xml-analyser

一个工具，可以显示任意XML文件中元素使用的各种统计数据。

用法

xml-analyser example.xml

如果example.xml看起来像这样

<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 输出如下

{
    "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
    }
}

截断XML内容

使用--truncate选项的工作方式不同：传递给此工具的XML文件将被截断，通过找到具有两个或更多相同类型子元素的元素，并截断到仅包含这两个元素。

这可以将大型XML文件减少为更易于理解的形式。

给定一个如下的示例文档

<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>

以下命令

xml-analyser example.xml --truncate

将返回以下内容

<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>
