<h3>详细</h3>
|
||
<p>在XML和对象之间进行转换时，默认情况下XML属性会添加到名为<code>$</code>的属性中。将文本内容添加到名为<code>_</code>的属性中。这些属性名称可以在节点设置中更改。</p>
|
||
<p>例如，将如下所示转换以下XML：</p>
|
||
<pre><p class="tag">Hello World</p></pre>
|
||
<pre>{
|
||
"p": {
|
||
"$": {
|
||
"class": "tag"
|
||
},
|
||
"_": "Hello World"
|
||
}
|
||
}</pre>
|
||
</script>
