XMLFileExtract

Use this form set level rule when the extract list loaded by the transaction contains the name of an external file source for the XML tree.

Note

The extract list and the XML tree are separate items. Even if you are only using an XML file as the source of the transaction, there will be two copies of the information in memory — one as the extract list and one as the XML tree.

Syntax

;XMLFileExtract;;parameter;

For the parameter, you can use one of the following:

FILE=<filename>

Where filename is the name of the XML file, including path information.

INI=group,option

Where group and option are defined in the INI files

SCH=offsetofmask,<searchmask> offsetofdata,lengthofdata

Parameter	Description
offsetofmask	the offset of the search mask
offsetofdata	the offset where the path and the file name start
lengthofdata	the length of the file name

GVM=<globalvariablename>

Where globalvariablename is the name of a GVM that contains the file name.

Here are examples of how you can use this rule:

;XMLFileExtract;2;FILE=SAMPCO.XML;

;XMLFileExtract;2;INI=Group,Option;

;XMLFileExtract;2;SCH=11,FILENAME 20,20;

;XMLFileExtract;2;GVM=FileNameVar;

Keep in mind...

Begin each XML transaction with the XML declaration.
In the RunMode control group, set the XMLExtract option as shown here:

< RunMode >

XMLExtract = Yes

You place the rule in different locations in the AFGJOB.JDT file, depending on the mode in which you are running. For multi-step mode, place the XMLFileExtract rule after the LoadExtractData rule, as shown here:

;LoadExtractData;;

;XMLFileExtract;2;FILE=SAMPCO.XML;

For single or two-step mode, place the XMLFileExtract rule after the NoGenTrnTransactionProc rule, as shown here:

;NoGenTrnTransactionProc;;

;XMLFileExtract;2;FILE=SAMPCO.XML;

Remember that the system decides whether to search the extract list or the XML tree by checking to see if the search mask starts with an exclamation mark (!). The exclamation mark indicates that this is an XML path string. The system ignores the exclamation mark when it performs the XML path search.

To preserve the space when mapping data, use two exclamation marks (!!). Otherwise, the system assumes it should remove the leading white space.

When running NoGenTrnTransactionProc (single or two-step mode) and the INI option is set to load the XML file, so there is no need to place XMLFileExtract rule in the AFGJOB.JDT file. Doing so makes the system load the XML file twice.
