I want to be able to create a XML File, add nodes and such to it, then output it to the screen without saving.
$bookxml = new DOMDocument('1.0', 'utf-8');
is how i have the XML file created, however i just can't anyway to display the XML file on the screen without saving it.
However i am having a problem with outputting even in save, this is the line i have
echo $bookxml->save("testing.xml");
All this does is return the file size of the newly created XML, and not the contents.
Any help would be awesome, i'm completely stumped on this.
What you're looking for is saveXML, additionally you can use htmlspecialchars to encode the xml so you can see it in your browser display.
echo htmlspecialchars($bookxml->saveXML());
You want the saveXML method, not the save method:

Currently I have a PHP file that reads posted XML and then converts/outputs it to JSON. This file looks like this:
<?php
file_put_contents('myxmlfile.xml', file_get_contents('php://input'));
$xmldoc = new DOMDocument();
$xmldoc->load("myxmlfile.xml");
$xpathvar = new DOMXPath($xmldoc);
// Etc etc, for the purpose of my question seeing the rest isn't necessary
// After finishing the conversion I save the file as a JSON file.
file_put_contents('myjsonfile.json', $JSONContent);
?>
The data I'm receiving comes in XML format. To convert it I'm currently saving it as an XML file, and then immediately after creating a new DOMDocument() and loading it in. My question is, is there any way I can cut out the middle man and just load in the XML directly using file_get_contents()?
Ideally it would be this (didn't work):
$xmldoc->load(file_get_contents("php://input"));
If anyone could help me do this I'd really appreciate it!
Thanks
To load from string, instead of filename, use loadXML method.
$xmldoc->loadXML(file_get_contents("php://input"));
<?php
$xmlDoc = new DOMDocument();
$xmlDoc->load("note.xml");
print $xmlDoc->saveXML();
?>
In the above code sample I don't understand the last line. why we use saveXML(). Is there anyway to print the xml file without using saveXML(). Please anyone can answer my questions.
If you are loading the xml from a file and you are not modifying it in any way, there's no need to call saveXML(). saveXML is mostly used when you create an xml document from scratch.
If you only want to check the contents of the file, you could use file_get_contents, instead of using DomDocument. DomDocument is more useful when you want to make changes or parse.
I'm trying to archive a web base forum that has attachments that users have posted. So far, I made use of the php cURL library to get the individual topics and have been able to save the raw pages. However, I now need to figure out a way to archive the attachments that are located on the site.
Here is the problem: Since the file type is not consistent, I need to find a way to save the files with the correct extension. Note that I plan to rename the file when I save it so that it's organized in a way that it can be easily found later.
The link to the attached files in a page is in the format:
some file.txt
I've already used preg_match() to get the URL's to the attached files. My biggest problem now is now just making sure the fetched file is saved in the correct format.
My question: Is there any way to get the file type efficiently? I'd rather not have to use a regular expression, but I'm not seeing any other way.
Does the server add the correct Content-Type header field when serving the files? You can then intercept that with setting CURLOPT_HEADER or file_get_contents + $http_response_header.
http://www.php.net/manual/en/reserved.variables.httpresponseheader.php
i would look into
http://www.php.net/manual/en/book.fileinfo.php
to see if you can automatically grab the file type when you get ahold of it.
you can use DOMDocument and DOMXpath to extract urls and filename safely.
$doc=new DOMDocument();
$doc->loadHTML($content);
$xpath= new DOMXpath($doc);
//query examples:
foreach($xpath->query('//a') as $node)
echo $node->nodeValue;
foreach($xpath->query('//a/#href') as $node)
echo $node->nodeValue;
may be i am going to ask some stupid question but i don't have any idea about php
that's why i want to know it i never worked in php and now i have to do it so please provide me some useful tips,
i have XML file that is coming from a different URL and i want to save it on the server then i have to read it and extract it to a page in proper format and some modification in data.
You can use DOM
$dom = new DOMDocument();
$dom->load('http://www.example.com');
This would load the XML from the remote URL. You can then process it as needed. See my previous answers on various topics using DOM. To save the file to your server after your processed it, you use
$dom->save('filename.xml');
Loading the file with $dom->load() will only work if you have allow_url_fopen enabled in your php.ini. If not, you have to use cURL to download the remote file first.
Maybe this should be helpfull to you: http://www.php.net/manual/en/function.simplexml-load-file.php
If you're have dificulte to get the XML file from the remote host you can use combine with above simplexml-load-string
$path_to_xml = 'http://some.com/file.xml';
$xml = simplexml_load_string( file_get_content($path_to_xml) );
I need to generate an editable xml file to supply content to a flash website.
I am generating my file with a html form, and htmlspecialchars e.g.:
$currentItem = htmlspecialchars(stripslashes($currentItem));
This is to prevent xml entries which would produce the error "XML Parsing Error: not well-formed", such as
<entry title="Words & Things">
---------------------^
It has the side effect of making the flash file display the html codes for the content, rather than the proper characters.
Is there a good way to convert the codes back, once they are read into the Flash file (as3)?
Maybe try:
public function htmlUnescape(str:String):String
{
return new XMLDocument(str).firstChild.nodeValue;
}

Use html_entity_decode: http://us.php.net/manual/en/function.html-entity-decode.php
