Get words from string - skip html

Question

I use a function to get the first "x" words of a string. Main part is:

preg_match_all('/(<\/?([\w+]+)[^>]*>)?([^<>]*)/', $text, $tags, PREG_SET_ORDER);

When a word is inside html - example:

<a href="/"><u>Linktext</u></a>

The regex see the word "linktext" as a word. Regex should be changed to skip every word that is inside a html tag.

Is this possible?

Use XSL transformations. I used template from related answer ( How to remove all text from an XML document ):

$string = '<a href="/">Some text <u>Linktext</u> more text</a>';
$xslTemplate = '<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                version="1.0">
  <!-- copy all nodes -->
  <xsl:template match="node()">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
  </xsl:template>
  <!-- clear attributes -->
  <xsl:template match="@*">
    <xsl:attribute name="{name()}" />
  </xsl:template>
  <!-- ignore text content of nodex -->
  <xsl:template match="text()" />
</xsl:stylesheet>';

libxml_use_internal_errors(true);

$inputDom = new DOMDocument();
$inputDom->loadHTML($string);

$xslDom = new DOMDocument();
$xslDom->loadXML($xslTemplate);

$cp = new XSLTProcessor();
$cp->registerPHPFunctions();
$cp->importStylesheet($xslDom);

$transformedResult = $cp->transformToDoc($inputDom);
$transformedHtmlString = $transformedResult->saveXML($transformedResult->getElementsByTagName('body')->item(0));

$transformedHtmlString = str_replace('<body>','', $transformedHtmlString); //saveXml() method leaves automatically created body tag
$transformedHtmlString = str_replace('</body>','', $transformedHtmlString);
echo $transformedHtmlString;
