* This is a hack that overcomes the issue of node shifting when scanning and removing nodes.

* In the JS version of getElementsByTagName, if you remove a node it will not appear during the
* foreach. This does not happen in PHP DOMDocument, because if you remove a node, it will still appear but as an
* orphan node and will give an exception if you try to do anything with it.
*
* Shifting also occurs when converting parent nodes (like a P to a DIV), which in that case the found nodes are
* removed from the foreach "pool" but the internal index of the foreach is not aware and skips over nodes that
* never looped over. (index is at position 5, 2 nodes are removed, next one should be node 3, but the foreach tries
* to access node 6)
*
* This function solves this by searching for the nodes on every loop and keeping track of the count differences.
* Because on every loop we call getElementsByTagName again, this could cause a performance impact and should be
* used only when the results of the search are going to be used to remove the nodes.
