Get XML String in PHP with URL

I'm really new to the job as a web developer and I have a Problem that I cant solve alone, also I can't find any answers which fit my Problem.
So this is the Construct, I have a PHP Page with this Code:
<?php
$url = 'http://myserver.de/list.aspx';
$xml = new SimpleXMLElement($url);
$name = $xml->List->member->name;
?>
And I got this C#-Code from an aspx-project (list.aspx):
StringBuilder xmlBuilder = new StringBuilder();
xmlBuilder.Append("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
xmlBuilder.Append("<List>");
foreach (var nameandplz in fullname.Zip(plz, Tuple.Create))
{
xmlBuilder.Append("<member>");
xmlBuilder.Append("<name>" + nameandplz.Item1 + "</name>");
xmlBuilder.Append("<postcalcode>" + nameandplz.Item2 + "</postalcode>");
xmlBuilder.Append("</member>");
}
xmlBuilder.Append("</List>");
Context.Response.ContentType = "text/xml";
Context.Response.BinaryWrite(Encoding.UTF8.GetBytes(xmlBuilder.ToString()));
Context.Response.End();
So I just use the StringBuilder to build a String with XML.
fullname and plz are listed.
In my PHP-CIde i call the URL and the Problem is that the SimpleXMLElement doesnt write the XML-Code into the $xml.
I tried everything, i called the URL manually and the XML File is displayed correctly.
Do I use the wrong format to get the XML File per SimpleXMLElement?

To get the data from the URL you must set $data_is_url = true according to the PHP Documentation ( http://php.net/manual/fr/simplexmlelement.construct.php ); so XMLElement try to build an XML from the string given.
You can use the function libxml_get_errors to get XML errors.
So here a code that will get the content from the URL :
<?php
$url = 'http://myserver.de/list.aspx';
$xml = new SimpleXMLElement($url, 0, true);
$name = $xml->List->member->name;
Caution : you access List / Member / Name without testing if List Member or Name exists.

How to receive MultipartFormData on ASP.NET C#

I'm working with an iOS guy. He wants to upload images through WebAPI ASP.NET. I've to make a call that can receive those images.He said he is using AFNetworking to send data through AFMultipartFormData. My question is that how can I receive this at my end? Should I take the data in JSON format? Or what measures needs to be done for this purpose? I want to know the whole process as this is my first time working with MultipartFormData.UPDATEBased on the answer I used this:
[HttpPut]
public IHttpActionResult GetPatientFilesAction(int id, Model.Patients.PatientFiles patientFile)
{
Model.Patients.PatientFiles pFile=new Model.Patients.PatientFiles();
try
{
HttpPostedFile xmlFile = HttpContext.Current.Request.Files[0];
var fileForm = HttpContext.Current.Request.Form;
var fileKey = HttpContext.Current.Request.Form.Keys[0];
string[] jsonformat = fileForm.GetValues(fileKey);
pFile = Newtonsoft.Json.JsonConvert.DeserializeObject<Model.Patients.PatientFiles>(jsonformat[0]);
}
catch (Exception ex)
{
pFile.ErrorMessage = ex.ToString();
}
return Ok(pFile);
}
But the iOS guy got:
Request failed: unsupported media type (415)

Inside the web API controller you can access the image file using the code below :-
HttpPostedFile xmlFile = HttpContext.Current.Request.Files[0];
If you have more than one files posted, replace Files[0] with respective count 1 or 2 etc.
And then you can access the JSON using the code :
var fileForm = HttpContext.Current.Request.Form;
var fileKey = HttpContext.Current.Request.Form.Keys[0];
string[] jsonformat = fileForm.GetValues(fileKey);
var yourModel = JsonConvert.DeserializeObject<YourClassType>(jsonformat[0]);
If you have more than one json strings posted, replace jsonformat[0] with respective count 1 or 2 etc.

How to get XML-code of webpage that is opened in IE (without using WebRequest)?

I'm trying to get an XML-text from a wabpage, that is already opened in IE. Web requests are not allowed because of a security of target page (long boring story with certificates etc). I use method to walk through all opened pages and, if I found a match with page's URI, I need to get it's XML.
Some time ago I needed to get an HTML-code between body tags. I used method with IHTMLDocument2 like this:
private string GetSourceHTML()
{
Regex reg = new Regex(patternURL);
Match match;
string result;
foreach (SHDocVw.InternetExplorer ie in shellWindows)
{
match = reg.Match(ie.LocationURL.ToString());
if (!string.IsNullOrEmpty(match.Value))
{
mshtml.IHTMLDocument2 doc = (mshtml.IHTMLDocument2)ie.Document;
result = doc.body.innerHTML.ToString();
return result;
}
}
result = string.Empty;
return result;
}
So now I need to get a whole XML-code of a target page. I've googled a lot, but didn't find anything useful. Any ideas? Thanks.

Have you tried this? It should get the HTML, which hopefully you could parse to XML?
Retrieving the HTML source code

Navigating to DNN Module

I'm forming a newsletter with links to various html modules within my DNN website. I have access to each of their ModuleID's and I'm wanting to use that to get the url. The current approach (made by a third party developer) worked, but only to a degree. The url's are incorrectly formed when the Modules are located deeper in the website.
For example module located at www.website.com/website/articles.aspx is works fine, but a module located www.website.com/website/articles/subarticles.aspx won't. I know this is because the url is incorrectly formed.
Here's the current code:
DotNetNuke.Entities.Modules.ModuleController objModCtrlg = new DotNetNuke.Entities.Modules.ModuleController();
DotNetNuke.Entities.Modules.ModuleInfo dgfdgdg = objModCtrlg.GetModule(ContentMID);
TabController objtabctrll = new TabController();
TabInfo objtabinfoo = objtabctrll.GetTab(tabidfrcontent);
string tabnamefremail= objtabinfoo.TabName;
moduletitlefrEmail = dgfdgdg.ModuleTitle;
string readmorelinkpath = basePath + "/" + tabnamefremail + ".aspx";
ContentMID is the current module ID I'm looking at. I've tried to use Globals.NavigateURL, but that always crashes with Object reference not set to an instance of an object. error. Same thing when I use objtabinfoo.FullUrl so I'm currently at a loss as to how I get the specific modules URL.
EDIT: Here's some more code as to how the tabId is retrieved.
IDictionary<int, TabInfo> dicTabInfo12 = new Dictionary<int, TabInfo>();
ContentMID = Convert.ToInt32(dsNewsList.Tables[0].Rows[i]["ModuleID"]);
dicTabInfo12 = objTabctrl.GetTabsByModuleID(ContentMID);
if (dicTabInfo12.Count > 0)
{
string tester = ""; //Debug
foreach (KeyValuePair<int, TabInfo> item1 in dicTabInfo12)
{
tabidfrcontent = item1.Key;
}
}

You really should be using NavigateUrl to build the links ance if you have the tabid, you are golden.
string readMoreLinkPath = NavigateUrl(tabidfrcontent);
Nice and simple

Okay, colleague suggested this and it works great within a scheduler.
string linkPath = basePath + "/Default.aspx?TabID=" + tabID;
Will Navigate you to the correct tab ID. So this would be the best solution if you're forced to work within a scheduler where you can't use NavigateUrl without some major workarounds.

Html parser to get blog posts

I need to create a html parser, that given a blog url, it returns a list, with all the posts in the page.
I.e. if a page has 10 posts, it
should return a list of 10 divs,
where each div contains h1 and
a p
I can't use its rss feed, because I need to know exactly how it looks like for the user, if it has any ad, image etc and in contrast some blogs have just a summary of its content and the feed has it all, and vice-versa.
Anyway, I've made one that download its feed, and search the html for similar content, it works very well for some blogs, but not for others.
I don't think I can make a parser that works for 100% of the blogs it parses, but I want to make the best possible.
What should be the best approach? Look for tags that have its id attribute equal "post", "content"? Look for p tags? etc etc etc...
Thanks in advance for any help!

I don't think you will be successful on that. You might be able to parse one blog, but if the blog engine changes stuff, it won't work any more. I also don't think you'll be able to write a generic parser. You might even be partially successful, but it's going to be an ethereal success, because everything is so error prone on this context. If you need content, you should go with RSS. If you need to store (simply store) how it looks, you can also do that. But parsing by the way it looks? I don't see concrete success on that.

"Best possible" turns out to be "best reasonable," and you get to define what is reasonable. You can get a very large number of blogs by looking at how common blogging tools (WordPress, LiveJournal, etc.) generate their pages, and code specially for each one.
The general case turns out to be a very hard problem because every blogging tool has its own format. You might be able to infer things using "standard" identifiers like "post", "content", etc., but it's doubtful.
You'll also have difficulty with ads. A lot of ads are generated with JavaScript. So downloading the page will give you just the JavaScript code rather than the HTML that gets generated. If you really want to identify the ads, you'll have to identify the JavaScript code that generates them. Or, your program will have to execute the JavaScript to create the final DOM. And then you're faced with a problem similar to that above: figuring out if some particular bit of HTML is an ad.
There are heuristic methods that are somewhat successful. Check out Identifying a Page's Primary Content for answers to a similar question.

Use the HTML Agility pack. It is an HTML parser made for this.

I just did something like this for our company's blog which uses wordpress. This is good for us because our wordress blog hasn't changed in years, but the others are right in that if your html changes a lot, parsing becomes a cumbersome solution.
Here is what I recommend:
Using Nuget install RestSharp and HtmlAgilityPack. Then download fizzler and include those references in your project (http://code.google.com/p/fizzler/downloads/list).
Here is some sample code I used to implement the blog's search on my site.
using System;
using System.Collections.Generic;
using Fizzler.Systems.HtmlAgilityPack;
using RestSharp;
using RestSharp.Contrib;
namespace BlogSearch
{
public class BlogSearcher
{
const string Site = "http://yourblog.com";
public static List<SearchResult> Get(string searchTerms, int count=10)
{
var searchResults = new List<SearchResult>();
var client = new RestSharp.RestClient(Site);
//note 10 is the page size for the search results
var pages = (int)Math.Ceiling((double)count/10);
for (int page = 1; page <= pages; page++)
{
var request = new RestSharp.RestRequest
{
Method = Method.GET,
//the part after .com/
Resource = "page/" + page
};
//Your search params here
request.AddParameter("s", HttpUtility.UrlEncode(searchTerms));
var res = client.Execute(request);
searchResults.AddRange(ParseHtml(res.Content));
}
return searchResults;
}
public static List<SearchResult> ParseHtml(string html)
{
var doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(html);
var results = doc.DocumentNode.QuerySelectorAll("#content-main > div");
var searchResults = new List<SearchResult>();
foreach(var node in results)
{
bool add = false;
var sr = new SearchResult();
var a = node.QuerySelector(".posttitle > h2 > a");
if (a != null)
{
add = true;
sr.Title = a.InnerText;
sr.Link = a.Attributes["href"].Value;
}
var p = node.QuerySelector(".entry > p");
if (p != null)
{
add = true;
sr.Exceprt = p.InnerText;
}
if(add)
searchResults.Add(sr);
}
return searchResults;
}
}
public class SearchResult
{
public string Title { get; set; }
public string Link { get; set; }
public string Exceprt { get; set; }
}
}
Good luck,
Eric
