I am trying to loop through an Xml file and display the value for account in a message.
XmlNodeList nodeList = testDoc.SelectNodes("/details/row/var");
foreach (XmlNode no in nodeList)
{
XmlNode node = testDoc.SelectSingleNode("/details/row/var[#name='account']");
test.actual = node.Attributes["value"].Value;
MessageBox.Show(test.account);
}
The message box is currently displaying the first record repeatidly, how can I get to the next record?
Thanks for your input in advance.
You are repeatedly assigning node with the same element from testDoc. It is not clear what test.account is (perhaps a mistype for test.actual)?
no is the variable which will iterate the contents of nodeList - I imagine you intended to use that.
EDIT following edit of OP
Now you've shown us what nodeList is, I suspect you want to do something like this instead :
XmlNodeList nodeList = testDoc.SelectNodes("/details/row/var[#name='account']");
foreach (XmlNode no in nodeList)
{
test.actual = no.Attributes["value"].Value;
...
XmlDocument doc = new XmlDocument();
doc.Load("d:\\test.xml");
XmlNodeList node = doc.GetElementsByTagName("w:r");
foreach (XmlNode xn in node)
{
try
{
if (xn["w:t"].InnerText != null)
{
if (xn["w:t"].InnerText == "#")
{
string placeHolder = xn["w:t"].InnerText;
foreach (XmlNode a in node)
{
if (a["w:t"].InnerText != "#")
{
string placeHolder1 = a["w:t"].InnerText;
}
}
}
}
}
catch (Exception e)
{
Console.Write(e);
}
}
Here is the sample for parent node value to get information of the child nodes.here i am using the ReportItems ParentNode and Print only image child nodes.
xmldoc.Load(rdlFile);
StringBuilder sb=new StringBuilder();
XmlNode node = xmldoc.GetElementsByTagName("ReportItems")[0];
XmlNodeList list = node.ChildNodes;
atributes=new string[node.ChildNodes.Count];
int l = 0;
for (int j = 0; j < node.ChildNodes.Count; j++)
{
if (list[j].Name == "Image")
{
XmlAttributeCollection att = list[j].Attributes;
atributes[l] = att[0].Value.ToUpper();
}
l++;
}
for (int i = 0; i < node.ChildNodes.Count; i++)
{
if (searchText.Text.ToUpper() == atributes[i])
{
XmlNodeList lastlist = node.ChildNodes;
XmlNodeList endlist = lastlist[i].ChildNodes;
for (int k = 0; k < endlist.Count; k++)
{
sb.Append(endlist[k].Name+" - "+ endlist[k].InnerText);
sb.Append("\n"+"\n");
}
}
}
let me know if you have doubt..
Try this,
XmlDocument xdoc = new XDocument();
xdoc.Load("*/File/*");
string xmlcontents = xdoc.InnerXml;
var xpath = "(/details/row/var[#name='account'])";
XmlNodeList lists = xdoc.DocumentElement.SelectNodes(xpath);
foreach (XmlNode _node in lists)
{
string _nodeValue = _node.InnerText;
MessageBox.Show(_nodeValue);
}
Try the following:
//Create an xml reader;
XmlDocument _xmlDocument = new XmlDocument();
_xmlDocument.Load(/*File Name here*/);
//Select the element with in the xml you wish to extract;
XmlNodeList _nodeList = _xmlDocument.SelectNodes("/details/row/var[#name='account']");
//Display the values in the node list to the screen;
foreach (XmlNode _node in _nodeList)
{
String _nodeValue = _node.InnerText.ToString();
MessageBox.Show(_nodeValue.ToString());
}
I'm not 100% sure, but you may need to use recursion. If not, it should just look like this:
XmlDocument doc = //etc..
foreach(XmlNode node in doc.ChildNodes)
{
if(node.Name == "account")
{
MessageBox.Show(node.Value);
}
}
You shouldn't spend time with reading the xml node by node. Try Deserialization:

I have an XML file looking like this:
<data xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<row>
<Alert>warning</Alert>
<Alert2>warning</Alert2>
</row>
</data>
When I use the code below I only get the "Alert"-node. But I wan't "Alert2" as well (and so on...). What am I missing here?
using (XmlReader reader = cmd.ExecuteXmlReader())
{
string xmlFile = "";
while (reader.Read())
{
xmlFile = reader.ReadOuterXml();
}
var doc = new XmlDocument();
doc.LoadXml(xmlFile);
var nodes = doc.SelectNodes("data/row");
if (nodes == null) return columns;
var i = 0;
foreach (XmlNode node in nodes)
{
var column = node.ChildNodes[i].Name;
columns.Add(column);
i++;
}
return columns;
}
Change your loop to the equivalent of:
var doc = new XmlDocument();
doc.LoadXml(xml);
var nodes = doc.SelectNodes("data/row");
int i = 0;
foreach (XmlNode node in nodes)
{
foreach (var child in node.ChildNodes)
{
var element = (XmlElement)child;
string nodeName = element.Name;
string value = element.InnerXml;
i++;
}
}
I have data in the following format:
https://www.dropbox.com/s/osu4w634lnoy2pw/2.xml
While trying to parse I want all the field elements also. I am able to get all the elements under table but not under field. Could somebody please help me?
My code is as follows:
XmlDocument doc = new XmlDocument();
doc.Load(#maploc);
XmlNodeList nodes = doc.DocumentElement.SelectNodes("/schema/table");
foreach (XmlNode node in nodes)
{
attribute1 = "";
attribute2 = "";
attribute3 = "";
try
{
attribute1 = node.Attributes["name"].Value;
attribute2 = node.SelectSingleNode("tabledefault").InnerText;
attribute3 = node.SelectSingleNode("invoke").InnerText;
}
catch(Exception ex)
{
//Nothing
}
if (node.HasChildNodes)
{
for (int i = 0; i < node.ChildNodes.Count; i++)
{
foreach (XmlNode nodei in node.ChildNodes[i])
{
attribute4 = "";
attribute5 = "";
attribute6 = "";
try
{
attribute4 = node.Attributes["name"].Value;
attribute5 = node.SelectSingleNode("invoke").InnerText;
attribute6 = node.SelectSingleNode("dtype").InnerText;
catch (Exception ex)
{
//Nothing
}
}
}
}
Thanks...
Your error is :
for (int i = 0; i < node.ChildNodes.Count; i++)
{
foreach (XmlNode nodei in node.ChildNodes[i])
{
You are iterating over the nodes that are the children of the current child (you are going one level too deep). This is because an XmlNode is an Enumerable over its Children.
A single foreach loop is needed :
foreach (XmlNode nodei in node.ChildNodes)
{
I need to store the element values which are inside the nodes "member" . I have tried the following code but I can't achieve it. How to get the values. Any help would be appreciated
XML:
<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">
<ListInventorySupplyResult>
<InventorySupplyList>
<member>
<SellerSKU>043859634910</SellerSKU>
<FNSKU>X000IA4045</FNSKU>
<ASIN>B005YV4DJO</ASIN>
<Condition>NewItem</Condition>
<TotalSupplyQuantity>7</TotalSupplyQuantity>
<InStockSupplyQuantity>7</InStockSupplyQuantity>
<EarliestAvailability>
<TimepointType>Immediately</TimepointType>
</EarliestAvailability>
<SupplyDetail>
</SupplyDetail>
</member>
</InventorySupplyList>
</ListInventorySupplyResult>
<ResponseMetadata>
<RequestId>58c9f4f4-6f60-496a-8d71-8fe99ce301c9</RequestId>
</ResponseMetadata>
</ListInventorySupplyResponse>
C# Code:
string a = Convert.ToString(oInventorySupplyRes.ToXML());
XmlDocument oXdoc = new XmlDocument();
oXdoc.LoadXml(a);
XmlNodeList oInventorySupplyListxml = oXdoc.SelectNodes("//member");
foreach (XmlNode itmXml in oInventorySupplyListxml)
{
// var cond = itmXml.InnerXml.ToString();
var asinVal = itmXml.SelectSingleNode("ASIN").Value;
var TotalSupplyQuantityVal = itmXml.SelectSingleNode("TotalSupplyQuantity").Value;
}
ResultView : "Enumeration yielded no results" and count = 0;
Edit 1:
string a = Convert.ToString(oInventorySupplyRes.ToXML());
var status = oInventorySupplyResult.InventorySupplyList;
XmlDocument oXdoc = new XmlDocument();
var doc = XDocument.Parse(a);
var r = doc.Descendants("member")
.Select(member => new
{
ASIN = member.Element("ASIN").Value,
TotalSupplyQuantity = member.Element("TotalSupplyQuantity").Value
});
private string mStrXMLStk = Application.StartupPath + "\\Path.xml";
private System.Xml.XmlDocument mXDoc = new XmlDocument();
mXDoc.Load(mStrXMLStk);
XmlNode XNode = mXDoc.SelectSingleNode("/ListInventorySupplyResult/InventorySupplyList/member");
if (XNode != null)
{
int IntChildCount = XNode.ChildNodes.Count;
for (int IntI = 1; IntI <= IntChildCount ; IntI++)
{
string LocalName = XNode.ChildNodes[IntI].LocalName;
XmlNode Node = mXDoc.SelectSingleNode("/Response/" + LocalName);
// Store Value in Array assign value by "Node.InnerText"
}
}
Try This Code. Its Worked
try using this xpath
string xPath ="ListInventorySupplyResponse/ListInventorySupplyResult
/InventorySupplyList/member"
XmlNodeList oInventorySupplyListxml = oXdoc.SelectNodes(xpath);
when you do "//member", then, the code is trying to look for element named member from the root level, which is not present at the root level, rather it is nested beneath few layers.
I think this will help you..
string a = Convert.ToString(oInventorySupplyRes.ToXML());
XmlDocument oXdoc = new XmlDocument();
oXdoc.LoadXml(a);
XmlNodeList fromselectors;
XmlNodeList toselectors;
XmlElement root = oXdoc.DocumentElement;
fromselectors = root.SelectNodes("ListInventorySupplyResult/InventorySupplyList/member/ASIN");
toselectors = root.SelectNodes("ListInventorySupplyResult/InventorySupplyList/member/TotalSupplyQuantity");
foreach (XmlNode m in fromselectors)
{
you will have value in `m.InnerXml` use it whereever you want..
}
foreach (XmlNode n in toselectors)
{
you will have value in `n.InnerXml` use it whereever you want..
}
I have this XML

I read with this C# code :
private void leerarquivoN(string caminx)
{
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(caminx);
XmlNodeList ml = xmlDoc.GetElementsByTagName("*");
XmlNode primer = xmlDoc.DocumentElement;
tipo_arq = primer.Name;
if (xmlDoc.DocumentElement.Name == "nfeProc")
{ foreach (XmlNode xn in ml)

{
chave_nota = xn.Attributes["Id"].Value;
versao = xn.Attributes["versao"].Value;
lblChaveNota.Text = chave_nota; lblversao.Text = versao;
}
}
XmlNodeList xnList = xmlDoc.GetElementsByTagName("ide");
foreach (XmlNode xn in xnList)

if (xn.Name == "ide")
{

{ ndata = (xn["dEmi"]).InnerText; lblData.Text = ndata;}
if (xn["natOP"] != null)
{ natop = (xn["natOP"]).InnerText; lblNAtop.Text = natop ; }
}
}
XmlNodeList xnList2 = xmlDoc.GetElementsByTagName("emit");
foreach (XmlNode xn in xnList2)
{
{ if (xn["CNPJ"] != null)

foreach (XmlNode xn in xnList3)

{ ntotal = (xn["vNF"]).InnerText; lblvNF.Text = ntotal ; }
}
}
}
I can not read VNF and natOP , what i m doing wrong???
Thanks
The code you are using just gets the main nodes. To get the children associated with each node (natOp and vNF), you have to rely on a different code (MSDN reference). Sample for natOp (inside the xnList for loop):
if (xn.HasChildNodes)
{
for (int i=0; i<xn.ChildNodes.Count; i++)
{
//xn.ChildNodes[i].InnerText -> what you are after
}
}
I need to remove elements in some xml files. How do I correctly ensure that I transverse through all childnodes to remove all element with a matching name. I have code such as:
string strFilename = #"D:\sample.xml";
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(strFilename);
XmlNode parentNode;
parentNode = xmlDoc.DocumentElement;
foreach (XmlNode node1 in parentNode.ChildNodes)
{
foreach (XmlNode node2 in node1.ChildNodes)
{
if (node2.Name == "ElementNodeToDelete")
{
node2.ParentNode.RemoveChild(node2);
}
foreach (XmlNode node3 in node2.ChildNodes)
{
if (node3.Name == "ElementNodeToDelete")
{
node3.ParentNode.RemoveChild(node3);
}
foreach (XmlNode node4 in node3.ChildNodes)
{
if (node4.Name == "ElementNodeToDelete")
{
node4.ParentNode.RemoveChild(node4);
}
}
}
}
}
Is this a valid solution? How do I determine how many foreach loops to perform to ensure that all children are checked?
Thanks for your time in advance.
Recursion is your friend.
void DeleteNodes(XmlNode root, string deleteName)
{
foreach(XmlNode node in root.ChildNodes)
{
if (node.Name == deleteName)
{
root.RemoveChild(node);
}
else
{
DeleteNodes(node,deleteName);
}
}
}
