I have some xml similar to this:
<?xml version="1.0" encoding="utf-8" ?>
<data>
<resources>
<resource key="Title">Alpha</resource>
<resource key="ImageName">Small.png</resource>
<resource key="Desc">blah</resource>
</resources>
</data>
using linq-xml how can i assign each resource here as a key value pair with the ViewData collection.
Thanks.
var doc = XDocument.Parse(documentString);
foreach (var res in doc.Root.Descendants("resources")) {
ViewData[(string) res.Attribute("key")] = res.Value;
}
Should work.
assuming you loadt hat xml into an XDocument, you can just iterate on teh descendants. here's a quick example, if it's coming from a string:
var doc = XDocument.Parse(docAsString);
foreach (var resource in doc.Descendants("resource"))
ViewData[resource.Attribute("key").Value] = resource.Value;

I have a c# console application where I update, add and delete information from an xml which works so far. But when i show the xml in my console with WriteLine it shows like this:
<ArrayOfKunde xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Kunde id="1">
<firstName>Hasan 2</firstName>
<lastName>sad</lastName>
<adress>sdfd</adress>
<birthday>vcxbgf</birthday>
<bankDetails>bcgh</bankDetails>
</Kunde>
<Kunde id="2">
<firstName>ghf</firstName>
<lastName>nbv</lastName>
<adress>bjk</adress>
<birthday>hjvn</birthday>
<bankDetails>jhgj</bankDetails>
</Kunde>
<Kunde id="3">
<firstName>mbn,</firstName>
<lastName>hgj</lastName>
<adress>ghj</adress>
<birthday>ghjg</birthday>
<bankDetails>hghj</bankDetails>
</Kunde>
</ArrayOfKunde>
it is probably due to my code to print it:
string filepath = "customerdatabase2.xml";
var xDoc = XDocument.Load(filepath);
Console.WriteLine(xDoc);
I wanted to ask if there is any way for me to filter what is shown? For example I do not want to show:
<ArrayOfKunde xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
Use: XDocument.Descendants
So your code can be:
string filepath = "customerdatabase2.xml";
var xDoc = XDocument.Load(filepath);
foreach (var node in xDoc.Descendants().Skip(1))
Console.WriteLine(node);
But this is very much tied to your Xml structure. Note that I am skipping 1st descendant because that will be the Top level ArrayOfKunde node.
I need to change ALL the Tag name to Lowercase but leave the InnerText or Value as it is. I just found the thread showing how to change the casing for the entire document but NOT just for the Tag names.
Code
XmlDocument doc = new XmlDocument();
doc.LoadXml(xmlDoc.OuterXml.ToLower());
Original.xml
<?xml version="1.0" encoding="utf-8" ?>
<ROOT>
<InNeRtAg>SoMe TeXt</InNeRtAg>
<NeStEdElEmEnT>
<InNeRnEsTiNg>SoMe TeXt</InNeRnEsTiNg>
</NeStEdElEmEnT>
</ROOT>
Changing ALL nodes including the root element:
var doc = XDocument.Load("Original.xml");
// also need to change the root element
doc.Root.Name = doc.Root.Name.LocalName.ToLower();
foreach (var element in doc.Descendants().Elements())
{
element.Name = element.Name.LocalName.ToLower();
}
doc.Save("Modified.xml");
Results in Modified.xml
<?xml version="1.0" encoding="utf-8"?>
<root>
<innertag>SoMe TeXt</innertag>
<nestedelement>
<innernesting>SoMe TeXt</innernesting>
</nestedelement>
</root>
When using
foreach (var element in doc.Descendants().Elements())
{
element.Name = element.Name.LocalName.ToLower();
}
the root element will not be changed.
<?xml version="1.0" encoding="utf-8"?>
<ROOT>
<innertag>SoMe TeXt</innertag>
<nestedelement>
<innernesting>SoMe TeXt</innernesting>
</nestedelement>
</ROOT>
You can try something like this:
var doc = XDocument.Load(filepath);
foreach (var element in doc.Descendants().Elements())
{
element.Name = element.Name.LocalName.ToLower();
}
I am doing some practice code with the XmlTextReader. I have written some very basic XML as shown here:
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<task name="mixed_sprite_task_test">
<sprite>
<type>animatedSprite</type>
<id>0</id>
<name>animatedSprite</name>
<fileName>iyezoz</fileName>
<startingPositionX>200</startingPositionX>
<startingPositionY>200</startingPositionY>
<sheetSizeX>12</sheetSizeX>
<sheetSizeY>35</sheetSizeY>
<startingFrameX>0</startingFrameX>
<startingFrameY>0</startingFrameY>
<startingState>standing</startingState>
<movementSpeed>15</movementSpeed>
<frameDelay>0.055</frameDelay>
</sprite>
<sprite>
<type>staticSprite</type>
<id>0</id>
<name>staticSprite</name>
<fileName>Super_Mario_63</fileName>
<startingPositionX>0</startingPositionX>
<startingPositionY>0</startingPositionY>
</sprite>
<sprite>
<type>simpleSprite</type>
<id>0</id>
<name>simpleSprite</name>
<fileName>imgres</fileName>
<startingPositionX>100</startingPositionX>
<startingPositionY>100</startingPositionY>
<movementSpeed>15</movementSpeed>
</sprite>
</task>
This file shows that I have a task. In the task I have 3 sprites.
In my code I want to loop through each sprite and collect the information.
I can get the data from the first sprite with no issue. Is there a certain way to loop through an xml with attributes of the same name?
Thank-you!
I prefer Linq2Xml.
var xDoc = XDocument.Parse(xmlstring); //or XDocument.Load(filename);
var sprites = xDoc.Descendants("sprite")
.Select(s=>s.Elements()
.ToDictionary(e=>e.Name.LocalName,e=>(string)e))
.ToList();
You can use it as
var type = sprites[0]["type"];
or can take a safe action
string delay;
if (sprites[1].TryGetValue("frameDelay", out delay))
{
Console.WriteLine(delay);
}
You can select all the nodes named "sprite"
var myXml = new XmlDocument();
myXml.Load(myDocument);
XmlNode rootElement = myXml.DocumentElement;
foreach (XmlNode item in rootElement.SelectNodes(#"/task/sprite"))
{
// do stuff with node
}
Hi because of a misunderstanding I want to ask my question again.
I have the following XML structure:
<?xml version="1.0" encoding="utf-8"?>
<xml>
<root>
<Item>
<taxids>
<string>330</string>
<string>374</string>
<string>723</string>
<string>1087</string>
<string>1118</string>
<string>1121</string>
</taxids>
</Item>
</root>
</xml>
I need to get all the string nodes from the xml file to a string variable.
I want to get a string like this:
<taxids><string>330</string><string>374</string><string>723</string><string>1087</string><string>1118</string><string>1121</string></taxids>
My linq to xml:
var query = from ip in doc.XPathSelectElements("xml/root/Item")
select ip.XPathSelectElement("taxids").ToString();
But I am getting the following in one row of the variable query:
"System.Xml.XPath.XPathEvaluator+<EvaluateIterator>d__0`1[System.Xml.Linq.XElement]"
Is this possible?
Thanks!
Try this:
var result = doc.Element("xml")
.Element("root")
.Element("Item")
.Element("taxids")
.ToString(SaveOptions.DisableFormatting);
// result == "<taxids><string>330</string><string>374</string> ... </taxids>"
I'm getting the following block of xml back from a web service:
<?xml version="1.0" encoding="utf-16"?>
<ArrayOfItemResponse xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<ItemResponse>
<Item xmlns="http://www.xyz.com/ns/2006/05/01/webservices/abc/def">
<RequestKey Name="ESM.PA" Service="" />
<QoS>
<TimelinessInfo Timeliness="REALTIME" TimeInfo="0" />
<RateInfo Rate="TIME_CONFLATED" TimeInfo="10" />
</QoS>
<Status>
<StatusMsg>OK</StatusMsg>
<StatusCode>0</StatusCode>
</Status>
<Fields>
<Field DataType="Utf8String" Name="DSPLY_NAME">
<Utf8String>D15 |ASDFDSAA ETF </Utf8String>
</Field>
</Fields>
</Item>
</ItemResponse>
</ArrayOfItemResponse>
I'm trying to capture the Status element in an object as follows, but it's not working.
var _xml = XDocument.Parse(xmlFromService);
var stat = _xml
.Descendants("ArrayOfItemResponse")
.Descendants("ItemResponse")
.Descendants("Item")
.Descendants("Status");
What's the best way for me to get this element?
If you want to use System.Xml.Linq, you can use this expression:
var stat = (from n in _xml.Descendants() where n.Name.LocalName == "Status" select n).ToList();
You are not able to get the required results with your existing code because of the xmlns attribute in Item
<Item xmlns="http://www.xyz.com/ns/2006/05/01/webservices/abc/def">
This question addresses the problem you are actually facing. If you don't know the namespace then you should take a look at this question.
I don't know the best way, but you can read it like this
XmlDocument xdoc = new XmlDocument();
xdoc.Load(stream);
var statMsg = xdoc.GetElementsByTagName("StatusMsg")[0].InnerText;
var statCode = xdoc.GetElementsByTagName("StatusCode")[0].InnerText;
use xpath, something like
var stat = _xml.SelectSingleNode(#"ArrayOfItemResponse/ItemResponse/ItemStatus/StatusCode").Value;
that should put the value 0 into stat.
Your xml code use Namespace.
XNamespace ns = "http://www.xyz.com/ns/2006/05/01/webservices/abc/def";
var stat = _xml.Descendants(ns + "Status");
