/* Properties */

readonly public string $wholeText ;

/* Methods */

public __construct ([ string $value ] )

public bool isWhitespaceInElementContent ( void )

public DOMText splitText ( int $offset )

/* Inherited methods */

public DOMNode DOMNode::appendChild ( DOMNode $newnode )

public string DOMNode::C14N ([ bool $exclusive [, bool $with_comments [, array $xpath [, array $ns_prefixes ]]]] )

public int DOMNode::C14NFile ( string $uri [, bool $exclusive [, bool $with_comments [, array $xpath [, array $ns_prefixes ]]]] )

public DOMNode DOMNode::cloneNode ([ bool $deep ] )

public int DOMNode::getLineNo ( void )

public string DOMNode::getNodePath ( void )

public bool DOMNode::hasAttributes ( void )

public bool DOMNode::hasChildNodes ( void )

public DOMNode DOMNode::insertBefore ( DOMNode $newnode [, DOMNode $refnode ] )

public bool DOMNode::isDefaultNamespace ( string $namespaceURI )

public bool DOMNode::isSameNode ( DOMNode $node )

public bool DOMNode::isSupported ( string $feature , string $version )

public string DOMNode::lookupNamespaceURI ( string $prefix )

public string DOMNode::lookupPrefix ( string $namespaceURI )

public void DOMNode::normalize ( void )

public DOMNode DOMNode::removeChild ( DOMNode $oldnode )

public DOMNode DOMNode::replaceChild ( DOMNode $newnode , DOMNode $oldnode )

}

Properties

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::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 );

      }

    }

  }

}
