MalExporter

simple tool to import xml data and export it to csv or into an postgresql database

Build

Visual Studio or dotnet build can be used to build the project.

Dependencies

  • CliFX
  • Npgsql

Usage

CSV

MALExporter.exe csv <filename> <tag> <csvfile> convertes the data in the <tag> blocks of the xml file into an equivalent csv file.

If --force is added to the command a existing csv file will be overwritten. If -f is added a renaming scheme of the form xmlfield=csvfield,... can be added which rewrites the xml column xmlfield into csvfield while exporting.

SQL

MalExporter.exe sql <filename> <tag> <sqlconnectionstring> <tablename> convertes the data in the <tag> block of the xml file into an equivalent PostgreSQL table.

The <filename>and <tag> parameters work in the same way as in the csv part. <sqlconnectionstring> has to be a a Npgsql-compliant connection string to a PostgreSQL database. <tablename> is the table which is created by MalExporter for the export.

As in the CSV part --force can be added to the command to overwrite an existing PostgreSQL table. If -f is added a renaming scheme of the form xmlfield=sqlfield,... can be added which rewrites the xml column xmlfield into sqlfield while exporting.

Examples

First example

Let test.xml be the following XML file:

<?xml version="1.0" encoding="utf-8" ?>
<root>
	<child>
		<test>first</test>
		<test2>second</test2>
	</child>
	<child>
		<test>third</test>
		<test2>forth</test2>
	</child>
</root>

MalExporter.exe csv test.xml child test.csv will create the following CSV file:

test,test2
first,second
third,forth

Second example

It is also possible to only export some of the columns. Let test2.xml be the following XML file:

<?xml version="1.0" encoding="utf-8" ?>
<root>
	<child>
		<test>first</test>
		<test2>second</test2>
        <test3>test3</test3>
	</child>
	<child>
		<test>third</test>
		<test2>forth</test2>
        <test3>test3-2</test3>
	</child>
</root>

MalExporter.exe csv test2.xml child test2.csv -f test,test3=rename3 will create the following CSV file:

test,rename3
first,test3
third,test3-2

It can be seen that only the xml values for test and test3 were exported into the csv file and the name of the test3 column was renamed to rename3.
