Analyse the structure of an arbitrary XML file

Project description

xml-analyser

PyPI Changelog Tests License

A tool showing various statistics about element usage in an arbitrary XML file.

Usage:

xml-analyser example.xml

If example.xml looks like this:

<example>
  <foo>
    <bar a="1" b="2">
      <baz>This has text</baz>
    </bar>
  </foo>
  <foo>
    <bar a="1" b="2" c="3">
      <baz>More text here</baz>
    </bar>
    <baz d="1" />
  </foo>
</example>

xml-analyzer example.xml outputs this:

{
    "example": {
        "count": 1,
        "parent_counts": {},
        "attr_counts": {},
        "child_counts": {
            "foo": 2
        }
    },
    "foo": {
        "count": 2,
        "parent_counts": {
            "example": 2
        },
        "attr_counts": {},
        "child_counts": {
            "bar": 2,
            "baz": 1
        }
    },
    "bar": {
        "count": 2,
        "parent_counts": {
            "foo": 2
        },
        "attr_counts": {
            "a": 2,
            "b": 2,
            "c": 1
        },
        "child_counts": {
            "baz": 2
        }
    },
    "baz": {
        "count": 3,
        "parent_counts": {
            "bar": 2,
            "foo": 1
        },
        "attr_counts": {
            "d": 1
        },
        "child_counts": {},
        "count_with_text": 2,
        "max_text_length": 14
    }
}

Truncating the XML instead

The --truncate option works differently: the XML file passed to this tool will be truncated, by finding any elements with more than two child elements of the same type and truncating to just those two elements.

This can reduce a large XML file to something that's easier to understand.

Given an example document like this one:

<example>
  <atop title="Example 1" />
  <atop title="Example 2" />
  <atop title="Example 3" />
  <atop title="Example 4" />
  <foo>
    <bar a="1" b="2">
      <baz>This has text</baz>
    </bar>
    <bar a="2" b="2">
      <baz>This has text</baz>
    </bar>
    <bar a="3" b="2">
      <baz>This has text</baz>
    </bar>
    <bar a="4" b="2">
      <baz>This has text</baz>
    </bar>
  </foo>
  <foo>
    <bar a="1" b="2" c="3">
      <baz>More text here</baz>
    </bar>
    <baz d="1" />
  </foo>
  <foo>
    <bar a="1" b="2" c="3">
      <baz>More text here</baz>
    </bar>
    <baz d="1" />
  </foo>
</example>

The following command:

xml-analyser example.xml --truncate

Will return the following:

<example>
  <atop title="Example 1" />
  <atop title="Example 2" />
  <foo>
    <bar a="1" b="2">
      <baz>This has text</baz>
    </bar>
    <bar a="2" b="2">
      <baz>This has text</baz>
    </bar>
  </foo>
  <foo>
    <bar a="1" b="2" c="3">
      <baz>More text here</baz>
    </bar>
    <baz d="1" />
  </foo>
</example>
