如何使用正则表达式将多个空白字符替换为无?例如:
<div class="someClass" id="someID">
...bunch of elements/content
<input type="button" name="myInput" id="inputID" title="myInput Title" />
...bunch of elements/content
</div>
替换后:
<a class="myselector" rel="I need this value"></a><div class="someClass" id="someID">...bunch of elements/content<input type="button" name="myInput" id="inputID" title="myInput Title" />...bunch of elements/content</div>
