Question

I am using simplexml to load an API URL in the form of an XML through php. In the ProductDescription element it contains html that I would like to append onto in the warranty section.
I would like to add <li>Valid in US</li> in the ProductDescription element before the LAST </ul> tag:

    <xmldata>
      <Products>
        <ProductCode>ACODE</ProductCode>
        <ProductID>1234</ProductID>
        <ProductName>PRODUCTTITLE</ProductName>
        <ProductDescription>
           <h1>Stuff</h1><p>description</p><hr /><strong>Features &amp; Benefits</strong>
           <ul><li>feat</li><li>feat</li><li>feat</li></ul><hr /><strong>Specifications</strong><ul><li>spec</li><li>spec</li><li>spec</li></ul> <hr /><strong>Warranty Information for a certain product</strong>
           <ul><li>3 Years Parts</li><li>3 Years Labor</li></ul><div> <a href="/ahref" target="_blank">See more products from MFG </a></div>
        </ProductDescription>
        <ProductManufacturer>MFG</ProductManufacturer>
      </Products>
    </xmldata>

Now all I can do is get the bare code out of the ProductDescription, I need to know of a way to add that list tag to end of the last ul tag before posting or displaying. Here is my partial php:

     foreach( $xml as $NEW_XML ) 
        {          
            $code = $NEW_XML->ProductCode;
            $name = $NEW_XML->ProductName;
            $desc = $NEW_XML->ProductDescription; 
            $mfg = $NEW_XML->ProductManufacturer;
echo "<textarea rows='13' cols='64' name='DESC' />" . $desc. "</textarea>"; }

I am hoping I dont have to use REGex as it could be a pain (unless someone knows of a way). My inital thoughts would be to put it into a <textarea> and simply posting it back to an xml, but if there is a way to get to save as an .xml directly that would be more effiecient.

Answer 1

If the number of uls is known, you can add the information like this:

$NEW_XML->ProductDescription->ul[2]->addChild('li', 'Valid in US');

This assumes that $NEW_XML is pointing at the Products-Element. To always get the last ul you have to count them first:

$desc = $NEW_XML->ProductDescription;
$count = count($desc->ul);
$desc->ul[$count - 1]->addChild('li', 'Valid in US');

Then you can just output or save $xml->asXML().

Update:

Here is the complete code I used, updated according to my assumption from my last comment, maybe this helps:

<?php
$xmldata = <<<ENDXML
<xmldata>
      <Products>
        <Product>
            <ProductCode>ACODE</ProductCode>
            <ProductID>1234</ProductID>
            <ProductName>PRODUCTTITLE</ProductName>
            <ProductDescription>
               <h1>Stuff</h1><p>description</p><hr /><strong>Features &amp; Benefits</strong>
               <ul><li>feat</li><li>feat</li><li>feat</li></ul><hr />    <strong>Specifications</strong><ul><li>spec</li><li>spec</li><li>spec</li></ul> <hr /><strong>Warranty Information for a certain product</strong>
               <ul><li>3 Years Parts</li><li>3 Years Labor</li></ul><div> <a href="/ahref" target="_blank">See more products from MFG </a></div>
            </ProductDescription>
            <ProductManufacturer>MFG</ProductManufacturer>
        </Product>
        <Product>
            <ProductCode>ANOTHERCODE</ProductCode>
            <ProductID>98765</ProductID>
            <ProductName>PRODUCTTITLE 2</ProductName>
            <ProductDescription>
               <h1>Stuff</h1><p>description</p><hr /><strong>Features &amp; Benefits</strong>
               <ul><li>feat</li><li>feat</li><li>feat</li></ul><hr /> <strong>Specifications</strong><ul><li>spec</li><li>spec</li><li>spec</li></ul> <hr /> <strong>Warranty Information for a certain product</strong>
               <ul><li>3 Years Parts</li><li>3 Years Labor</li></ul><div> <a href="/ahref" target="_blank">See more products from MFG </a></div>
            </ProductDescription>
            <ProductManufacturer>MFG</ProductManufacturer>
        </Product>
    </Products>
</xmldata>
ENDXML;

$xml = simplexml_load_string($xmldata);

foreach ($xml->Products->Product as $product) {
    $description = $product->ProductDescription;
    $count = count($description->ul);
    $description->ul[$count-1]->addChild('li', 'Valid in US');
}

echo $xml->asXML();
