属性

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

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 );

      }

    }
