Proprietăți

wholeText: Holds all the text of logically-adjacent (not separated by Element, Comment or Processing Instruction) Text nodes.

Cuprins

DOMText::__construct — Creates a new DOMText object
DOMText::isElementContentWhitespace — Returns whether this text node contains whitespace in element content
DOMText::isWhitespaceInElementContent — Indicates whether this text node contains whitespace
DOMText::splitText — Breaks this node into two nodes at the specified offset

Text replacement function for DOM.

<?php
function domTextReplace( $search, $replace, DOMNode &$domNode, $isRegEx = false ) {
  if ( $domNode->hasChildNodes() ) {
    $children = array();
    // since looping through a DOM being modified is a bad idea we prepare an array:
    foreach ( $domNode->childNodes as $child ) {
      $children[] = $child;
    }
    foreach ( $children as $child ) {
      if ( $child->nodeType === XML_TEXT_NODE ) {
        $oldText = $child->wholeText;
        if ( $isRegEx ) {
          $newText = preg_replace( $search, $replace, $oldText );
        } else {
          $newText = str_replace( $search, $replace, $oldText );
        }
        $newTextNode = $domNode->ownerDocument->createTextNode( $newText );
        $domNode->replaceChild( $newTextNode, $child );
      } else {
        domTextReplace( $search, $replace, $child, $isRegEx );
      }
    }
  }
}
