Re: Replacing text of a DOM text node

Hello Rob. Thank you very much indeed! Since this DOM thing is very new to me (well, maybe not the DOM concept but working with DOM function in PHP), I appreciate especially the links you provided. Right now I am able to loop through all text nodes, replace certain characters and mark a column for translation so to say. And this is pretty much everything I needed to know in order to go on. One problem I definitely see coming up will be dealing with headers that have attributes like colspan or rowspan. But that's another story. /frank 7 jun 2006 kl. 12.26 skrev Rob Richards:

Hi Frank, Frank Arensmeier wrote: Jochem, thank you for your input! So, right now I am able to access all text nodes by e.g. $nodeElement -> parentNode -> childNodes -> item(0); -> returns Lenght, Width and so on $nodeElement -> parentNode -> childNodes -> item(1); -> is empty $nodeElement -> parentNode -> childNodes -> item(2); -> returns mm, kg ... and so on. Or is there an easier way? When trying to acces the items by ($nodeElement containing text nodes) $nodeElemtent -> item(0); I get the following error message: Call to undefined method DOMText::item()... Only a nodelist and namenodemap has the item() method. You could also do something like the following - note that manually walking the tree is much faster than iterating a nodelist - (there are also many different variations of this code depending upon what you need to do with the subtree): $node = $nodeElement->parentNode->firstChild; while ($node) { /* only process text or element nodes here */ if ($node->nodeType == XML_TEXT_NODE) {

      $node->nodeValue = 'New text content'; /* modify text content */

} else if ($node->nodeType == XML_ELEMENT_NODE) {

      /* node is element - process its subtree or move on i.e.: */
      if ($node->hasChildNodes()) {
         foreach ($node->childNodes AS $child) {
            /* process child nodes here */
         }
      }

} $node = $node->nextSibling; } BTW, is there an easy way to get the total amount of items in a curent node? count ( $nodeElement -> parentNode -> childNodes ) always returns 1. For now the only solution I know of is looping through the nodeElements (e.g. foreach ( $nodeElement as $value ) and have a counter inside the loop. $count = $nodeElement->parentNode->childNodes->length; This property is only available from a nodelist or namednodemap. Thank you so far. /frank ps. I am desperately looking for some good sites covering the PHP DOM functions. On www.php.net/dom there are barely some examples. And on www.zend.com I only found one article with very, very basic examples. Any ideas/suggestions are more than welcome. ds. You can pretty much search for examples from any DOM implementation since its a standard (not too difficult to go from one language to another when using DOM). For PHP specific ones, there are a number of tests in the CVS repository that demonstrate much of the functionality: http://cvs.php.net/viewcvs.cgi/php-src/ext/dom/tests/ One particular test that uses a good amount of the API (though the basic functions) is dom001.phpt: http://cvs.php.net/viewcvs.cgi/php-src/ext/dom/tests/dom001.phpt?view=markup&rev=1.4 Rob --rrichards@ctindustries.net author of Pro PHP XML and Web Services from Apress --PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
