Javascript以空格分隔，但不在html标签内

Question

My first goal is to split a string by spaces, but not the ones within html-tags.

I've tried to rewrite the following, unsuccessfully: Javascript split by spaces but not those in quotes

What would the regex look like in: arr = fullHtmlString.split( ? ); ?

My main goal is to shift an IMG-tag by one space at a time. After that I'll iterate over the array, search for the img-tag, remove it, and add it the next item, and finally join the array.

The code I use at the moment is quite comprehensive and use jQuery extensively to achive the goal.

Input:

<div>
    <p><img class=something>Some text.</p>
    <p>Some more text.</p>
</div>

Deisred output first time:

<div>
    <p>Some<img class=something> text.</p>
    <p>Some more text.</p>
</div>

...second time:

<div>
    <p>Some text.<img class=something></p>
    <p>Some more text.</p>
</div>

...third time:

<div>
    <p>Some text.</p>
    <p><img class=something>Some more text.</p>
</div>

You should not try to do this with a regular expression, why explained here .

You can use DOM properties and methods though

 function run(){ var img = document.querySelector(".something"), sibling = img, parent = img.parentNode, next = parent.nextElementSibling; //Search for the next textNode while((sibling = sibling.nextSibling) && sibling.nodeType !=3); if(sibling) { //split the text only once, //so "some more text" becomes ["some","more text"] var textParts = sibling.textContent.split(/ (.*)?/,2); //put the first split item before the sibling parent.insertBefore(document.createTextNode(textParts[0]+" "),sibling); //replace the sibling with the img element parent.replaceChild(img,sibling); //finally if there was more text insert it after the img textParts[1] && parent.insertBefore(document.createTextNode(textParts[1]),img.nextSibling); } else if(!sibling && next) { //no sibling in the current parent, //so prepend it to the next available element in parent next.insertBefore(img,next.firstChild); } else { clearInterval(timer); } } var timer = setInterval(run,2000); 

 <div> <p><img class="something" src="http://placehold.it/10x10">Some text.</p> <p>Some <span>skip me</span> more text.</p> </div>
