Question

php part

<?php
    $f = fopen( "temp.xml","r" );
    $str = "";
    while( $line = fgets($f) ){
        if( !($line[1]=='?' || $line[1]=='b' || $line[2]=='b') ){
            $str.= $line."<br>";
        }
    }
    fclose( $f );

    $xdoc = new DomDocument;
    $xdoc->Load('text.xml');
    $body = $xdoc->getElementsByTagName('textBody')->item(0);

    $txtNode = $xdoc ->createTextNode ( $str );
    $body -> appendChild($txtNode);

    $test = $xdoc->save("text.xml");
?>

xml file updated.

<textBody>      
    &lt;br&gt;          
    &lt;br&gt; &amp;#13;
    &lt;br&gt;&lt;font&gt;Heading Here...&lt;/font&gt;&amp;#13;
    &lt;br&gt;&lt;font&gt;Text Here...&lt;/font&gt;&amp;#13;
    &lt;br&gt;
</textBody>



I want to create child in xml file but the special characters are converted into their codes as shown above.
I want the output as

<br><br>
<br><font>Heading Here </font>
<br><font>Text Here</font>
<br>

A textNode contains only character-data.

If you like to create and insert a fragment containing multiple element-nodes use DOMDocument::createDocumentFragment

$xdoc = new DomDocument;
$xdoc->Load('text.xml');
$body = $xdoc->getElementsByTagName('textBody')->item(0);

$fragment = $xdoc ->createDocumentFragment ();
$fragment->appendXML( $str );
$body -> appendChild($fragment);

Please note: appendXML() is not a part of the DOM, it’s a PHP-implementation.

If you like to do it a “clean” DOM-way, create a new document, load the string using loadXML() and import the result into the other document.
