I have around 15,000 XML files in a folder, an example of a XML filename is; 000010000.img.xml
Each XML file contains specific information I need in a single text file.
Each XML file has the exact same structure aside from the information presented.
Here is what I want to focus in on (within the XML file)
<imgdir name="000010000.img">
<imgdir name="info">
<int name="version" value="10" />
<int name="cloud" value="0" />
<int name="town" value="0" />

A batch file does not work; as you can see in my other thread: Batch script not working?
I need a C# application to open each XML file, grab specific information (that I will specify below), write that information into a single text file, and rinse and repeat till every XML file has been read.
Using the XML file snippet/actual XML file information posted above, here is how I need the text file text structure to be;
[10000]
total=4
sp 0 -389 183 999999999
sp 0 -416 185 999999999
sp 0 -450 183 999999999
out00 2 1080 541 20000
I just cannot wrap my head around on how to do this in a c# console application.
I am asking for help, anything is appreciated!
string[] files = Directory.GetFiles(#"SomeWhere");
List<string> result = new List<string>();
foreach (string file in files)
{
string[] lines = File.ReadAllLines(file);
// Grab information from the lines and store it in result
// by using result.Add(...) or result.AddRange(...)
}
File.WriteAllLines(#"AlsoSomewhere", result);
Here is a quick and dirty program I wrote up. I had to add a root to your XML file for it to play nice-nice with the program. I hope this helps!
Code:
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Xml.Linq;
namespace ConsoleApp5 {
public class Program {
public static void Main(string[] args) {
string test = getValuesOneFile("xmltest.xml");
Console.WriteLine(test);
Console.ReadLine();
}
public static string getValuesOneFile(string fileName) {
string finalString = "";
XElement xmlDocument = XElement.Load((fileName));
XElement infoImgDir = GetImgDir(xmlDocument, "info");
finalString += "[" + GetInt(infoImgDir, "returnMap") + "]\n";
finalString += "total=" + GetChildrenCount(GetImgDir(xmlDocument,"portal")) + "\n";
IEnumerable<XElement> portals = GetImgDir(xmlDocument, "portal").Elements();
foreach (XElement currentPortal in portals) {
finalString += GetString(currentPortal, "pn") + " ";
finalString += GetInt(currentPortal, "pt") + " ";
finalString += GetInt(currentPortal, "x") + " ";
finalString += GetInt(currentPortal, "y") + " ";
finalString += GetInt(currentPortal, "tm") + "\n";
}
return finalString;
}
public static XElement GetImgDir(XElement file, string imgDirName) {
return file.Descendants("imgdir").FirstOrDefault(x => (string)x.Attribute("name") == imgDirName);
}
public static int GetInt(XElement data, string attribName) {
var element = data.Descendants("int").FirstOrDefault(x => (string)x.Attribute("name") == attribName);
if (element == null)
return 0;
var value = (int?)element.Attribute("value");
if (value == null)
return 0;
return value.Value;
}
public static string GetString(XElement data, string attribName) {
var element = data.Descendants("string").FirstOrDefault(x => (string)x.Attribute("name") == attribName);
if (element == null)
return "";
var value = (string)element.Attribute("value");
if (value == null)
return "";
return value;
}
public static int GetChildrenCount(XElement data) {
return data.Elements().Count();
}
}

I have some XML data that resides in an XML file and I am trying to get it into datatables. I have tried putting it into a Dataset. I have tried putting it in XML nodes. However, it all seems random and just all over the place and it's not working. I have tried to include a summarized version of how the data looks below. How can I extract it into clear tables and rows and columns? Also, I am not sure if this would help or not, but this XML is created from 4 tables that are then extracted to an XML file using and XSLT file. Is there a way to do it in REVERSE to take the XSLT and XML file into the original datatables?
<obj name="TableName0">
<int name="ANumberThatsAColumn1" val="" />
<int name="ANumberThatsAColumn2" val="" />

Here is a conceptual example for you.
XML shredding is happening in T-SQL via two XQuery methods:
.node()
.value()

Im asking this because i couldnt find a answer to my question but if there is please link it in the answers.
XML FILE is now added to the post as you can see.
I really dont know why it keeps happening but ye hope you guys can help.
Some suggestions to move forward:
static void Main()
{
XmlDocument xml = new XmlDocument();
// Catch Exception, print message and bail out.
try{
// vv "LoadXml" replaced by "Load"
xml.Load("c:\\SaintGobain_Pam_20210118.xml");
}
catch(Exception ex)
{
Console.WriteLine("OOps: {0}", ex.Message);
return;
}
string _byteOrderMarkUtf8 =
Enconding.UTF8.GetString(Encoding.UTF8.GetPreamble());
if (xml.StartWith(_byteOrderMarkUtf8))
{
var lastIndexOfUtf8 = _byteOrderMarkUtf8.Length - 1;
xml = xml.Remove(0, _byteOrderMarkUtf8.Length - 1);
}
// vv replace XPath expression
XmlNodeList xnLista = xml.SelectNodes(#"//Pages/Page");
foreach(XmlNode xn in xnLista)
{
string formulario = xn["FormTypeName"].InnerText;
string Value = xn["Value"].InnerText;
string FileName = xn["ImportFileName"].InnerText;
// Correct syntax:
Console.WriteLine("Formulário: {0}, Value: {1} ,FilePath: {2}",formulario, Value, FileName);
}
}
Then manually sanitize (for now) the source file:
Delete ErrorCode="20" ErrorMessage="Illegal file format (\\umm\c$\acxmlaid\SaintGobain\20210118\ZE80047860.pdf)" />
And give it another try.
I am trying to pull the attribute values for each of the element, that is in this XMl Schema file(XML below). I want the attribute values for the following: type, label, CompTypes, readonly, hidden, and required.
For example, here is one of the elements in the XML file:
<element type="xpowercomponent_FeaturedTiles" UID="40204fc9b5424b349e03134d777d29bc" label="Featured Tiles" readonly="false" hidden="false" default="" required="false" Component="" CompTypes="ThemedTileSetComponent;ThemedTileSetElectedComponent;" AutoEmbed="" WrappedUp="" AllowWrappingChange="" />
The expected result for this element should be:
xpowercomponent_FeaturedTiles, Featured Tiles, ThemedTileSetComponent,
ThemedTileSetElectedComponent, readonly="false", hidden="false",
required="false"
I have started a C# app to get this information, however it is not getting all the information properly. Could you please take a look at the code, and see how this can be fixed or improved? Is there a better way of approaching this, maybe LINQ? The ultimate goal is to then output these attribute values/data in a CSV file.

you can use System.Xml.Linq to get all the elements and the required attributes as below
XDocument document = XDocument.Load(#"D:\New Text Document.xml");
var eleCollection = document.Elements("element");
foreach (var element in eleCollection)
{
var type = element.Attribute("Type").Value;
}
This is easiest way one can use for loops on nodes to get the information in each node.
use node.ChildNodes property to get the chilenodes.
XmlDocument doc = new XmlDocument();
doc.Load("filepath");
//Here Path could be- "//ElementType" ---> this will give all nodes with name ElementType
XmlNodeList nodes= doc.SelectNodes("//give path of nodes you want attributes for");
foreach (XmlNode node in nodes)
{
//Assuming you want information of element tags
foreach (XmlNode child in node.ChildNodes)
{
string name= node.Attributes["type"].Value;
string name= node.Attributes["label"].Value;
}
}
I've got the following XML:
<...>
<...>
<tabular>
<time from="2014-05-22T10:00:00" to="2014-05-22T12:00:00" period="1">
<symbol number="3" numberEx="3" var="03d" />
<precipitation value="0" />
<windDirection deg="191.8" code="SSW" />
<windSpeed mps="1.3" />
<temperature unit="celsius" value="16" />
<pressure unit="hPa" value="1010.6" />
</time>

I've managed with LINQ to get the tabular list:
var tabular = doc.Root.Descendants("tabular").ToList();
tabular count is now 1. What I want is a list of children of tabular. I've tried the extra descendant:
var tabular = doc.Root.Descendants("tabular").Descendants().ToList();
But that return a list of every descendant of tabular, resulting in a list where time, symbol, precipitation and so on is in the list. How can I get a list where the list contains time nodes of tabular?
I want a list of all time nodes, so I can serialize it to a object and access the values
Use Elements instead of Descendants if you want to get only direct children of tabular
var tabular = doc.Root.Descendants("tabular").Elements().ToList();
UPDATE: Hints for parsing time elements into objects
var times =
from t in xdoc.Descendants("tabular").Elements()
let symbol = t.Element("symbol")
let temperature = t.Element("temperature")
select new
{
From = (DateTime)t.Attribute("from"),
To = (DateTime)t.Attribute("to"),
Period = (int)t.Attribute("period"),
Symbol = new
{
Number = (int)symbol.Attribute("number"),
NumberEx = (int)symbol.Attribute("numberEx"),
Var = (string)symbol.Attribute("var")
},
Precipitation = (int)t.Element("precipitation").Attribute("value"),
WindSpeed = (double)t.Element("windSpeed").Attribute("mps"),
Temperature = new
{
Unit = (string)temperature.Attribute("unit"),
Value = (string)temperature.Attribute("value")
}
};
Output:
[
{
From: "2014-05-22T10:00:00",
To: "2014-05-22T12:00:00",
Period: 1,
Symbol: { Number: 3, NumberEx: 3, Var: "03d" },
Precipitation: 0,
WindSpeed: 1.3,
Temperature: { Unit: "celsius", Value: "16" }
},

in my xml file how i can select the value for attributes TagId in ServiceAssignment elements by linq to xml

i try this code but give me a null exception
var MyList = doc.Root.Elements("ServiceAssignment").Select(c=>c.Attribute(("TagId")).Value).ToList();
You have namespaced elements in the document so you need to include them in your queries.
XNamespace itemNs = "urn:schema:Microsoft.Rtc.Management.ScopeFramework.2008";
XNamespace assignmentNs = "urn:schema:Microsoft.Rtc.Management.Settings.ServiceAssignment.2008";
var query =
from item in doc.Descendants(itemNs + "Item")
from assignment in item.Descendants(assignmentNs + "ServiceAssignment")
select (long)assignment.Attribute("TagId");

var doc = XDocument.Parse(xmlString);
var TagIds = doc.Descendants()
.Elements()
.Where(e =>
e.HasAttributes &&
e.Name.LocalName.Equals("ServiceAssignment") &&
e.Attribute("TagId") != null)
.Select(e => e.Attribute("TagId").Value);
Your XML contains namespaces, so you can't just compare the full name.
If you don't care about the namespaces, you can use XName.LocalName:
var result = from element in doc.Root.Descendants()
where element.Name.LocalName == "ServiceAssignment"
select (int)element.Attribute("TagId");
You can try with this code
var result = from item in XElement.Load("YourFile.xml").Root.Elements("ServiceAssignment")
where item.Attribute("TagId") == value
select item ;
