I'm working on some system for a few hours now and this little thing is too much for me to think logically about at the moment.
Normally I would wait a few hours but this is a last minute job and I need to finish this.
Here's my problem:
I have an XML file that gets posted to my PHP file, the PHP file inserts certain data into a DB, but some XML nodes have the same name:
<accessoires>
<accessoire>value1</accessoire>
<accessoire>value2</accessoire>
<accessoire>value3</accessoire>
</accessoires>
Now I want to get a var $acclist which contains all values seperated by a comma:
value1,value2,value3,
I bet the solution to this is very easy but I'm at the known point where even the easiest piece of code becomes a hassle. And googling only comes up with nodes that in some way have their own identifiers.
Could someone help me out please?
You can try simplexml_load_string to parse the html then call implode on the node after casting to an array.
NOTE This code was tested in php 5.4.6 and behaves as expected.
<?php
$xml = '<accessoires>
<accessoire>value1</accessoire>
<accessoire>value2</accessoire>
<accessoire>value3</accessoire>
</accessoires>';
$dat = simplexml_load_string($xml);
echo implode(",",(array)$dat->accessoire);
For 5.3.x I had to change to
$xml = '<accessoires>
<accessoire>value1</accessoire>
<accessoire>value2</accessoire>
<accessoire>value3</accessoire>
</accessoires>';
$dat = simplexml_load_string($xml);
$dat = (array)$dat;
echo implode(",",$dat["accessoire"]);
You do this by taking a library that is able to parse and process XML, for example with SimpleXML:
implode(',', iterator_to_array($accessoires->accessoire, FALSE));
The key part here is to use iterator_to_array() as SimpleXML offers the same-named child-elements here as an iterator. Otherwise $accessoires->accessoire gives you auto-magically only the first element (if any).

I'm having some trouble parsing malformed XML in PHP. In particular I'm querying a third party webservice that returns data in an XML format without encoding the XML entities in actual data. For example one of the the elements contains an ASCII heart, '<3', without the quotes, which the XML parser sees as an opening tag. It should be '<3'.
Right now I'm simply passing the XML string into a SimpleXMLElement which, predictably, fails on these instances. I've done some looking around and it seems like PHP Tidy package might be able to help me, but the amount of configuration you can do is overwhelming :(
Thus, I'm just wondering if anyone else has had a problem like this and, if so, how they were able to solve it.
Thanks!
Try tidy.repairString:
php > $tidy = new tidy();
php > $repaired = $tidy->repairString("<foo>I <3 Philadelphia</foo>", array("input-xml"=>1));
php > print($repaired);
<foo>I <3 Philadelphia</foo>
php > $el = new SimpleXMLElement($repaired);
Read the content as a string.
htmlspecialchars(preg_replace('/[\x-\x8\xb-\xc\xe-\x1f]/','',$string))
Load the transformed string in SimpleXMLElement
It worked for me so far.
I need help to extract value from a soap response.
https://i.stack.imgur.com/djv5y.jpg
What i exactly need is:
$username=user
$message=success
Maybe include the SOAP response here, that would be helpful for those who come in the future. As for your question are you using a particular language? That would make it easier to answer.
If you are looking for a way to view use can use this URL: https://codebeautify.org/xmlviewer
Ok now that I see it, it's fairly easy
Assuming you have loaded the SOAP XML into a variable, lets call it $xml_string
$xml = simplexml_load_string($xml_string); // Load it as an object
$xmlarray = json_decode(json_encode($xml),TRUE); // Change it into an array
Then the variables you are looking for is in
$username = $xmlarray['UserName'];
$message = $xmlarray['response']['MESSAGE'];
BTW This solution is found here
PHP convert XML to JSON
I did it as an array as sometimes objects are a little hard to process. You can easily just do the first line and address it as an object. (If those are the only variables you need then an array works fine. Ex: the 'Plan' data will be messed up in an array as it appears twice)
There can be some issues such as the MESSAGE not appearing or the XML returning a failure but I think you should know how to code around missing datum.
I have two lines of XML data that are attributes but also contain data inside then and they are repeating fields. They are being stored in a SimpleXML variable.
<inputField Type="Name">John Doe</inputField>
<inputField Type="DateOfHire">Tomorrow</inputField>
(Clearly this isnt real data but the syntax is actually in my data and I'm just using string data in them)
Everything that I've seen says to access the data like this, ,which I have tried and it worked perfectly. But my data is dynamic so the data isn't always going to be in the same place, so it doesn't fit my needs.
$xmlFile->inputField[0];
$xmlFile->inputField[1];
This works fine until one of the lines is missing, and I can have anywhere from 0 to 5 lines. So what I was wondering was is there any way that I can access the data by attribute name? So potentially like this.
$xmlFile->inputField['Name'];
or
$xmlFile->inputField->Name;
I use these as examples strictly to illustrate what I'm trying to do, I am aware that neither of the above lines of code are syntactically correct.
Just a note this information is being generated externally so I cannot change the format.
If anyone needs clarification feel free to let me know and would be happy to elaborate.
Maybe like this?
echo $xmlFile->inputField->attributest()->Name;
And what you're using? DOMDocument or simplexml?
You don't say, but I assume you're using SimpleXMLElement?
If you want to access every item, just iterate:
foreach ($xmlFile->inputField as $inputField) { ... }
If you want to access an attribute use array notation:
$inputField['Type']
If you want to access only one specific element, use xpath:
$xmlFile->xpath('inputField[#Type="Name"]');
Perhaps you should read through the basic examples of usage in the SimpleXMLElement documentation?
For example you can a grab a data:
$xmlFile = simplexml_load_file($file);
foreach($xmlFile->inputField as $res) {
echo $res["Name"];
}
What I've been trying to do recently is to extract listing information from a given html file,
For example, I have an html page that has a list of many companys, with their phone number, address, etc'
Each company is in it's own table, every table started like that: <table border="0">
I tried to use PHP to get all of the information, and use it later, like put it in a txt file, or just import into a database.
I assume that the way to achieve my goal is by using regex, which is one of the things that I really have problems with in php,
I would appreciate if you guys could help me here.
(I only need to know what to look for, or atleast something that could help me a little, not a complete code or anything like that)
Thanks in advance!!
I recommend taking a look at the PHP DOMDocument and parsing the file using an actual HTML parser, not regex.
There are some very straight-forward ways of getting tables, such as the GetElementsByTagName method.
<?php
$htmlCode = /* html code here */
// create a new HTML parser
// http://php.net/manual/en/class.domdocument.php
$dom = new DOMDocument();
// Load the HTML in to the parser
// http://www.php.net/manual/en/domdocument.loadhtml.php
$dom->LoadHTML($htmlCode);
// Locate all the tables within the document
// http://www.php.net/manual/en/domdocument.getelementsbytagname.php
$tables = $dom->GetElementsByTagName('table');
// iterate over all the tables
$t = 0;
while ($table = $tables->item($t++))
{
// you can now work with $table and find children within, check for
// specific classes applied--look for anything that would flag this
// as the type of table you'd like to parse and work with--then begin
// grabbing information from within it and treating it as a DOMElement
// http://www.php.net/manual/en/class.domelement.php
}
If You're familiar with jQuery (and even if You're not as it's command are simple enough) I recommend this PHP counterpart: http://code.google.com/p/phpquery/
If your HTML is valid XML, as in XHTML, then you could parse it using SimpleXML
I'm currently working a project that has me working with XML a lot. I have to take an XML response and decrypt each text node and then do various tasks with the data. The problem I'm having is taking the response and processing each text node. Originally I was using the XMLToArray library, and that worked fine I would change the XML into an array and then loop through the array and decrypt the values. However some of the XML response I'm dealing with have repeated tags and the XMLToArray library will only return the last values.
Is there a good way that I can take an XML response and process all the text nodes and easily putting the values into an array that has a similar structure to the response?
Thanks in advance.
I would use SimpleXML.
Here's a small example of using it. It loads and parses XML from http://www.w3schools.com/xml/plant_catalog.xml and then outputs values of "COMMON" and "PRICE" tags of each "PLANT" tag.
$xml = simplexml_load_file('http://www.w3schools.com/xml/plant_catalog.xml');
foreach ( $xml->PLANT as $plantNode ) {
echo $plantNode->COMMON, ' - ', $plantNode->PRICE, "\n";
}
If you have any problems with adapting it to your needs, just give an example of your XML so that we can help with it.
All those XML to array libraries are a remain of the times where PHP 4 would force you to write your own XML parser almost from scratch. In recent PHP versions you have a good set of XML libraries that do the hard job. I particularly recommend SimpleXML (for small files) and XMLReader (for large files). If you still find them complicate, you can try phpQuery.
You might want to give SimpleXML a try. Plus it comes by default in php so you dont need to install
Check out SimpleXML, it may offer a bit more for what you are looking for.
