-## Xmind Parsing Method
-
-> v0.2.7+
-
-You can get the `Xmind` parsing method as follows:
-
-```js
-import MindMap from "simple-mind-map";
-
-console.log(MindMap.xmind);
-```
-
-The `MindMap.xmind` object has two methods attached:
-
-### parseXmindFile(file)
-
-Parsing the `.xmind` file and returning the parsed data. Note that this is
-complete data, including the node tree, theme, and structure. You can use
-`mindMap.setFullData(data)` to render the returned data to the canvas.
-
-`file`: `File` object
-
-### transformXmind(content)
-
-Convert `xmind` data. The `.xmind` file is essentially a `zip` file that can be
-decompressed by changing the suffix to zip. Inside, there is a `content.json`
-file. If you have parsed this file yourself, you can pass the contents of this
-file to this method for conversion. The converted data is the complete data,
-including the node tree, theme, structure, etc. You can use
-`mindMap.setFullData(data)` to render the returned data to the canvas.
-
-`content`: the contents of the `content.json` file within the `.xmind` zip
-package
-
-### transformOldXmind(content)
-
-> v0.2.8+
-
-For data parsing of the `xmind8` version, because the `.xmind` file in this
-version does not have a `content.json`, it corresponds to `content.xml`.
-
-`content`: the contents of the `content.xml` file within the `.xmind` zip

 For all configurations of theme, please refer to [Default Topic](https://github.com/wanglin2/mind-map/blob/main/simple-mind-map/src/themes/default.js). The `defineTheme`method will merge the configuration you passed in with the default configuration. Most of the themes  do not need custom many parts.

+# XMind parse
+
+> v0.2.7+
+
+Provides methods for importing `XMind` files.
+
+## Import
+
+```js
+import xmind from 'simple-mind-map/src/parse/xmind.js'
+```
+
+If you are using the file in the format of `umd`, you can obtain it in the following way:
+
+```js
+import MindMap from "simple-mind-map/dist/simpleMindMap.umd.min"
+
+MindMap.xmind
+```
+
+## Methods
+
+### xmind.parseXmindFile(file)
+
+Parsing the `.xmind` file and returning the parsed data. Note that this is
+complete data, including the node tree, theme, and structure. You can use
+`mindMap.setFullData(data)` to render the returned data to the canvas.
+
+`file`: `File` object
+
+### xmind.transformXmind(content)
+
+Convert `xmind` data. The `.xmind` file is essentially a `zip` file that can be
+decompressed by changing the suffix to zip. Inside, there is a `content.json`
+file. If you have parsed this file yourself, you can pass the contents of this
+file to this method for conversion. The converted data is the complete data,
+including the node tree, theme, structure, etc. You can use
+`mindMap.setFullData(data)` to render the returned data to the canvas.
+
+`content`: the contents of the `content.json` file within the `.xmind` zip
+package
+
+### xmind.transformOldXmind(content)
+
+> v0.2.8+
+
+For data parsing of the `xmind8` version, because the `.xmind` file in this
+version does not have a `content.json`, it corresponds to `content.xml`.
+
+`content`: the contents of the `content.xml` file within the `.xmind` zip

-import MindMap from "simple-mind-map";

-console.log(MindMap.xmind)

-`MindMap.xmind`对象上挂载了两个方法：
-
-### parseXmindFile(file)

-解析`.xmind`文件，返回解析后的数据，注意是完整的数据，包含节点树、主题、结构等，可以使用`mindMap.setFullData(data)`来将返回的数据渲染到画布上
-
-`file`：`File`对象
-
-### transformXmind(content)
-
-转换`xmind`数据，`.xmind`文件本质上是一个压缩包，改成`zip`后缀可以解压缩，里面存在一个`content.json`文件，如果你自己解析出了这个文件，那么可以把这个文件内容传递给这个方法进行转换，转换后的数据，注意是完整的数据，包含节点树、主题、结构等，可以使用`mindMap.setFullData(data)`来将返回的数据渲染到画布上
-
-`content`：`.xmind`压缩包内的`content.json`文件内容
-
-### transformOldXmind(content)

+## 引入
+
+```js
+import xmind from 'simple-mind-map/src/parse/xmind.js'
+```
+
+如果使用的是`umd`格式的文件，那么可以通过如下方式获取：
+
+```js
+import MindMap from "simple-mind-map/dist/simpleMindMap.umd.min"
+
+MindMap.xmind
+```
+
+## 方法
+
+### xmind.parseXmindFile(file)
+
+解析`.xmind`文件，返回解析后的数据，注意是完整的数据，包含节点树、主题、结构等，可以使用`mindMap.setFullData(data)`来将返回的数据渲染到画布上
+
+`file`：`File`对象
+
+### xmind.transformXmind(content)
+
+转换`xmind`数据，`.xmind`文件本质上是一个压缩包，改成`zip`后缀可以解压缩，里面存在一个`content.json`文件，如果你自己解析出了这个文件，那么可以把这个文件内容传递给这个方法进行转换，转换后的数据，注意是完整的数据，包含节点树、主题、结构等，可以使用`mindMap.setFullData(data)`来将返回的数据渲染到画布上
+
+`content`：`.xmind`压缩包内的`content.json`文件内容
+

+针对`xmind8`版本的数据解析，因为该版本的`.xmind`文件内没有`content.json`，对应的是`content.xml`。

+<blockquote>

+<p>提供导入<code>XMind</code>文件的方法。</p>
+<h2>引入</h2>
+<pre class="hljs"><code><span class="hljs-keyword">import</span> xmind <span class="hljs-keyword">from</span> <span class="hljs-string">&#x27;simple-mind-map/src/parse/xmind.js&#x27;</span>
+</code></pre>
+<p>如果使用的是<code>umd</code>格式的文件，那么可以通过如下方式获取：</p>
+<pre class="hljs"><code><span class="hljs-keyword">import</span> MindMap <span class="hljs-keyword">from</span> <span class="hljs-string">&quot;simple-mind-map/dist/simpleMindMap.umd.min&quot;</span>
+
+MindMap.xmind
+</code></pre>
+<h2>方法</h2>
+<h3>xmind.parseXmindFile(file)</h3>
+<p>解析<code>.xmind</code>文件，返回解析后的数据，注意是完整的数据，包含节点树、主题、结构等，可以使用<code>mindMap.setFullData(data)</code>来将返回的数据渲染到画布上</p>
+<p><code>file</code>：<code>File</code>对象</p>
+<h3>xmind.transformXmind(content)</h3>
+<p>转换<code>xmind</code>数据，<code>.xmind</code>文件本质上是一个压缩包，改成<code>zip</code>后缀可以解压缩，里面存在一个<code>content.json</code>文件，如果你自己解析出了这个文件，那么可以把这个文件内容传递给这个方法进行转换，转换后的数据，注意是完整的数据，包含节点树、主题、结构等，可以使用<code>mindMap.setFullData(data)</code>来将返回的数据渲染到画布上</p>
+<p><code>content</code>：<code>.xmind</code>压缩包内的<code>content.json</code>文件内容</p>
+<h3>xmind.transformOldXmind(content)</h3>
+<blockquote>
+<p>v0.2.8+</p>
+</blockquote>
+<p>针对<code>xmind8</code>版本的数据解析，因为该版本的<code>.xmind</code>文件内没有<code>content.json</code>，对应的是<code>content.xml</code>。</p>
