This is a Go application that parses an XML file or an XML response from a URL, counts the child nodes for each XML element, and prints the counts to the console.

1. Make sure you have Go installed on your machine.
2. Clone this repository or copy the source code into your working directory.
3. Build the project using the following command:

   go build -o sir

The application accepts a single argument that specifies the path to an XML file or a URL containing an XML response.

./sir <filepath/url>

1. Processing a local XML file:

   ./sir sample.xml

2. Processing an XML from a URL:

   ./sir https://example.com/sample.xml

For an input XML file or URL containing:

<root>
  <child1>
    <subchild1 />
  </child1>
  <child2 />
</root>

The output will be:

root: 2
child1: 1
