserObject = new(xtra "xmlparser")
method to convert the parsed data to a
makeList()
method, the result is a nested property
makeList()
method to
makeList()
