PHP DOM Troubles

[TheJoey]

<?php
$xmlDoc = new DOMDocument();
$xmlDoc->load("abc.xml");
echo '<form method="get">
search: <input type="text" name="search" /><br />
  <input type="submit" value="Submit" />
</form>';

// We need to validate our document before refering to the id
$xmldoc->validateOnParse = true;

function $id
{


}

$xmldoc->getElementByName('$id')->tagName . "\n";
print $xmlDoc->saveXML();
?> 

 

just now sure how to right a function that would search the xml file which contains.

<?php
$xmlDom = new DOMDocument();
$xmlDom->load("searchcontents.xml");


$xmldom->validateOnParse = true;

$variable =$argv[1];

$results =$xmlDom->getElementsByTagname($variable);
if $findresult = $variable
{
foreach ($findresults as $result) {
    // childNodes holds the result values
    $text_nodes = $result->childNodes;

    foreach ($text_nodes as $text) {
         print $text->nodeValue . "\n";
    }
}
}
print $xmlDom->saveXML();
?>
