iphone - Parsing SO RSS feed using TouchXML, no <entry> tags found -


I am trying to parse a stack overflow RSS feed for a specific question:

For this, I am using the TouchXML library to have a problem in the following code: 

  CXMLDocument * parser = [[CXML document alloc] initWithData: sourceData option: 0 error: zero] ; NSArray * allEntries = [Parsons nodesforxpath: @ "// entry" error: zero]; NSLog (@ "Entries entered:% d", [All entries count]); // Returns 0

The count of all entries in the NSLog details feed should be returned. In this case it should be '3', the problem is that it gives 0.

I found that this code works: 

  CXMLDocument * preParser = [[CXML document alloc] initWithData: sourceData option: 0 error: zero]; NSString * sourceStringUTF8 = [Preprors XMLString]; [Preemptor release]; CXML Document * Pars = [[CxML Document Alok] InitVheDatata: [sourceStringUTF8 Data Wrapping Encoding: NSUTF8 String Encoding] Option: 0 Error: Zero]; NSArray * allEntries = [Parsons nodesforxpath: @ "// entry" error: zero]; NSLog (@ "Entries entered:% d", [All entries count]); // Returns 3, which is ok

but it seems to be used (it is probably) and introduces some other sporadic bugs.

As far as I know the Expath expression is correct I have also checked it using the page.

Can anyone help me with this problem, or can I tell me in the right direction.

Thank you.

I had a very similar problem. This is something with the XML namespace, which is not very well supported by TouchXML (a known issue).

I believe that in your hack, the namespace was not passed in the other parser, why it works.

An easy way is to change only 

  & lt; Html xmlns = "http://www.w3.org/1999/xhtml" lang = "n" xml: lang = "en" & gt;

only 

  & lt; Html & gt;

And xPath now works.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
