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"];
}

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 = $xmlarray['response']['MESSAGE'];
BTW This solution is found here
PHP convert XML to JSON
I did it as an array as sometimes objects are a little hard to process. You can easily just do the first line and address it as an object. (If those are the only variables you need then an array works fine. Ex: the 'Plan' data will be messed up in an array as it appears twice)
There can be some issues such as the MESSAGE not appearing or the XML returning a failure but I think you should know how to code around missing datum.
I have
this xml file
and i'm trying to access to the value of attribute permission in the tag yt:accessControl in php
echo (string)$xmlyt->entry->children('yt')->{'accessControl'}->attributes()->$actionAttr."------------";
but i have the error
Node no longer exists
Understanding how SimpleXML works and XML generally is greatly beneficial to doing this...
You can discover things through trial and error and end up with something like this:
$sxml=simplexml_load_file('http://gdata.youtube.com/feeds/api/videos/'.$videoID.'?v=2');
$yt = $sxml->children('http://gdata.youtube.com/schemas/2007');
print_r($yt->accessControl->attributes());
print_r($yt->accessControl[4]->attributes());
For instance, this will give you permissions for the first and fifth actions, which happen to be comment and embed ATM (should probably loop through all to identify the ones you're interested instead of relying on the order).
Hope this helps,

Ok, I am working on a flatfile shoutbox, and I am trying to achieve a way to get the username from the flatfile and making it a variable so I can use it to make a call to the database to check if the user is admin so they can delete/ban users directly from the shoutbox.
This is an example line in the flatfile
<div><i><div class='date'>12/08/2012 18:56 pm </div></i> <div class='groupAdmin'><b>Admin</b></div><b>kira423:</b> hiya :D</div>
So I wanna take the username which is kira423 in this case and create a variable such as $shoutname and make it equal kira423
I have tried a google search and looked around on here, but was unable to find an answer, so I am hoping that I can get some insight on how to do this with a question of my own here.
Thanks,
Kira
You should use preg_match for those tasks like this:
preg_match_all('|<div class=\'date\'>(?P<date>.*?) .*<a.*>(?P<user>.*)</a>|i', $data, $matches);
var_dump($matches);
Interating through all array elements:
foreach ($matches['user'] as $key => $user) {
var_dump($user);
}
I think you should just parse each line in the flatfile as HTML (there are simple HTML tags used), just like described in PHP Parse HTML code (or type "php parse HTML" in google). Then you may access the username (kira123) from an array or whatever.
PS HTML is not the best way you can store messages to display. Even CSV seems to be better - it'd be "kira123;date;some text" - it's easier to read and to access each part. When displaying, use the standar decorator pattern.
I'm trying to parse this feed: http://musicbrainz.org/ws/1/artist/c0b2500e-0cef-4130-869d-732b23ed9df5?type=xml&inc=url-rels
I want to grab the URLs inside the 'relation-list' tag.
I've tried fetching the URL with PHP using simplexml_load_file(), but I can't access it using $feed->artist->relation-list as PHP interprets "list" as the list() function.
I have a feeling I'm going about this wrong (not much XML experience), and even if I was able to get hold of the elements I want, I don't know how to extract their attributes (I just want the type and target fields).
Can anyone gently nudge me in the right direction?
Thanks.
Matt
Have a look at the examples on the php.net page, they actually tell you how to solve this:
// $feed->artist->relation-list
$feed->artist->{'relation-list'}
To get an attribute of a node, just use the attribute name as array index on the node:
foreach( $feed->artist->{'relation-list'}->relation as $relation ) {
$target = (string)$relation['target'];
$type = (string)$relation['type'];
// Do something with it
}
(Untested)
are there build in functions in latest versions of php specially designed to aid in this task ?
Use a DOM parser like SimpleXML to split the HTML code into nodes, and walk through the nodes to build the array.
For broken/invalid HTML, SimpleHTMLDOM is more lenient (but it's not built in).
String replace and explode would work if the HTML code is clean and always the same, as soon as you have new attributes it will brake.
So only dependable solution would be using regular expressions or XML/HTML parser.
Check http://php.net/manual/en/book.dom.php
An alternative to using a native DOM parser could be using YQL. This way you dont have to do the actual parsing yourself. The YQL Web Service enables applications to query, filter, and combine data from different sources across the Internet.
For instance, to grab the HTML table with the class example given at
http://www.w3schools.com/html/html_tables.asp
you can do
$yql = 'http://tinyurl.com/yql-table-grab';
$yql = json_decode(file_get_contents($yql));
print_r( $yql->query->results );
I've deliberated shortened the URL so it does not mess up the answer. $yql actually links to the YQL API, adds some options and contains the query:
select * from html
where xpath="//table[#class='example']"
and url="http://www.w3schools.com/html/html_tables.asp"
YQL can return JSON and XML. I've made it return JSON and decoded this then, which then results in a nested structure of stdClass objects and Arrays (so it's not all arrays). You have to see if that fits your needs.
You try out the interactive YQL console to see how it works.
i dont know if this is the faster , but you can check this class (using preg_replace)
http://wonshik.com/snippet/Convert-HTML-Table-into-a-PHP-Array
If you want to convert the html-description of a table, here's how I would do it:
remove all closing tags (</...>) ( http://php.net/manual/de/function.str-replace.php)
split string at opening tags (<...>) using a regular expression ( http://php.net/manual/en/function.split.php)
You have to work out the details on your own, since I do not know if you want to handle different lines as subarrays or you want to merge all lines into one big array or something else.
you could use the explode-function to turn the table cols and rows into arrays.
