XPath element which contains an attribute and whose parent's parent contains another attribute -


This is my first post and since I have seen very good answers, I thought I would try it. / P>

I'm trying to use XPath to get the specific element in an HTML document. This is an example based on Google web pages: 

  & lt; Html & gt; & Lt; Top & gt; & Lt; Title & gt; XPath Test & lt; / Title & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt; Name of the form = 'F' & gt; & Lt; Table & gt; & Lt; Tbody & gt; & Lt; TR & gt; & Lt; TD & gt; & Lt; Input name = 'q' type = "text" /> & Lt; / TD & gt; & Lt; / TR & gt; & Lt; / Tbody & gt; & Lt; / Table & gt; & Lt; / Form & gt; & Lt; / Body & gt; & Lt; / Html & gt; Using the above example (which is simplified for the purposes of asking for help), I would like to be able to find the input element whose name is 'q' and its ancestor named 5. Along with who is the parent = 'F'  
 For example, if I had to do this in the syntax of SWAT, which is located on an open source Web Automation Testing Library, the syntax would be as follows:  
 | AssertElementExists | Expression | Name = q; ParentElement.parentElement.parentElement.parentElement.parentElement.name = f | Input |  
 I am just starting to learn CPAD and am trying to understand how to get involved with axes. Is it possible to express it with XPath? If this is so, can some knowledgeable help?   
 
 
 You could:  
  // input [ Name = 'q' and ancestors-or-self: * [[name = 'f']] // - Input element whose name is 'q' and whose name is an ancestor with = 'F'  
 
 or 
 
  // input [@names = 'q' and ../../../../. ./../*[@name='f ']] // - Input element whose name is in the form of' q 'and 5 parent names, name =' f ' 
 < P> You can use this desktop to test your XPath expressions. a.

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...
