如何创建一个不迭代 1 而是迭代 n 的循环？
在此示例中，我如何读取五行，然后下一次迭代读取其他五行，依此类推？
example = '<div id="post-editor" class="post-editor">
<div class="wmd-container">
<div id="wmd-button-bar" class="wmd-button-bar"></div>
<textarea id="wmd-input" class="wmd-input" name="post-text" cols="92" rows="15" tabindex="101"></textarea>
</div>
<div class="fl" style="margin-top: 8px; height:24px;"> </div>
<div id="draft-saved" class="draft-saved community-option fl" style="margin-top: 8px; height:24px; display:none;">draft saved</div>
<div id="draft-discarded" class="draft-discarded community-option fl" style="margin-top: 8px; height:24px; display:none;">draft discarded</div>
<div id="wmd-preview" class="wmd-preview"></div>
<div></div>
<div class="edit-block">
<input id="fkey" name="fkey" type="hidden" value="7668dcce69f925d656bc4019c29fd061">
<input id="author" name="author" type="text">
</div>
</div>'

最佳答案
你可以这样做:
example.each_line.each_slice(5) { |lines| # do something with lines }
