php export xml CDATA escaped -


i trying export xml cdata tags. use following code:

$xml_product = $xml_products->addchild('product'); $xml_product->addchild('mychild', htmlentities("<![cdata[" . $mytext . "]]>"));

the problem cdata tags < , > escaped &lt; , &gt; following:

 <mychild>&lt;![cdata[my long long long text]]&gt;</mychild>

but need:

<mychild><![cdata[my long long long text]]></mychild>

if use htmlentities() lots of errors tag raquo not defined etc... though there no such tags in text. htmlentities() tries parse text inside cdata , convert it, dont want either.

any ideas how fix that? thank you.

upd_1 function saves xml file:

public static function saveformattedxmlfile($simplexmlelement, $output_file) {     $dom = new domdocument('1.0', 'utf-8');     $dom->preservewhitespace = false;     $dom->formatoutput = true;     $dom->loadxml(urldecode($simplexmlelement->asxml()));     $dom->save($output_file);  }

a short example of how add cdata section, note way skips using domdocument add cdata section in. code builds <product> element, $xml_product has new element <mychild> created in it. newnode imported domelement using dom_import_simplexml. uses domdocument createcdatasection method create appropriate bit , adds node.

$xml = new simplexmlelement('<?xml version="1.0" encoding="utf-8"?><products />');  $xml_product = $xml->addchild('product'); $newnode = $xml_product->addchild('mychild'); $mytext = "<html></html>"; $node = dom_import_simplexml($newnode); $cdata = $node->ownerdocument->createcdatasection($mytext); $node->appendchild($cdata); echo $xml->asxml();

this example outputs...

<?xml version="1.0" encoding="utf-8"?> <products><product><mychild><![cdata[<html></html>]]></mychild></product></products>

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
