Configuring XML formatted output

You use the XMLOUT tool to configure the contents and structure of XML formatted output from the StreamServer. With the XMLOUT tool, you can configure the following:

•	Indentation, empty elements, and escape sequences

The XML structure in the output will by default be automatically indented, and empty elements will be displayed as </element>. Characters <, >, etc. will by default be substituted with numeric sequences. To change the default settings, you must select Tools > Options and edit the options. See Options dialog box.

•	The XML structure

Create the structure of elements, attributes, text nodes, processing instructions, etc.

•

Blocks

Recurring data is defined as fields within blocks in the Event configuration. The block and field configuration defined in the Event tool are available in a separate Event view in the XMLOUT tool. In the XMLOUT tool, you drag the blocks from the Event view, and drop them on the appropriate element in the Process view. See Adding blocks.

•	Text nodes

A text node is either a variable, static text, or field. You can add text nodes to elements, attributes, etc. See Adding text nodes.

•	Free blocks

Free blocks can be added before the first instance of a main block, after the last instance of a main block, or be invoked using the CallBlock scripting function. See Free blocks.

•	Sort criteria for blocks

For each block defined in the XMLOUT tool, you can specify one or more sort keys. When the StreamServer processes the data, it will sort the blocks according to the sort keys. See Sorting.

•	Output format for fields and variables

You can specify which format to use for the output from fields and variables. See Output format for fields and variables.
