PHP : Function Reference : DOM XML Functions : DomDocument->dump_mem

DomDocument->dump_mem

Dumps the internal XML tree back into a string ()
string DomDocument->dump_mem ( [bool format [, string encoding]] )

Creates an XML document from the dom representation. This function usually is called after building a new dom document from scratch as in the example below. The format specifies whether the output should be neatly formatted, or not.

Example552.Creating a simple HTML document 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("This is the title");
$text = $title->append_child($text);
echo
"<PRE>";
echo
htmlentities($doc->dump_mem(true));
echo
"</PRE>";
?>


Note:

The first parameter was added in PHP 4.3.0.

See also domdocument_dump_file(), and domdocument_html_dump_mem().

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"?>

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.
