How can i merge multiple xml into single xml in java -


Consider that I have 2xml files that are of the same framework, not

xml1 : 

  & lt; Digest Type Name = "Blog" & gt; & Lt; To & gt; Xxx@xx.org< / FromEmail & gt; & Lt; EmailTimeStamp & gt; & Lt; / EmailTimeStamp & gt; & Lt; EmailSubject & gt; & Lt; / EmailSubject & gt; & Lt; BlogName href = "" & gt; XML merger & lt; / Blogname & gt; & Lt; Blog calculation = "2" & gt; & Lt; ListPost & gt; & Lt; Title href = "" & gt; Title & lt; / Heading & gt; & Lt; CommentCount & gt; 10 & lt; / CommentCount & gt; & Lt; Content & gt; Post content ... & lt; / Content & gt; & Lt; / ListBlogPost & gt; & Lt; ListPost & gt; & Lt; Title href = "" & gt; Title 1 & lt; / Heading & gt; & Lt; CommentCount & gt; 10 & lt; / CommentCount & gt; & Lt; Content & gt; Post content ... & lt; / Content & gt; & Lt; / ListBlogPost & gt; & Lt; / Blog & gt; & Lt; / DigestType & gt;

xml2: 

  & lt; Digest Type Name = "Blog" & gt; & Lt; To & gt; Xxx@xx.org< / FromEmail & gt; & Lt; EmailTimeStamp & gt; & Lt; / EmailTimeStamp & gt; & Lt; EmailSubject & gt; & Lt; / EmailSubject & gt; & Lt; BlogName href = "" & gt; XML merger & lt; / Blogname & gt; & Lt; Blog calculation = "2" & gt; & Lt; ListPost & gt; & Lt; Title href = "" & gt; Title 2 & lt; / Heading & gt; & Lt; CommentCount & gt; 1 & lt; / CommentCount & gt; & Lt; Content & gt; Content ... & lt; / Content & gt; & Lt; / ListBlogPost & gt; & Lt; ListPost & gt; & Lt; Title href = "" & gt; Title 3 & lt; / Heading & gt; & Lt; CommentCount & gt; 23 & lt; / CommentCount & gt; & Lt; Content & gt; Content ... & lt; / Content & gt; & Lt; / ListBlogPost & gt; & Lt; / Blog & gt;

Now I can add these 2 XML to 

  & lt; DigestType name = "blogs" & gt; & Lt; To & gt; Xxx@xx.org< / FromEmail & gt; & Lt; EmailTimeStamp & gt; & Lt; / EmailTimeStamp & gt; & Lt; EmailSubject & gt; & Lt; / EmailSubject & gt; & Lt; BlogName href = "" & gt; XML merger & lt; / Blogname & gt; & Lt; Blog Count = "4" & gt; & Lt; ListPost & gt; & Lt; Title href = "" & gt; Title & lt; / Heading & gt; & Lt; CommentCount & gt; 10 & lt; / CommentCount & gt; & Lt; Content & gt; Post content ... & lt; / Content & gt; & Lt; / ListBlogPost & gt; & Lt; ListPost & gt; & Lt; Title href = "" & gt; Title 1 & lt; / Heading & gt; & Lt; CommentCount & gt; 10 & lt; / CommentCount & gt; & Lt; Content & gt; Post content ... & lt; / Content & gt; & Lt; / ListBlogPost & gt; & Lt; ListPost & gt; & Lt; Title href = "" & gt; Title 2 & lt; / Heading & gt; & Lt; CommentCount & gt; 1 & lt; / CommentCount & gt; & Lt; Content & gt; Content ... & lt; / Content & gt; & Lt; / ListBlogPost & gt; & Lt; ListPost & gt; & Lt; Title href = "" & gt; Title 3 & lt; / Heading & gt; & Lt; CommentCount & gt; 23 & lt; / CommentCount & gt; & Lt; Content & gt; Content ... & lt; / Content & gt; & Lt; / ListBlogPost & gt; & Lt; / Blog & gt; & Lt; / DigestType & gt;

I am using Java Can someone help me find solutions?

Thanks uma

Use it: 

  XPath xpath = XPathFactory.newInstance (). NewXPath (); // Load Document xml1 = (document) xpath.evaluate ("/", new input source ("xml1.xml"), XPathConstants.NODE); Nodelist list post = (nodelist) xpath.evaluate ("/ digest type / blog / list post", new input source ("xml2.xml"), XPathConstants.NODESET); // Merge element blog = (element) xpath.evaluate ("/ digest type / blog", xml1, XPathConstants.NODE); (Int i = 0; i & lt; list.posts.length (); i ++) {node list post = list post.system (i); Blog.appendChild (xml1.adoptNode (listPost)); } // Set blog.setAttribute ("count", xpath.evaluate ("count (list post)", blog)); // print DOMImplementationLS impl = (DOMImplementationLS) xml1.getImplementation (); Println (impl.createLSSerializer () writeToString (xml1).);

(Your XML is not created properly, I think the element starts with the correct name.)

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...
