sample xml file with multiple records

thanks vinod for posting the code. You might want to create an Employee object that takes a XPathNavigator as a constructor parameter if a business layer makes sense. May 4, 2020 March 14, 2020 by admin. The following XML file is used in various examples in the LINQ to XML documentation. that represents the employee information to be displayed. It then flattened the "topping" sub path and merged those results with the previously calculated set of rows. You get one row in the data set for each node that was matched by the data set's XPath with a column schema that looked something like this: Notice that in the "Topping" column we actually get a value, that's because if a selected node contains any child elements that repeats, like , and that child element has no child elements, the value of the last instance ends up being the value stored in that column. XML files look like HTML files but XML has its custom tags. The actual implementation of the NestedXMLDataSet extracts its data directly from the same in-memory copy of the XML DOM document used by its parent. Thanks Martin for the this Performance information. // Attempt to display employee details, // Note: You would want to add data validation to ensure. So the drawback with this approach, is that you cannot sort across *all* of the nested data, even though the presentation of the data on-screen with a table makes it look like you can. The name of this column will be the same as the node/tag name of the selected node. Chocolate Above file URL – This happens because anytime the parent's row changes, they reload their data to match. your code rocks !! Maple, filling thanks Martin. you can modify as you need and update as per your requirements. Regular The .NET framework has a lot of APIs to parse XML, one way is to use XPathDocument/XPathNavigator, here is a simple example: XPathDocument document = new XPathDocument(@"..\..\XMLFile1.xml"); XmlNodeList empNodeList = document.SelectNodes("/Employees/Record[EmployeeId = " + employeeId + "]"); Console.WriteLine("Employee Name : " + name); Console.WriteLine(" Address1: " + address1); This code should do your job. That will help when you need to testing for large data. We will start off by creating a data set like we normally would, and then define some markup with spry attributes and data references in it to describe how we would like to generate our table: We end up with the following table when viewed in a browser: Not exactly what we wanted, but its a start. This is because whenever you sort or filter a nested data set, it applies those operations to the set of data associated with each row of the parent data set. //------------------------------------------------------------. If the selected node has child elements with no element children: Create a column for every attribute on the child element. I need to parse the above xml file based on the EmployeeID in C#, I want a function to which I can pass the EmployeeID and the Function will parse the XML file and return the details of a particular EmployeeID.? Another way to think about this is: inside a nested data set, there are multiple data sets, one for each row of the parent data set. The schema for the rows in our data set is the same as in our previous example, the exception being that now each row has the correct/expected topping value and id in it: This example uses the exact same data set as the previous example, but it illustrates how you access the attributes of the nodes selected by the sub paths. Glazed Above file URL – The value for the attribute is stored in this column. The "subPaths" constructor option can also take an array of sub path strings. Some Student Details Added for testing. For example, some schemas allow zero, one, or more child elements with the same name. Here, You can get a large XML file, many records, and multiple data. how can I change the string format to read the string value. Notice also, that we have "undefined" values in our "Batter" column. Just after posting the reply for this post I saw your reply and somehow I feel your code has better performance. Sample XML URL – In this example, we will combine the values of the id attributes from the , , and nodes to produce a unique SKU number. Sprinkles Here is an alternate example that separates the data retrieval code from the presentation layer. The name of the column will be the node/tag name of the child element. If the selected node has no element children, create a column to store any text/cdata value it has underneath it. // Attempt to extract XML data for specified XPath query, // Create XPathDocument against supplied reader, // Create XPathNavigator to parse XML data, // Determine if XML namespace manager provided. Each record contains three fields. Let us know if we forgot to add the files that you want. I figured it out.. anyways thanks a lot for your help. In Excel, I clicked Developer > Source > XML Maps > Add, then I selected the XML schema file from above and added it to my worksheet. You can find below a list for sample files that will be free to use, download, and modify as you want. If anyone knows how to do it. XML is a Markup Language as an HTML(Hypertext Markup Language). As an example, suppose that we want to write out all of the toppings available for a given item: You can still use nested data sets in combination with its parent data set to generate a table that looks something like what we saw in the previous section: Although it looks similar to the tables from the previous "Controlling the Flattening Process" section: there are some important differences. Sample XML File (books.xml) 10/27/2016; 2 minutes to read; In this article The following XML file is used in various samples throughout the Microsoft XML Core Services (MSXML) SDK. // Define XML reader settings to optimize parse operation, // Select node for employee with specified identifier, // If the XML data utilized a default XML namespace or, // if some of the employee data nodes were associated, // via a prefix to an XML namespace, an XmlNamespaceManger. When you sort or filter the nested data set, the sorting and filtering functions operate on each individual internal data set inside the nested data set. // would need to be created and passed as a parameter. Sample XML URL – I will try your code and martin's code and which ever give good performace and fit my need I wlll use that code. Here I have provided you a sample file for your testing used and you can modify as much time you want. !, I have one more questions, In my case the EmployeeID is string. that represents an employee record. The value of the "subPaths" constructor option can be an XPath string that is relative to the data set's main XPath, which describes the path down to the structure you want to include in the flattening process. Sample XML File. If no record found for specified employee identifier, returns, // Attempt to get record for specified employee identifier, // Create stream against XML data source, // Stream could have been passed as a parameter or the path to XML. But, if you click on the Topping header, the toppings seem to sort only within groups. Any time the current row of the parent data set changes, the data inside the nested data set is updated automatically. The sample XML(Extensible Markup Language) file will provide you file that contains XML data that will be used for your testing purpose. Notice how the other 2 lists, which use nested data sets, change? For instance, if you click on the headers for ID, Name, and Price Per Unit, you will notice that the entire table seems to sort based on those values. ... Another way to think about this is: inside a nested data set, there are multiple data sets, one for each row of the parent data set. Exactly how the nested data set extracts its data from the parent data set depends on the actual implementation of both the master and nested data sets. You do this by passing a "subPaths" constructor option. The main reason they are ignored is because it's too hard to intelligently flatten nested repeating data into something predictable, especially when many XML schemas allow for variations in the format. If anyone knows how to … XML files are stander ways to store and exchange data between the internet like JSON. This schema demonstrates a couple of nested data scenarios that previous versions of Spry (Pre-Release 1.4 and earlier) had a hard time dealing with, specifically the use of sub-structures like in this example: when the node (XPath: /items/item) was selected by the Data Set. Nested data sets derive their data from another data set, considered its parent/master. Visit our UserVoice Page to submit and vote on ideas! Displays the details of the supplied employee record. If expression did not evaluate, returns. I have created as per my understanding and knowledge. Any time the current row of the parent data set changes, the nested data set simply swaps in the data from the internal data set that is associated with that parent row. XML files are also viewed in the browser and it is human and machine-readable. It is editable by any text editor. I hope I am making myself clear. If you use this file to update existing accounts, any fields that aren't defined in the XML file are ignored during the update. is a null reference (Nothing in Visual Basic). I mapped each element in the XML Source window to the corresponding column in the Excel worksheet (the "Brand" element is mapped to A:A, the "Model" element is … XML Contents sender/receiver Information. I have a multi record  XML file, I need to parse the XML file based on the EmployeeID,      5690 John, Wagh 4 Lion Rd WestBurg VA 23233               5691 Mary, Delay 65 Welsh Rd WestBurg VA 23233          ................    .........................    ........................    ........................  . The schema for our data set rows now looks something like this: Now lets try to fix the problem by giving the data set a hint that it needs to include the repeated nodes in its flattening process. // expected child nodes are present in navigator. The XPath expression used to query the XML data. This makes it ideal for writing out data that is grouped by data in the parent data set. NestedXMLDataSets do not have any ability to load data off the wire, from a server. It then flattened the sub path for "batters/batter" and joined the results of that with its original set of rows. that represents the data record for an employee with the specified identifier. I wil try read some more from MDSN Forum. You’ll be auto redirected in 1 second. For Spry Pre-Release 1.5, we have added the ability for the user to give the data set hints on how to flatten the data. , None It should be explicitly stated that if new XML data must be loaded from the server, that the actual loading be done by the parent Spry.Data.XMLDataSet.
