如何使用正则表达式删除这些标记之间的换行符？

我确实在SO上看到了另一个解决方案，但它使整个文件没有新的行。我只需要一个没有新行的特定部分。
我正在尝试删除这些标签之间的间距，使它们恰好相邻，如下所示：
<a rel="nofollow noopener" style="display:inline; text-decoration: none;" href=""><img border="0" class="full" height="auto" width="300" alt="" src="http://via.placeholder.com/600x338"></a><a rel="nofollow noopener" style="display:inline; text-decoration: none;" href=""><img border="0" class="full" height="auto" width="300" alt="" src="http://via.placeholder.com/600x338"></a><a rel="nofollow noopener" style="display:inline; text-decoration: none;" href=""><img border="0" class="full" height="auto" width="300" alt="" src="http://via.placeholder.com/600x338"></a><a rel="nofollow noopener" style="display:inline; text-decoration: none;" href=""><img border="0" class="full" height="auto" width="300" alt="" src="http://via.placeholder.com/600x338"></a>它们目前看起来是这样的：
<a rel="nofollow noopener" style="display:inline; text-decoration: none;" href="">
<img border="0" class="full" height="auto" width="300" alt="" src="http://via.placeholder.com/600x338">
</a>
<a rel="nofollow noopener" style="display:inline; text-decoration: none;" href="">

下面是我在注释中添加的建议正则表达式的示例，我添加了\t & \s{2,}来提取制表符和2个或更多空格字符。
let temp = `<a rel="nofollow noopener" style="display:inline; text-decoration: none;" href="">
<img border="0" class="full" height="auto" width="300" alt="" src="http://via.placeholder.com/600x338">
</a>
<a rel="nofollow noopener" style="display:inline; text-decoration: none;" href="">
<img border="0" class="full" height="auto" width="300" alt="" src="http://via.placeholder.com/600x338">
</a>
<a rel="nofollow noopener" style="display:inline; text-decoration: none;" href="">
<img border="0" class="full" height="auto" width="300" alt="" src="http://via.placeholder.com/600x338">
</a>
<a rel="nofollow noopener" style="display:inline; text-decoration: none;" href="">
<img border="0" class="full" height="auto" width="300" alt="" src="http://via.placeholder.com/600x338">
</a>`;
console.log(temp.replace(/[\r\n|\r|\n|\t]/g, '').replace(/\s{2,}/g, ' '))

此模式应该有效：(?<=>)\s*|\s*(?=<a)
您可以看到一个演示here。只需将匹配项替换为""
