Comparing the XML Output

This task shows how to compare the V4 and V5 classes and attributes. This task should be performed after you have exported the V4 project registration model and the V5 feature dictionary.
Your goal is to have a mapping table that shows the V4 classes and attributes you want to import and their corresponding V5 classes and attributes. Once you have converted and exported the V4 and V5 classes and attributes, the two must be compared to determine which ones do not exist in V5. This is done by a tool developed for the purpose. Once you have run this tool it will produce three files which tell you: which classes have problems (do not exist in the mapping table or the XML file of V5 classes), which classes need to be added to V5 and an overall report of what the tool has performed.

This step is not needed if you did not define new classes and attributes in V4.

Before you begin this process you must set the directory path - this tells the tool the directory path in your installation. Open a command prompt and move to the directory intel_a\code\bin.

  • In Windows,  press Enter after typing: set AECMIGR_DIRECTORYPATH= XXX\startup\EquipmentandSystems\MigrationDirectory where XXX is the directory path to your installation.
  • Do the same in Unix, but replace "set" with "export".
  • The user can check the current path by executing the comparator, or executing CATAecDictionaryComparator -h. The comparator will show the path as the first line of output.

1. To run the tool open a command prompt, change to the directory ...intel_a\code\bin, and enter the following: CATAecDictionaryComparator -i (V4file) (V5file) -m (name of mapping table) -o (name for output) 


  • (V4file) is the XML file which contains the V4 classes. It must include the XML extension.
  • (V5file) is the XML file which contains the V5 classes. It must include the XML extension.
  • (name of mapping table) is the name of the mapping table against which you want to compare. The default mapping table provided with this application is V4ToV5ObjectMapping.csv. You must include the .csv extension. The mapping table is in the following directory: intel_a\startup\EquipmentAndSystems\MigrationDiretory\Dictionary\Mapping Table
  • (name for output) is the name for the three output files. If you enter the name MAR, for instance, then three files will be produced: MAR.html, MAR.xml and MAR.csv.

An entry may look like this: CATAecDictionaryComparator -i Preg_ALL.xml catpiping.xml -m V4toV5ObjectMapping.csv -o MAR

2. When the tool (called Comparator) has finished running it will produce three reports and place them in the following directories: XML and CSV files in  intel_a\startup\EquipmentandSystems\MigrationDirectory\Dictionary\DDL_Files and the HTML file in ...\Reports.

Open the HTML file in a Web browser to see a full report.  The report begins with a table of contents that is hyperlinked to the entries. (The names in parentheses are internal names.) The entries in the report are color coded as follows:

  • Green: No action was taken. The V4 class appears in the mapping table and the XML file of V5 classes.
  • Blue: The V4 class appears in the mapping table, but not in the V5 XML file.
  • Red: The V4 class was not found in the mapping table or V5 XML file.
  • Orange: V5 mapping does not exist in the mapping table ("no mapping"), or is badly mapped.

3. Open the XML file (using a text editor like Wordpad) to see a list of the classes that do not exist in the V5 feature dictionaries and can be imported.

4. Open the CSV file using Microsoft Excel. It will look similar to the image below, except that it will not have the entries shown in the first line (shaded red).

In the first three columns this table displays existing classes in V4. You should fill in the 4th, 5th and 6th columns with  whatever you want the corresponding entry to be in V5. In column 7 you should enter the domain, or application. (PIP=Piping Design, PID= Piping and Instrumentation Diagrams, EQT= Equipment Design, HVA=HVAC Design, etc.)

An asterisk in the Attribute column indicates that the entry is a class. If it has attributes then the lines that follow it will list the attributes under the same class name. In the example above, Line 2 shows a class. Lines 3, 4 and 5 show that the entries are attributes of the class Piping Line and are called Size, Part Description and Design Speed.

NOTE: V5 entries should refer to the internal name of the class or parent. The internal name is the name within the application and is not the one the user sees. Frequently it is similar, though, and the class name Piping Line may have the internal name PipingLine. You can find the internal name by looking at the V5 XML file where it's referred to as Name and Superclass.

5. Once you have entered the information you need to copy and paste it into the mapping table - in the current example it is V4ToV5ObjectMapping.csv, found in intel_a\startup\EquipmentandSystems\MigrationDirectory\Dictionary\MappingTable.  However, you should not directly modify the table the table with the .csv extension. In this same directory you will find a table with the same name but with the extension .xls. Modify this table, save it, and then save it again as a .csv file also. It is faster for this application to read .csv files.

6. If you have V4 classes and attributes that do not have equivalent classes and attributes in V5 then you must repeat the steps explained in Importing the XML Output.

You can repeat these steps as many times as you want - until you are satisfied that your mapping table has all the V4 classes and attributes you want and the corresponding V5 classes and attributes.
