PHP creating xml from a long xslt form - Need some guidance / anything

[unvoid]

I want to be able to this: http://www.w3schools.com/Xsl/xsl_editxml.asp but with php

 

so far I have been able to create the form with xslt using php but I have not figured out how to save all the newly inputted data into the xml.

 

Here is what I have:

 

a snippet of my xslt (which is a monster of a file):

<table class="load" cellpadding="0" cellspacing="0" border="1" bordercolor="#000000" width="100%" bgcolor="#A5AC9D" style="text-align:center;">
<thead>
<th style="color:#0a63a7; width:22%;">Group</th>
<th style="color:#0a63a7; width:28%;">Field</th>
<th style="color:#0a63a7; width:39%;">New Value</th>
</thead>

<xsl:for-each select="TEST_CONFIGURATION/TEST_HARNESS_HOST/NAME">
<tr>
<td>TEST_HARNESS_HOST</td>
<td>NAME</td>
<td class="col3"><input type="text" style="width:100%;" name="TEST_CONFIGURATION/TEST_HARNESS_HOST/NAME">
<xsl:attribute name="id">
  <xsl:value-of select="." />
</xsl:attribute>
<xsl:attribute name="value">
  <xsl:value-of select="." />
</xsl:attribute>
</input> 
</td>
</tr>
</xsl:for-each>

<xsl:for-each select="TEST_CONFIGURATION/TEST_HARNESS_HOST/IP_ADDRESS">
<tr><td></td>
<td>IP_ADDRESS</td>
<td class="col3"><input type="text" style="width:100%;" name="TEST_CONFIGURATION/TEST_HARNESS_HOST/IP_ADDRESS">
<xsl:attribute name="id">
  <xsl:value-of select="." />
</xsl:attribute>
<xsl:attribute name="value">
  <xsl:value-of select="." />
</xsl:attribute>
</input> 
</td>
</tr>
</xsl:for-each>


<!-- Host 1 -->
<xsl:for-each select="TEST_CONFIGURATION/HOST[@RefName='HOST_1']/NAME">
<tr><td>HOST_1</td>
<td>NAME</td>
<td class="col3"><input type="text" style="width:100%;" name="TEST_CONFIGURATION/HOST[@RefName='HOST_1']/NAME" >
<xsl:attribute name="id">
  <xsl:value-of select="." />
</xsl:attribute>
<xsl:attribute name="value">
  <xsl:value-of select="." />
</xsl:attribute>
</input> 
</td>
</tr>
</xsl:for-each>

 

my php so far (this loads the xml and creates the form that I want):

//Reads users custom built xmldoc file to create the editable fields
            $rfile = $xmldoc;
            $freader = fopen($rfile, 'r') or die("Can't open read file");
            $theData = fread($freader, filesize($rfile));
            fclose($freader);
            
            // Load XML file
            $XML = new DOMDocument();
            $XML->loadXML( $theData );
            
            // Start xslt
            $xslt = new XSLTProcessor();
            $XSL = new DOMDocument();
            $XSL->load( $XSLpath, LIBXML_NOCDATA);
            $xslt->importStylesheet( $XSL );
            
            // Print 
            print $xslt->transformToXML( $XML ); 

 

The end goal is to allow a user to load up an xml doc using the xslt to create a form that allows them to change any of the fields in their xml document.

 

Here is what I have been trying so far for the update function but with no success (I have ??? where I think I am on to something but I am not really sure where to go with it since I need to edit so many different random fields that the user changes):

$dom = new DOMDocument();  
$dom->load($eid);  
$xpath = new DOMXPath($dom);  
   
$values = $xpath->query('????');  
foreach($values as $value)  
{  
    $a = $value->nodeValue; // shortcut  
    $currentEntry  = substr($a);  
    $userEntry = _POST[??];  
    $value->nodeValue = "{$userEntry}";  
}  
  
$dom->save($eid);
