DomDocument->dump_mem — Schreibt den internen XML-Baum in eine Zeichenkette
Generiert ein XML-Dokument aus der DOM-Repräsentation. Diese Funktion wird normalerweise aufgerufen, nachdem ein neues DOM-Dokument generiert wurde. Der Parameter format gibt an, ob die Ausgabe sauber formatiert erfolgen soll.
Beispiel #1 Generiere einen HTML-Header
<?php
$doc = domxml_new_doc("1.0");
$root = $doc->create_element("HTML");
$root = $doc->append_child($root);
$head = $doc->create_element("HEAD");
$head = $root->append_child($head);
$title = $doc->create_element("TITLE");
$title = $head->append_child($title);
$text = $doc->create_text_node("Das ist der Titel");
$text = $title->append_child($text);
echo "<PRE>";
echo htmlentities($doc->dump_mem(true));
echo "</PRE>";
?>
Hinweis:
Der erste Parameter wurde in PHP 4.3.0 hinzugefügt.
Siehe auch domdocument_dump_file() und domdocument_html_dump_mem().
It seems that if you use $xslt->dump_mem(TRUE) IE: breaks and formats all the HTML Badly. Perhaps its a problem with CR's...
Given the missing description of the encoding parameter, I had hoped it would automatically encode the document if I set the encoding type; this is not the case.
At least in PHP v4.3.3, it seems that setting the encoding type does NOTHING other than set the name displayed in the string:
<?xml version="1.0" encoding="UTF-8"?>
Thus if you want your values to be encoded, you need to manually encode them when you create your DOM object. E.g. assume you have a simple setup like this:
<?php
$text = '¡Spanish exclamation!' ;
$xml = domxml_new_doc( '1.0' );
$node = $xml->create_element( 'example' );
$cdata = $xml->create_cdata_section( $text );
$node->append_child( $cdata );
$xml->append_child( $node );
echo $xml->dump_mem( true, 'UTF-8' ) ;
?>
This will output the following:
<?xml version="1.0" encoding="UTF-8"?>
<example>
<![CDATA[¡Spanish exclamation!]]>
</example>
However, that is not what was intended, as the exclamation is not UTF-8-encoded. To make $text be encoded correctly, you have to explicitly do so, as in:
<?php
$cdata = $xml->create_cdata_section( utf8_encode( $text ) );
?>
This results in the output being correctly UTF-8-encoded, as follows:
<![CDATA[¡Spanish exclamation!]]>
Apparently MSIE's MSXML2.DOMDocument ActiveX control requires UTF-8 encoding for special characters, and it will invalidate the entire document if those chars are not appropriately encoded, so beware.
<pre>
for xml file that goes like this:
<item>
<name>foo</name>
<desc>bar</desc>
</item>
Format ID's influence output in this manner:
case 0 :{
<item><name>foo</name><desc>bar</desc></item>
}
case 1 :{
<item>
<name>foo</name>
<desc>bar</desc>
</item>
}
case 2:{
<item>
<name>
foo
</name>
<desc>
bar
</desc>
</item>
If you use PHP SAX(Expat) XML engine, you should always stick to format "0". It reads any empty spaces as XML data.
</pre>
string dump_mem(int format, string encoding);
format=0,1 = <tag>text</tag>
format=2 =
<tag>
text
</tag>
encoding set's the encoding attribute in line
<?xml version="1.0" encoding="iso-8859-1"?>
