Capturing Specific Data Using Batch Script

In the realm of scripting and automation, dealing with XML files often poses the challenge of extracting relevant data efficiently. If you've found yourself needing to capture specific pieces of information from several XML documents and storing it in a variable or a list, you're in the right place! This guide aims to help you successfully extract values, particularly the <Passed> value from the <TestResults> tags in your XML files. Let's dive into the solution, structured in an easy-to-follow manner.

Understanding the Problem

Imagine you have multiple XML files which follow a similar structure. Among the various tags, you're particularly interested in the data encapsulated within the <TestResults> tag that contains an index defined as Sensor1. This tag further holds a child element <Passed>, which indicates whether the test passed or failed.

For instance, consider the following sample XML snippet:

Your goal is to extract the value (either true or false) found between the <Passed> tag corresponding to Sensor1. Let's explore how to approach this using Batch Script.

Solution Overview

The solution will depend on whether there is:

Just one <Passed> tag within each XML file, or

Multiple <Passed> tags that could be present.

I will outline both scenarios to ensure flexibility for your needs.

Scenario 1: Single Passed Tag

If you are certain that each XML file contains only one <Passed> line that you are interested in, the following Batch Script will suffice:

Explanation:

The for %%f in (*.xml) loop processes each XML file in the current directory.

The findstr "Passed" command is used to locate lines that contain the <Passed> tag.

The for /F loop then extracts the relevant piece of information (true/false) you need.

Scenario 2: Multiple Passed Tags

In cases where there are many <Passed> tags but you are only interested in the one following the <TestResults index="Sensor1">, use the following script:

Explanation:

Similar to the first script, this one processes each XML file but includes more complex logic.

The nested for-in loops help pinpoint the line with TestResults index="Sensor1", then look for the subsequent <Passed> tag only after that line is found.

Conclusion

With these two scripts, you can easily extract the specific test results from your XML files according to your needs. Whether dealing with a single or multiple <Passed> tags, Batch Script provides a feasible way to automate the process of data extraction.
