(2013-02-08) Parsing A CSExport Generated XML File Into A Scoped CSV File

I needed to research the CSExport output. However, that’s an XML file and not really helpful in diagnosing the data in it. Converting it to a CSV, so that it can be loaded into Excel is much much better. So after some google magic, I found Carol Wapshere’s script. However, that script had two issues I needed to solve. At first it does not support multi-values and I needed to diagnose the proxyAddresses attribute. And secondly, because the Get-Content CMDlet is being used to read the XML file it chokes if the XML file size is too large. The error can be seen below.

Figure 1: Error Reading An XML File File That’s Too Large With The Get-Content CMDlet

-

I added logic to the script to also process multi-valued attributes when applicable and instead of using the Get-Content CMDlet, I read the XML file as shown in the script below. I was not able to specify the “MaxCharactersInDcoument” property when using the Get-Content CMDlet. The XML file I was reading was about 500 MB and it contained about 1000000000 characters. The method I use below does not have a limit and allows the configuration “MaxCharactersInDcoument” property if needed.

# Takes an XML file created by CSEXPORT, and produces a CSV file more suitable for opening in Excel.
# Supports both single-valued attributes and multi-valued attributes
#
# Before using the script:
#    * Define the attributes of interest
#    * Define the object types of interest. * means every object

When using the script you need to make adjustments to it before actually using it. This is shown below.

Figure 2: Configuring The Object Types And The Attributes To Be Parsed Into The CSV File

-

[1] you need to define the attribute list you want to parse in an array. The first 5 attributes are available for all object types in every connector.

[2] you need to define the object types you want to parse in an array.

To execute the script, see below.

Figure 3: Using The Script

-

.\FIM-Sync-Engine-Parse-CSExport.ps1 -sourceXML <Source XML> -targetCSV <Target CSV>

-

The CSV file in Excel should then look similar to

Figure 4: The CSV File In Excel

Happy diagnosing!
