Description:
------------
DOMText->splitText() does not split text nodes correctly.  The node returned from the splitText() includes text from additional DOMText nodes following the one being split.  Instead, the returned node should only containg text that was in the original node, following the split offset.

Here is a html version of the reproduce code, along with some javascript to demonstrate the splitText() method:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-15">
</head>

<body>
<p id="p" onclick="splitText(this)">text1<i>i</i>text2</p>

<script type="text/javascript">
function splitText(node) {
  text1 = node.firstChild;
  split = text1.splitText(2);
  text2 = node.lastChild;
  str = 'text1:  ' + text1.nodeValue + '\n' +
        'split:  ' + split.nodeValue + '\n' +
        'text2:  ' + text2.nodeValue;
  alert(str);
}
</script>
</body></html>


It turns out the fix for this is a 1-liner in ext/dom/text.c.  I've created a diff available here:
http://www.digitaljunkies.ca/~benj/text.c.diff



Reproduce code:
---------------
#!/usr/bin/php
<?php

$xml = new DomDocument();

$p = $xml->createElement("p");
$p->insertBefore($text1 = $xml->createTextNode("text1"));
$p->insertBefore($i = $xml->createElement("i"));
$i->insertBefore($itext = $xml->createTextNode("i"));
$p->insertBefore($text2 = $xml->createTextNode("text2"));

$split = $text1->splitText(2);

echo ("text1:  " . $text1->nodeValue . "\n");
echo ("split:  " . $split->nodeValue . "\n");
echo ("text2:  " . $text2->nodeValue ."\n");

?>

Expected result:
----------------
text1:  te
split:  xt1
text2:  text2


Actual result:
--------------
text1:  te
split:  xt1text2
text2:  text2
