A CSV file typically has an extension '.csv'.

A CSV file can be created directly in a plain text editor (e.g. Wordpad/Notepad), in Excel (by saving as a CSV), or by some other application.

Whenever an analysis model is run it will carry out a number of tasks e.g. read a number of files, generate a number of stream sets, export a number of files. It is possible to configure an analysis model so that in a single analysis session it will actually run several times. When a model is configured in this way, each time it runs is termed a 'cycle' and all of the items processed or generated during that cycle (i.e. the files processed, stream sets created, files exported etc) are flagged with the cycle number. This cycle number is visible in the Log File for that analysis run on each of the relevant tabs showing files and stream sets processed.

The most common reason for configuring a model in this way is to allow a number of files to be processed in a single analysis session but to have the results from each file saved in a separate stream set. In this way, whenever a file fails to process the user can simply rollback the stream sets associated with that file rather than rolling back all of the stream sets associated with all of the files for the whole analysis session.

To achieve this, a model is configured with a push pipe from the final stream in the model pointing back to itself. This push pipe is then given positive offsets. The file collector at the start of the model is then configured to process a single file at a time. When this model is run the file collector will read in one file, process it to create a stream set (or a chain of stream sets if there are several streams in the model) and will flag the file processed, the stream sets generated and any associated output files with the cycle number 1. When the last stream in the model has finished producing its stream set it will send a notification to itself down the push pipe. This notification (because of the positive offsets) will be taken as a signal to create another stream set which will effectively cause the whole model to run again. This second run of the model will be deemed to be cycle 2 and all files processed, stream sets produced or files output will be flagged with this cycle number.

When later viewing the log files the user can see which items were processed in which cycle and can choose how many cycles to roll back. In the case where the last file processed was unsuccessful the user can therefore choose to only roll back the last cycle.

When parsing an XML response, the XPath on an HTTP Collector determines the node in the XML response that will cause an output record to be generated. In general, XML node names are relative to namespaces, and are referred to by namespace aliases. An XPath can use any XML Namespace alias defined by the HTTP Datasource linked to the HTTP Collector .

An XPath expression on an HTTP Collector determines the node in the XML response that will cause an output record to be generated.

An XPath is a '/'-separated list of node names.

If any of the node names in the XPath use non-default namespaces, these may be defined in XML Namespaces
