HI i am using ajax for a web site which displays courses available, i am having a problem where i am reading xml(which has courses details) getting node value(course name) comparing to my input(inout course name) if it is equal i am displaying the text(course description). now i am tracing it getting to correct course name(in xml file) but while comparing it to input course name its not at all comparing so.at one point i loaded the xml file and echo it:
$doc->load('data/ICT.xml'); echo"$doc";
It gives me an error
Catchable fatal error: Object of class DOMDocument could not be converted to string in /home/students/....../www/htdocs/client/unit_details.php on line 23
so what i understood from this is that xml dom object should be converted to string so that i can get required data and use it, is it true? if so can some one tell me how to do so please(like any functions etc) thanks in advance :-)
DOMDocument implements the DOM API - access nodes via things like getElementById(), getElementsByClassName() , etc, and use saveXML() to write out a string.
Document convertStringToDocument(String xmlStr) : This method will take input as String and then convert it to DOM Document and return it. We will use InputSource and StringReader for this conversion. String convertDocumentToString(Document doc) : This method will take input as Document and convert it to String.
In this article, you will learn three ways to read XML files as String in Java, first by using FileReader and BufferedReader, second by using DOM parser, and third by using open-source XML library jcabi-xml.
The DOMDocument
object can't be used as a string.
Here is how you would display the DOMDocument
object as an XML string:
echo $doc->saveXML();
DOMDocument
has a method SaveHTML()
, it's designed to do exactly what you need.
You may display whole document by:
$doc->saveHTML();
Or just certain node:
$doc->saveHTML( $bodyNode);
DOMDocument
also provides few options how to enhance how the XML is print, such as:
preserveWhiteSpaces
formatOutput
encoding
