From what I can see, it's not really possible - if it was possible, and
you tried to re-read the resulting xml file back, you would end up with
something like:

....
<test>

test

</test>
....

where <bis a child node of the <testnode, rather than part of the
value of the <testnode.

Therefore, entities like < and do need to be encoded / decoded
(possible with html_entity_dec ode()) when dealing with xml.

If, however, you *are* looking to add <bas a child node of <test>, I'm
sure there are functions to handle that ( probably something like $child
= $test->append_child(' b') )

Thank you for the advice,

I'm looking to save HTML inside the XML, for that example that text
may be viewed bold when shown in a browser.

------------------------------------ Test.xml
<?xml version="1.0"?>
<ROOT>
<TEST>
<NAME>TEST PRODUCT 01</NAME>
<DESC>This is a test product, this is bold.</DESC>
<PRICE>9.99</PRICE>
</TEST>
</ROOT>

------------------------------------ Test.xsl
<?xml version="1.0"?>
<xsl:styleshe et version="1.0" xmlns:xsl="http ://www.w3.org/1999/XSL/
Transform">
<xsl:output method="html"/>

<xsl:template match="/">
<html>
<xsl:for-each select="ROOT/TEST">

<hr />
<xsl:value-of select="NAME" / 
<xsl:copy-of select="DESC |text()"/ 
<xsl:value-of select="PRICE" / 
<hr />


</xsl:for-each>

</html>
</xsl:template>
</xsl:stylesheet>

------------------------------------------------------- Test.php
<?php

$xsl = new DomDocument();
$xsl->load("test.xsl ");

$inputdom = new DomDocument();
$inputdom->load("test.xml ");

$proc = new XsltProcessor() ;
$xsl = $proc->importStyleshe et($xsl);

$newdom = $proc->transformToDoc ($inputdom);
print $newdom->saveXML();
?>

----------------------------- Result
<?xml version="1.0" standalone="yes "?>
<html><hr/>TEST PRODUCT 01 

<DESC>This is a test product, this is bold.</DESC>

 9.99 <hr/></html>

-------------------------------- The problem

When a XML document is saved by PHP it looks like

<?xml version="1.0"?>
<ROOT>
<TEST>
<NAME>TEST PRODUCT 01</NAME>
<DESC>This is a test product, this is bold&l t;/b>.</
DESC>
<PRICE>9.99</PRICE>
</TEST>
</ROOT>

I need to be able to save the XML Doc after altering it in PHP:
EX:
$node->nodeValue = "This is a test product, this is bold.";
$dom->save("test.xml ");

without encoding the ""'s.

Re: PHP saving embedded HTML in XML

I have 2 different fixes, one is to a PHP function to swap the chaters
as needed:

function fixXML($string) {

for($i=1; $i < strlen($string) ;$i++) {
$subs1 = substr ($string, $i, 4);

switch ($subs1) {
case ">":
$string = substr ($string, 0, $i) . ">" . substr ($string, $i +4,
strlen($string) );
break;
case "<":
$string = substr ($string, 0, $i) . "<" . substr ($string, $i +4,
strlen($string) );
break;
}
}// end for
return $string;
}

<... code ..>

print fixXML($dom->saveXML());

and another way it can be done in the XSL. I thought this method was
allot messer.... and you would need to call for each charater you need
to swap out.

Snips from test.xsl
--------

<xsl:variable name="myString" select="HEADLIN E" />
<xsl:variable name="myNewStri ng">
<xsl:call-template name="Substring Replace">
<xsl:with-param name="stringIn" select="$myStri ng" />
<xsl:with-param name="substring In" select="'<'"/>
<xsl:with-param name="substring Out" select="'%3C'"/>

</xsl:call-template>
</xsl:variable>
<xsl:value-of select="concat( ' input: ',$myString,' output: ',
$myNewString)" />

<xsl:template name="Substring Replace">
<xsl:param name="stringIn" />
<xsl:param name="substring In" />
<xsl:param name="substring Out" />
<xsl:choose>
<xsl:when test="contains( $stringIn,$subs tringIn)">
<xsl:value-of select="concat( substring-before($stringI n,
$substringIn),$ substringOut)" />
<xsl:call-template name="Substring Replace">
<xsl:with-param name="stringIn" select="substri ng-after($stringIn ,
$substringIn)" />
<xsl:with-param name="substring In" select="$substr ingIn" />
<xsl:with-param name="substring Out" select="$substr ingOut" />
</xsl:call-template>
</xsl:when>
<xsl:otherwis e>
<xsl:value-of select="$string In" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>

I hope this helps someone.

good luck

Hi

You can do it like Ian said:

$elem = $dom->createElement( 'b');
$elem->nodeValue = 'test';
$test->appendChild($e lem);

Or using a document fragment

$fragment = $dom->createDocument Fragment();
$fragment->appendXml(' test');
$test->appendChild($f ragment);
