I am adding a node to the XML file, but I need it to be properly formatted. Could you assist with it?
String newFile = System.IO.Path.GetFileName(textBox1.Text);
//file name
string filename = #"palette.xml";
XmlDocument doc = new XmlDocument();
doc.Load(filename);
//create node and add value
XmlNode node = doc.CreateNode(XmlNodeType.Element, "item", null);
//create title node
XmlNode nodeTitle = doc.CreateElement("name");
//add value for it
nodeTitle.InnerText = #"<![CDATA["+newFile+"]]>";
//create Url node
XmlNode nodeUrl = doc.CreateElement("imgfile");
nodeUrl.InnerText = newFile;
//add to parent node
node.AppendChild(nodeTitle);
node.AppendChild(nodeUrl);
//add to elements collection
doc.DocumentElement.AppendChild(node);
//save back
doc.Save(filename);
The XML should be looking like that:
<item>
<name><![CDATA[panda.gif]]></name>
<imgfile>panda.gif</imgfile>
</item>
but it look like that:
<item>
<name><![CDATA[panda.gif]]></name>
<imgfile>panda.gif</imgfile>
</item>
There is a method you can use to wrap cdata it is.
XMLNode.AppendChild( XMLDocument.CreateCDataSection( newFile ) );
It XMLDocument.CreateCDataSection returns XmlCDataSection object which you can append to your node and it will wrap your file in CDATA.
Check this out for more information: http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.createcdatasection.aspx
CDATA is considered a node, not an inner text
<item>
<name>
<![CDATA[panda.gif]]>
</name>
<imgfile>panda.gif</imgfile>
</item>
So:
XmlElement nodeTitle = document.CreateElement("name");
XmlCDataSection CDATA = document.CreateCDataSection("panda.gif");
nodeTitle.AppendChild(CDATA);
node.AppendChild(nodeTitle);

I have XML response from service and I need to get value of tag that exist in child node that this child node is a child node.
For example: This is an example of xml.
<ashrait>
<response>
<command>inquire</command>
<inquire>
<row>
<ResponseCode>000</ResponseCode>
<ResponseText>
Permitted.
</ResponseText>
<ResponseXML>
<ashrait>
<response>
<message>Permitted .</message>
<userMessage>Permitted .</userMessage>
</response>
</ashrait>
</ResponseXML>
</row>
</inquire>
</response>
</ashrait>
I need the the value in tag "userMessage" that exists in tag "ResponseXML".
I know that to get the node of "ResponseXML" I need for those lines:
var doc = new XmlDocument();
doc.LoadXml(responseFile);
ChildNode result = doc.GetElementsByTagName("ResponseXML")[0];
But how i get the tag userMessage in childNode "ResponseXML"?
Thanks
UPDATE:
I figured out how to do it.
Search for all the children with the tag and choose the order they want.
Create a model for your XML, load that model using XmlSerializer.
Check this Microsoft Docs.
https://learn.microsoft.com/en-us/dotnet/standard/serialization/examples-of-xml-serialization
Use
SelectNodes method: https://msdn.microsoft.com/en-us/library/hcebdtae(v=vs.110).aspx
or SelectSingleNode method: https://msdn.microsoft.com/en-us/library/system.xml.xmlnode.selectsinglenode(v=vs.110).aspx
var doc = new XmlDocument();
doc.LoadXml(Xml);
XmlNode xn = doc.SelectSingleNode("//ashrait//inquire//row//ResponseXML//message");
var innerText = xn.InnerText;
I have an XmlNode which represents the following xml for example:
XmlNode xml.innerText =
<book>
<name><![CDATA[Harry Potter]]</name>
<author><![CDATA[J.K. Rolling]]</author>
</book>
I want to change this node so that it'll contain the following:
XmlNode xml.innerText =
<book>
<name>Harry Potter</name>
<author>J.K. Rolling</author>
</book>
Any ideas?Thanks!
well, if it's exactly how you put it, then it's easy:
xml.innerText = xml.innerText.Replace("![CDATA[","").Replace("]]","");
xmlDoc.Save();// xmlDoc is your xml document
I suggest you to read your entire xml and rewrite it. You can read values without cdata like this
foreach (var child in doc.Root.Elements())
{
string name = child.Name;
string value = child.Value
}
I don't how to extract the values from XML document, and am looking for some help as I'm new to C#
I am using XmlDocument and then XmlNodeList for fetching the particular XML document
Here is my code
XmlNodeList XMLList = doc.SelectNodes("/response/result/doc");
And my XML looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<response>
<result>
<doc>
<long name="LoadID">494</long>
<long name="EventID">5557</long>
<str name="XMLData"><TransactionDate>2014-05-28T14:17:31.2186777-06:00</TransactionDate><SubType>tblQM2222Components</SubType><IntegerValue title="ComponentID">11111</IntegerValue></str></doc>
<doc>
<long name="LoadID">774</long>
<long name="EventID">5558</long>
<str name="XMLData"><TransactionDate>2014-05-28T14:17:31.2186777-06:00</TransactionDate><SubType>tblQM2222Components</SubType><IntegerValue title="ComponentID">11111</IntegerValue></str></doc>
</result>
</response>
In this i have to fetch every the XMLData data that is under every doc tag and i have to fetch last doc tag EventID.
var xml = XDocument.Parse(xmlString);
var docs = xml.Root.Elements("doc");
var lastDocEventID = docs.Last()
.Elements("long")
.First(l => (string)l.Attribute("name") == "EventID")
.Value;
Console.WriteLine ("Last doc EventId: " +lastDocEventID);
foreach (var doc in docs)
{
Console.WriteLine (doc.Element("str").Element("TransactionDate").Value);
}
prints:
Last doc EventId: 5558
2014-05-28T14:17:31.2186777-06:00
2014-05-28T14:17:31.2186777-06:00
You can use two XPath expressions to select the nodes you want. To answer each part of your question in turn:
To select all of the XMLData nodes:
XmlNodeList XMLList
= doc.SelectNodes("/response/result/doc/str[#name='XMLData']");
To select the last EventId:
XmlNode lastEventIdNode =
doc.SelectSingleNode("/response/result/doc[position() =
last()]/long[#name='EventID']");
If not all doc nodes are guaranteed to have an event id child node, then you can simply:
XmlNodeList eventIdNodes =
doc.SelectNodes("/response/result/doc[long[#name='EventID']]");
XmlNode lastNode = eventIdNodes[eventIdNodes.Count - 1];
That should give you what you've asked for.
Update;
If you want the XML data inside each strXml element, you can use the InnerXml property:
XmlNodeList xmlList
= doc.SelectNodes("/response/result/doc/str[#name='XMLData']");
foreach(XmlNode xmlStrNode in xmlList)
{
string xmlInner = xmlStrNode.InnerXml;
}
There's one result tag short in your xml.
Try using this. It's cleaner too imho
XmlNodeList docs = doc.SelectSingleNode("response").SelectSingleNode("result").SelectNodes("doc");
Then you can use a combination of SelectSingleNode, InnerText, Value to get the data from each XmlNode in your list.
For example if you want the EventID from the first doc tag:
int eventID = int.Parse(docs[0].SelectSingleNode("long[#name='EventID']").InnerText);
I need to create an XmlDocument partly by using old XML and partly by creating new. The problem is that the old XML contains custom namespaces and I can't seem to be able to use them as I get an XmlException. I've tried to add the namespace to many different places but I can't get over the Exception!
The Exception
System.Xml.XmlException was unhandled by user code
Message='my' is an undeclared prefix. Line 1, position 42.
Source=System.Xml
My Code
XmlDocument doc = new XmlDocument();
XmlSchema schema = new XmlSchema();
schema.Namespaces.Add("my", "http://foobar.com/");
doc.Schemas.Add(schema);
XmlDeclaration dec = doc.CreateXmlDeclaration("1.0", "UTF-8", null);
doc.AppendChild(dec);
XmlElement root = doc.CreateElement("root");
root.SetAttribute("xmlns:my", "http://foobar.com/");
doc.AppendChild(root);
foreach (var item in GetItems())
{
XmlElement elem = doc.CreateElement("item");
elem.SetAttribute("id", item.id);
// Append body to elem
XmlElement body = doc.CreateElement("body");
body.InnerXml = item.Body; // Here is where I get the exception
elem.AppendChild(body);
// Append elem to root
root.AppendChild(elem);
}
Input from Item.Body is similar to
<aaa><bbb my:attr="55">Foo</bbb></aaa>
I expected the output to be similar to
<?xml version="1.0" encoding="utf-8"?>
<root my:attr="http://foobar.com/">
<item id="12345">
<body>
<aaa>
<bbb my:attr="55">Foo</bbb>
</aaa>
</body>
</item>
</root>
I'm open to alternatives to using this method. After I create the XmlDocument I prettyprint it, validate it against a schema and then push it out for the user to see.
The following is a workaround, best I can come up with:
XNamespace my = "http://foobar.com/";
var doc = new XDocument(new XElement("root",
new XAttribute(XNamespace.Xmlns + "my", my)));
var body = new XElement("body");
doc.Root.Add(new XElement("item", new XAttribute("id", 12345), body));
string innerItem = #"<aaa><bbb my:attr=""55"">Foo</bbb></aaa>";
string itemWrap = #"<wrap xmlns:my=""http://foobar.com/"">" + innerItem + "</wrap>";
XElement item = XElement.Parse(itemWrap);
body.Add(item.Element("aaa"));
Console.WriteLine(doc);
I'm navigating XML document with XPathNodeIterator, and I want to change some nodes' values.
I can't figure out how :(
Here's the code I'm using:
XPathDocument docNav = new XPathDocument(path);
XPathNavigator nav = docNav.CreateNavigator();
nav.MoveToRoot();
XPathNodeIterator itemsIterator = nav.Select("/foo/bar/item");
while (mediumsIterator.MoveNext())
{
XPathNodeIterator subitemsIterator = itemsIterator.Current.Select("SubitemsList/name");
while (subitemsIterator.MoveNext())
{
XPathNodeIterator nodesIterator = itemsIterator.Current.Select("Param");
nodesIterator.MoveNext();
String the_params = nodesIterator.Current.Value;
// check if I need to modify nodesIterator.Current.Value
// ...
// ok I do - how?
}
}
And the XML file sample:
<?xml version="1.0" encoding="utf-8"?>
<foo>
<bar>
<item>
<Param />
<SubitemsList>
<name>name one</name>
<name>name two</name>
...
</SubitemsList>
</item>
...
</bar>
</foo>
Or maybe there's a better way to do this?
I found a way:
Replace XPathDocument with XmlDocument
When I get to the needed node
...
XmlNode node = ((IHasXmlNode)nodesIterator.Current).GetNode();
node.InnerText = "new text";
