Get tag value from XML using PHP

[pbvamsi]

My XML file looks like

<entry>
    some tags 
    <title type='text'> content to be extracted </title>
    <content type='text'> content to be extracted </content>
    </entry>

(there will be 3-4 titles and descriptions in each entry tag, bt i want only whose type is text) i used

$dom = new DOMDocument();
libxml_use_internal_errors(true);
$dom->loadXML("kFeed.xml");
$entryTag = $dom->getElementsByTagName("entry")->item(0);
$title = $entryTag->getElementsByTagName("title")->item(0)->nodeValue;
$descr = $entryTag->getElementsByTagName("content")->item(0)->nodeValue;

the error i get is

Fatal error: Call to a member function getElementsByTagName() on a non-object 

can someone help me to fix this problem. thanks

item(0) is a textNode and those don't have the same methods as other nodes. getElementsByTagName is one, simply due to the fact that textNodes can't have childNodes. Thus, it does not have the childNodes property either.

There are no tags for text nodes, but if there was, your xml would look like this

<entry><#text>
    some tags 
    </#text><title type='text'> content to be extracted </title><#text>
    </#text><content type='text'> content to be extracted </content><#text>
    </#text></entry>
