XElement ReplaceWith

I would like to replace a specific node with string.
It successfully replace the node but instead of "<div>", it appear "<div>"
What should I do to make it into "<div>"?
I have tried XElement.Parse but it will give me error as I replace node with "</div><div>"
foreach (var node in Nodes)
{
var newElement = XElement.Parse("</div><div>");
node.ReplaceWith(sbb.ToString);
}

Use the following
XElement foo = XElement.Parse("<div>example</div>");
foo.ReplaceNodes(XElement.Parse("<div>" + otherMarkUp + "</div>").Nodes());
Based on your code, you should replace with the newElement.
foreach (var node in Nodes)
{
var newElement = XElement.Parse("<div></div>");
node.ReplaceWith(newElement);
}
If the above does not work, please share some more code to work on it.

XDocument, it says that a node is text but it is an element

I am reading an XML that contains a tag like this:
<source><bpt id="1"><donottranslate></bpt><ph id="2">($ T_353_1 Parent ID $)</ph><ept id="1"></donottranslate></ept></source>
When reading source node I get that this node type is Text, but it should be Element.
This is an XML that I am receiving and I cannot change it.
Do you know how can I get this sorted out?
This is my code:
XDocument doc = XDocument.Load(fileName, LoadOptions.PreserveWhitespace);
foreach (var elUnit in doc.Descendants("trans-unit"))
{
if (elUnit.AttributeString("translate").ToString() == "no")
{
foreach (var elSource in elUnit.Elements("source"))
{
string text = "";
foreach (var node in elSource.DescendantNodes().Where(n => XmlNodeType.Text == n.NodeType).ToList())
{
//When reading that "source" node, it enters inside this code
Thanks

First check whether your XML is wellformed
http://www.w3schools.com/xml/xml_validator.asp
http://chris.photobooks.com/xml/default.htm
I could get this to work
//using System.Xml.Linq;
var str = "<source><bpt id=\"1\"><donottranslate></bpt>" +
"<ph id=\"2\">($ T_353_1 Parent ID $)</ph>" +
"<ept id=\"1\"></donottranslate></ept></source>";
XElement element = XElement.Parse(str);
Console.WriteLine(element);
The output is this
<source>
<bpt id="1"><donottranslate></bpt>
<ph id="2">($ T_353_1 Parent ID $)</ph>
<ept id="1"></donottranslate></ept>
</source>
Please provide some code sample for more help if this example if not suffient.

Finally, I solved this checking if the node is correct or not:
if (System.Security.SecurityElement.IsValidText(text.XmlDecodeEntities()))

How to iterate a xml file with XmlReader class

my xml stored in xml file which look like as below
<?xml version="1.0" encoding="utf-8"?>
<metroStyleManager>
<Style>Blue</Style>
<Theme>Dark</Theme>
<Owner>CSRAssistant.Form1, Text: CSR Assistant</Owner>
<Site>System.ComponentModel.Container+Site</Site>
<Container>System.ComponentModel.Container</Container>
</metroStyleManager>
this way i am iterating but some glitch is there
XmlReader rdr = XmlReader.Create(System.IO.Path.GetDirectoryName(System.Windows.Forms.Application.ExecutablePath) + #"\Products.xml");
while (rdr.Read())
{
if (rdr.NodeType == XmlNodeType.Element)
{
string xx1= rdr.LocalName;
string xx = rdr.Value;
}
}
it is always getting empty string xx = rdr.Value;
when element is style then value should be Blue as in the file but i am getting always empty....can u say why?
another requirement is i want to iterate always within <metroStyleManager></metroStyleManager>
can anyone help for the above two points. thanks

Blue is the value of Text node, not of Element node. You either need to add another if to get value of text nodes, or you can read inner xml of current element node:
rdr.MoveToContent();
while (rdr.Read())
{
if (rdr.NodeType == XmlNodeType.Element)
{
string name = rdr.LocalName;
string value = rdr.ReadInnerXml();
}
}
You can also use Linq to Xml to get names and values of root children:
var xdoc = XDocument.Load(path_to_xml);
var query = from e in xdoc.Root.Elements()
select new {
e.Name.LocalName,
Value = (string)e
};

You can use the XmlDocument class for this.
XmlDocument doc = new XmlDocument.Load(filename);
foreach (XmlNode node in doc.ChildNodes)
{
if (node.ElementName == "metroStyleManager")
{
foreach (XmlNode subNode in node.ChildNodes)
{
string key = subNode.LocalName; // Style, Theme, etc.
string value = subNode.Value; // Blue, Dark, etc.
}
}
else
{
...
}
}

you can user XDocument xDoc = XDocument.Load(strFilePath) to load XML file.
then you can use
foreach (XElement xeNode in xDoc.Element("metroStyleManager").Elements())
{
//Check if node exist
if (!xeNode.Elements("Style").Any()
//If yes then
xeNode.Value
}
Hope it Helps...
BTW, its from System.XML.Linq.XDocument

Query to remove last result using LINQ to XML

I am having trouble parsing an xml file . A sample is below.
<G_LOG>
<LINE>9206</LINE>
<TEXT>Generating
</TEXT>
</G_LOG>
<G_LOG>
<LINE>9207</LINE>
<TEXT>Inserted Actual
</TEXT>
O.K , so this is just a snapshot of thousands of nodes in the file. I need to search for the TEXT "Inserted Actual" and not only remove this node , but the previous node as well. So it would find the text on line 9207 and remove 9206 as well. (removing everything in the above snippet)
I can search for the lines I want to remove .
XDocument xmlDoc = XDocument.Load(filename);
var q = from c in xmlDoc.Descendants("G_LOG")
where c.Element("TEXT").Value.Contains("Inserted Actual")
select (string)c.Element("LINE");
foreach (string name in q)
{
Console.WriteLine("Actuals Success on ID : " + name);
}
But I am unsure of how to obtain the previous node and remove it as well (without buckets of code)?.

var elementsToRemove =
from logElement in xml.Descendants("G_LOG")
where logElement.Element("TEXT").Value.Contains("Inserted Actual")
from element in new[] { logElement, logElement.PreviousNode }
select element;
foreach(var element in elementsToRemove.ToList())
{
element.Remove();
}
A couple of things to note:
The second from flattens out each node and its previous node into one sequence
The .ToList() eagerly evaluates the query, ensuring we don't remove a node while evaluating

XElement xmlDoc = XElement.Load("c:\\temp.xml");
var q = xmlDoc.Descendants("G_LOG").Where(c=>c.Element("TEXT").Value.Contains("Inserted Actual")).Select(d=>d.Element("LINE"));
foreach(XElement elm in q)
{
if(elm.Parent.ElementsBeforeSelf().Count()!=0)
elm.Parent.PreviousNode.Remove();
elm.Parent.RemoveNodes();
}

how to read value from XML?

The data:
<sys>
<id>SCPUCLK</id>
<label>CPU Clock</label>
<value>2930</value>
</sys>
<sys>
<id>CPUTEMP</id>
<label>CPU Temp</label>
<value>39</value>
</sys>
This is the code that I'm using to read the data:
XmlDocument document = new XmlDocument();
document.LoadXml(data);
XmlElement node = document.SelectSingleNode("/sys/value") as XmlElement;
Console.WriteLine("node = " + node);
The issue: Console.WriteLine("node = " + node); doesn't give me any output besides node: but no actual value like 2930 from the sample above.
Thanks

use node.value ie., XmlElement.value

As an alternative to using XmlDocument, you can also use LINQ to XML (which is my preference):
using System.Xml.Linq;
XDocument xDoc = new XDocument();
// Parse loads the XDocument with XML from a string
xDoc = XDocument.Parse(data);
string node = (from x in xDoc.Root.Elements("value")
select x.Value).SingleOrDefault();
Console.WriteLine("node = " + node);
Nothing wrong with using XmlDocument, especially for what you're doing, but you might want to check out LINQ to XML when you get a chance, as I find it a lot easier to work with than XmlDocument.
If you want to get all the "value" elements, simply remove the SingleOrDefault() from the query, and then you can loop through the result, like this:
var nodes = from x in xDoc.Root.Elements("value")
select x.Value;
foreach (var node in nodes)
{
Console.WriteLine("node = " + node);
}
