Hello, this is my first posting and first patch proposal, so please be
kind. :) (This message might occur more then once, i dont seem to get
friends with the list server)
I recognized at work today that DOMDocument has two function saveHTML and
saveHTMLFile, but only a save function for the "unfiltered" xml node
structure to save to a file although libxml
provides the functionality to export the data to string.
This is bad because saveHTML(File) does lots of filtering on the output and
if the document still has internal placeholders inside because its not
finished they won't be recognized again. save() circumvents this by just
printing the original inputted data, but needs to be used by saving the
data into a tmp file and extracting it back by using file_get_contents for
example.
I created a patch that adds a new method "DOMDocument::ouput" that does
what save() does just returns the output as a string from the function. I
have attached the two diffs, they go in "ext/dom/" I tested this with
5.2.6. They are essentially copy paste and merge of the DOMDocument::save
and DOMDocument::saveHtml functions. I changed the PHP.net manual snippet
as a demo:
<?php
$doc = new DOMDocument('1.0');
$root = $doc->createElement('html');
$root = $doc->appendChild($root);
$head = $doc->createElement('head');
$head = $root->appendChild($head);
$title = $doc->createElement('title');
$title = $head->appendChild($title);
$text = $doc->createTextNode('This is the title');
$text = $title->appendChild($text);
echo $doc->output();
?>
