The variable contains the parsed XML. When used in the preceding Lingo, it
gParserObject
refers to the root node of the XML document. The Lingo term refers to the first level
child[1]
of nested tag, which is the tag.
e1
To find out what kind of node the first tag is, use the function, as shown in the following
type
example:
put gParserObject.child[1].type
-- #element
To refer to nodes that are nested more than one level deep, use more than one level of child
reference. The following Lingo returns the name of the first tag that is nested within the tag:
e1
put gParserObject.child[1].child[1].name
-- "tagName"
The following Lingo returns the name of the second tag that is nested within the tag:
e1
put gParserObject.child[1].child[2].name
-- "e2"
To refer to text data that occurs within a particular tag, use the property. The text is a child
text
node of the tag that contains it, so you need an additional level of child reference. This Lingo
returns the following string, which appears inside the tag from the previous XML example:
e2
put gParserObject.child[1].child[2].child[1].text
-- "element 2"
In this example, the variable refers to the root node of the XML. The
gParserObject child[1]
refers to the tag, which occupies the first level down in the XML's nested structure. The
e1
refers to the second tag within the tag, which is the tag. The last refers
child[2] e1 e2 child[1]
to the text within the tag, which is . Finally, the property is specified, so Lingo
e2 element 2 text
returns the text of the node rather than any other property of the node.
The fourth child of the tag is a line of text that reads . This text is a child
e1 here is some text
the same as the XML tags that precede it. You can get the type of this child the same way you get
other children.
The following Lingo returns the type of the fourth child of the tag:
e1
put gParserObject.child[1].child[4].type
-- #text
This Lingo returns the text of the fourth child of the tag, as shown in the following example:
e1
put gParserObject.child[1].child[4].text
-- "
here is some text
"
The text element includes the white space for Return, Space, and Tab characters as well as the
string .
" here is some text "
You can use the Lingo function to determine the number of children that exist at a
count
particular level of the XML structure. The following Lingo returns the number of children at the
2nd level in the previous XML example:
put gparser.child[1].child.count
-- 4
