This document covers the following topics:
These system variables, which are available when using the
PARSE statement, are
only valid in the current loop context.
| Format/length: | I4 |
| Content modifiable: | No |
This system variable contains the column where the parser is currently working at.
In mainframe environments, it always points to the start of the current markup element.
(r)
notation after *PARSE-COL is used to
indicate the statement label or source-code line number of the
PARSE statement. If
(r) is not specified,
*PARSE-COL represents the column where the parser
in the currently active processing loop is working at.
| Format/length: | I4 |
| Content modifiable: | No |
This system variable contains the level of currently nested elements.
(r)
notation after *PARSE-LEVEL is used to
indicate the statement label or source-code line number of the
PARSE statement. If
(r) is not specified,
*PARSE-LEVEL represents the level where the parser
in the currently active processing loop is working at.
| Format/length: | A (dynamic) |
| Content modifiable: | No |
This system variable contains the namespace URI of the current
element/attribute, if the element/attributes belong to a namespace. If the
NAME (operand3) value of the
PARSE statement is
empty, then there is also no namespace and *LENGTH(*PARSE-NAMESPACE-URI)
is set to 0.
(r)
notation after *PARSE-NAMESPACE-URI is
used to indicate the statement label or source-code line number of the
PARSE statement. If (r) is
not specified, *PARSE-NAMESPACE-URI represents the
namespace URI of the current element/attribute in the currently active
processing loop.
| Format/length: | I4 |
| Content modifiable: | No |
This system variable contains the row where the parser is currently working at.
(r)
notation after *PARSE-ROW is used to
indicate the statement label or source-code line number of the
PARSE statement. If
(r) is not specified,
*PARSE-ROW represents the row where the parser in
the currently active processing loop is working at.
| Format/length: | A1 |
| Content modifiable: | No |
This Natural system variable is automatically created for each
PARSE statement
issued.
This system variable contains the type of the delivered data.
(r)
notation after *PARSE-TYPE is used to
indicate the statement label or source-code line number of the
PARSE statement. If (r) is
not specified, *PARSE-TYPE represents the type of
the delivered data in the currently active processing loop.
Possible values for ASCII-based systems are:
| ? | Processing instruction (but not first <?XML ...
?>).
|
|---|---|
| ! | Comment. |
| C | CDATA section. |
| T | Starting tag. |
| @ | Attribute (on mainframes: § or @, depending on session code page and terminal emulation). |
| / | Closing tag. |
| $ | Parsed data. |
