Get xml element with specific attribute value in XmlDocument - c#

Based on the XML below:
<?xml version="1.0" encoding="Windows-1252"?>
<ConfData>
<CfgAgentGroup>
<CfgGroup>
<DBID value="109" />
<tenantDBID value="1" />
<name value="group1" />
<contractDBID value="0" />
</CfgGroup>
<agentDBIDs>
<DBID value="103" />
<DBID value="994" />
</agentDBIDs>
</CfgAgentGroup>
<CfgAgentGroup>
<CfgGroup>
<DBID value="110" />
<tenantDBID value="1" />
<name value="group2" />
<contractDBID value="0" />
</CfgGroup>
<agentDBIDs>
<DBID value="102" />
<DBID value="103" />
<DBID value="1019" />
<DBID value="1020" />
</agentDBIDs>
</CfgAgentGroup>
</ConfData>
How can I get the <CfgGroup> element if the attribute value is 103 (referring to agentDBIDs/DBID value, NOT CfgGroup/DBID value)?
Any suggestions?

You can use SelectNodes() passing the following XPath as parameter to pull out CfgGroup elements where the corresponding agentDBIDs/DBID/#value equals 103, from an XmlDocument :
/ConfData/CfgAgentGroup[agentDBIDs/DBID/#value=103]/CfgGroup
working demo example :
var xml = #"<ConfData>
<CfgAgentGroup>
<CfgGroup>
<DBID value='109' />
<tenantDBID value='1' />
<name value='group1' />
<contractDBID value='0' />
</CfgGroup>
<agentDBIDs>
<DBID value='103' />
<DBID value='994' />
</agentDBIDs>
</CfgAgentGroup>
<CfgAgentGroup>
<CfgGroup>
<DBID value='110' />
<tenantDBID value='1' />
<name value='group2' />
<contractDBID value='0' />
</CfgGroup>
<agentDBIDs>
<DBID value='102' />
<DBID value='103' />
<DBID value='1019' />
<DBID value='1020' />
</agentDBIDs>
</CfgAgentGroup>
</ConfData>";
var doc = new XmlDocument();
doc.LoadXml(xml);
var result = doc.DocumentElement.SelectNodes("/ConfData/CfgAgentGroup[agentDBIDs/DBID/#value=103]/CfgGroup");
foreach(XmlNode r in result)
{
Console.WriteLine(r.OuterXml);
}
Dotnetfiddle Demo
output :
<CfgGroup><DBID value="109" /><tenantDBID value="1" /><name value="group1" /><contractDBID value="0" /></CfgGroup>
<CfgGroup><DBID value="110" /><tenantDBID value="1" /><name value="group2" /><contractDBID value="0" /></CfgGroup>

If I understood your question correctly, this should do
var xDoc = XDocument.Parse(File.ReadAllText(#"C:\YourDirectory\sample.xml"));
var cfgAgentGroups = xDoc.Descendants("CfgAgentGroup");
var cfgGroups = cfgAgentGroups
.Where(n => n.Element("agentDBIDs")
.Elements("DBID")
.Any(dbid => dbid.Attribute("value").Value == "103"))
.Select(cag => cag.Element("CfgGroup"));

Try this
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication1
{
class Program
{
const string FILENAME = #"c:\temp\test.xml";
static void Main(string[] args)
{
XDocument doc = XDocument.Load(FILENAME);
XElement CfgAgentGroup = doc.Descendants("CfgAgentGroup").Where(x => (int)x.Element("agentDBIDs").Element("DBID").Attribute("value") == 103).FirstOrDefault();
XElement cfgGroup = CfgAgentGroup.Element("CfgGroup");
}
}
}

THis is exactly the XML that i receive and that's the envelope that i will have to create (Request generated by SOAPUI),the nodes will have dynamic Values of course, those parameteres were just an example.
i assume this is the easiest way since i can't "add service reference" because i am trying to develop a DLL where the webservices will be nested. There's no web.config where this DLL is going to be installed.
Thank you soo much for helping me with the logic for this problem that is driving me crazy

C# Removing attribute XML

I am trying to remove some specified attributed from the XML file sample code was below. string[] szNodeList is the array list so node contains name in string array will be removed ans save again
Any help will be appreciated.
var doc = new System.Xml.XmlDocument();
doc.Load("attrs.xml");
var root = doc.DocumentElement;
string[] szNodeList = new string[] { "titleTextColor"
,"isLightTheme"
,"showText"
};
foreach (System.Xml.XmlElement child in root )
{
foreach (string sz in szNodeList)
{
root.RemoveAttribute(sz);
//if (child.Attributes[sz] != null)
//{
// child.Attributes.Remove(child.Attributes[sz]);
//}
}
}
doc.Save("build.xml");
XML CODE
<?xml version="1.0" encoding="utf-8"?>
<resources>
<attr name="cropImageStyle" format="reference" />
<attr name="drawerArrowStyle" format="reference" />
<attr name="height" format="dimension" />
<attr name="isLightTheme" format="boolean" />
<attr name="title" format="string" />
<attr name="navigationMode">
<enum name="listMode" value="1" />
<enum name="normal" value="0" />
<enum name="tabMode" value="2" />
</attr>
</resources>
But saving as original file without changes i thing remove is not working.
Try this:
doc
// select all `resources/attr` node
.SelectNodes("resources/attr")
.Cast<XmlNode>()
// that contains the `name` attribute whose value is in `szNodeList`
.Where(x => !string.IsNullOrEmpty(x.Attributes["name"]?.Value) && szNodeList.Contains(x.Attributes["name"].Value))
.ToList()
// and, remove them from their parent
.ForEach(x => x.ParentNode.RemoveChild(x));
One of the problems here is terminology. You're not trying to remove attributes, as I understand it - you're trying to remove whole elements, based on the value of the name attribute.
If you can possibly use LINQ to XML for this, I would do so. It generally makes working with XML a lot easier. Here's a complete program to do what you want:
using System;
using System.Linq;
using System.Xml.Linq;
class Test
{
static void Main()
{
var namesToRemove = new[]
{
"titleTextColor",
"isLightTheme",
"showText"
};
XDocument doc = XDocument.Load("test.xml");
// For all the elements directly under the document root...
doc.Root.Elements()
// Where the array contains the value of the "name" attribute...
.Where(x => namesToRemove.Contains((string) x.Attribute("name")))
// Remove them from the document
.Remove();
doc.Save("output.xml");
}
}
Output:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<attr name="cropImageStyle" format="reference" />
<attr name="drawerArrowStyle" format="reference" />
<attr name="height" format="dimension" />
<attr name="title" format="string" />
<attr name="navigationMode">
<enum name="listMode" value="1" />
<enum name="normal" value="0" />
<enum name="tabMode" value="2" />
</attr>
</resources>

and I wants to read/get the data from position and value and wants to store that data into the respective ArrayList but don't know how to do it. Please help
Dnyanesh.
To read XML-files you can use System.Xml inluded to .NET Framework.
It works a kind of this:
using System.Xml;
...
XmlDocument MyXmlFile = new XmlDocument();
MyXmlFile.LoadXml(PATH_TO_MY_XML);
// Using
XmlNode xmlValueItem = MyXmlFile.GetElementsByTagName("ValueItem")[0];
string position = xmlValueItem.Attributes["Position"].InnerText;
Google for System.Xml and XPath to work with XML documents.
protected void Page_Load(object sender, EventArgs e)
{
DataSet ds = new DataSet();
ds.ReadXml(Server.MapPath("~/Record7.xml"));
XmlDocument xmldoc = new XmlDocument();
Record.DataSource = ds;
Record.DataBind();
}

XmlDocument from google analytics to flat file c#

Using C# I have extracted data from Google Analytics Data API and have got it in an xmldocument. From that point I want to export it to flat file format (txt file). I am trying to use the xmlnode class to write out element attribute values within the 'entry' elements but cant do it. XML code below:

....so on.....
In the code below I need to change it to locate the entry elements, but can't find it. Using "/entry" yields nothing.
XmlNamespaceManager xmlnsm = new XmlNamespaceManager(xmld.NameTable);
xmlnsm.AddNamespace("dxp", "http://schemas.google.com/analytics/2009");
xmlnsm.AddNamespace("openSearch", "http://a9.com/-/spec/opensearch/1.1/");
xmlnsm.AddNamespace("gd", "http://schemas.google.com/g/2005");
foreach (XmlNode xmlnd in xmld.SelectNodes("//dxp:dimension", xmlnsm))
{
DimVal = xmlnd.Attributes["value"].Value.ToString();
DimName = xmlnd.Attributes["name"].Value.Replace("ga:", "");
// ...
}
I could be missing a namespace. Can anyone please help me out?
XDocument xDoc = XDocument.Load(fileToLoad); //or XDocument.Parse(xmlString)
XNamespace dxp = "http://schemas.google.com/analytics/2009";
XNamespace ns = "http://www.w3.org/2005/Atom";
var result =
xDoc.Descendants(ns + "entry")
.Select(e => new
{
Dimension = e.Descendants(dxp + "dimension")
.ToDictionary(d => d.Attribute("name").Value, d => d.Attribute("value").Value),
Metric = e.Descendants(dxp + "metric")
.ToDictionary(d => d.Attribute("name").Value, d => d.Attribute("value").Value)
})
.ToList();
Print the result:
foreach(var entry in result)
{
foreach (var dim in entry.Dimension)
Console.WriteLine(dim.Key + " = " + dim.Value);
Console.WriteLine();
foreach (var met in entry.Metric)
Console.WriteLine(met.Key + " = " + met.Value);
Console.WriteLine("---------------");
}
If you're just interested in getting all of the dxp:dimension elements you could use
GetElementsByTagName("dimension", "http://schemas.google.com/analytics/2009")
instead of
SelectNodes("//dxp:dimension", xmlnsm)
If you're intent on using SelectNodes, I think you need another / ("///dxp:dimension").
Specifically for your case you can do:
foreach(XmlElement ele in xmld.GetElementsByTagName("element"))
{
foreach(XmlElement dim in ele.GetElementsByTagName("dimension", "http://schemas.google.com/analytics/2009")
{
// Do w/e w/ the element
}
foreach(XmlElement met in ele.GetElementsByTagName("metric", "http://schemas.google.com/analytics/2009")
{
// Do w/e w/ the element
}
}

<append name="G" ITEM="10" />
</ToAppend>
How can I loop through all of the attributes in //ToAppend/append and if 'name' is a match in //funds/fund add the attribute ITEM from //ToAppend/append to //funds/fund ?
I'm trying to append the matching items to the first list but I'm not having too much luck. Trying to get this working via C# under the 2.0 framework.
Thanks in advance!
edit:
XmlNode xmlNodeInner = root.SelectSingleNode("//ToAppend/append");
XmlNode ToBeUpdated = root.SelectSingleNode("//funds/fund");
foreach (XmlElement element in ToBeUpdated)
{
Console.WriteLine(element.InnerXml);
//Match the 'name' from xmlNodeInner to the 'name' of ToBeUpdated
//if{magic occurs here and they match}
{
element.SetAttribute("ITEM6", "value from xmlNodeInner");
}
}
I just dont know how to do the comparison inquiry to determine if A=A, or even exists, since there is no guarentee on that.
Hopefully it would come out something like:
<fund name="G" ITEM0="3%" ITEM1="3%" ITEM2="3%" ITEM3="5%" ITEM4="5%" ITEM5="" ITEM6="10"/>
This seems to work:
namespace ConsoleApplication1
{
using System;
using System.Xml;
class Program
{
static void Main( string[] args )
{
const string xml = #"
<root>
<funds>
<fund name='A' ITEM0='7%' ITEM1='8%' ITEM2='9%' ITEM3='10%' ITEM4='11%' ITEM5='' />
<fund name='B' ITEM0='11%' ITEM1='11%' ITEM2='13%' ITEM3='14%' ITEM4='16%' ITEM5='' />
<fund name='C' ITEM0='' ITEM1='' ITEM2='' ITEM3='' ITEM4='' ITEM5='' />
<fund name='D' ITEM0='7%' ITEM1='8%' ITEM2='9%' ITEM3='10%' ITEM4='11%' ITEM5='' />
<fund name='E' ITEM0='2%' ITEM1='3%' ITEM2='3%' ITEM3='5%' ITEM4='5%' ITEM5='' />
<fund name='F' ITEM0='' ITEM1='' ITEM2='' ITEM3='' ITEM4='' ITEM5='' />
<fund name='G' ITEM0='3%' ITEM1='3%' ITEM2='3%' ITEM3='5%' ITEM4='5%' ITEM5='' />
</funds>
<ToAppend>
<append name='A' ITEM='10' />
<append name='B' ITEM='15' />
<append name='C' ITEM='20' />
<append name='D' ITEM='20' />
<append name='E' ITEM='15' />
<append name='F' ITEM='10' />
<append name='G' ITEM='10' />
</ToAppend>
</root>
