Manipulate SSIS Package Using XmlDocument

I'm downgrading a SSIS package from 2014 to 2012. This processneeds to some search/replace and I know to do that manually.
Now I'm trying to write a C# program to do the job.
This is the XML in .DTSX file.
<?xml version="1.0"?>
<DTS:Executable xmlns:DTS="www.microsoft.com/SqlServer/Dts"
DTS:refId="Package"
DTS:CreationDate="8/10/2016 11:39:29 AM"
DTS:CreationName="Microsoft.Package"
DTS:CreatorComputerName="FD89D67CEC21F"
DTS:CreatorName="CORP\ZKHEKRZ"
DTS:DTSID="{63B7F2FE-2D47-4710-82DF-83C92B7010B5}"
DTS:ExecutableType="Microsoft.Package"
DTS:LastModifiedProductVersion="12.0.4100.1"
DTS:LocaleID="1033"
DTS:ObjectName="CubeDailyBackup"
DTS:PackageType="5"
DTS:VersionBuild="131"
DTS:VersionGUID="{8F0EAFC9-D73C-463C-8D5E-CB33C858D0D5}">
<DTS:Property DTS:Name="PackageFormatVersion">8</DTS:Property>
....... more lines below
At first step I need to replace
<DTS:Property DTS:Name="PackageFormatVersion">8</DTS:Property>
with
<DTS:Property DTS:Name="PackageFormatVersion">6</DTS:Property>
To do the job, I load .DTSX file using XmlDocument and then find the node using below code
private XmlDocument Pkg14 = new XmlDocument();
Pkg14.Load("mypackage.dtsx");
XmlNodeList xnList = Pkg14.SelectNodes("//DTS:Property[#DTS:Name='PackageFormatVersion']");
Executing the third line throws below error:
Namespace Manager or XsltContext needed. This query has a prefix,
variable, or user-defined function
Please advise.
EDIT:
I tried adding below code before Pkg14.SelectNodex but it did not help:
XmlNamespaceManager xmlnsManager = new XmlNamespaceManager(Pkg14.NameTable);
xmlnsManager.AddNamespace("xs", "http://www.w3.org/2001/XMLSchema");
xmlnsManager.AddNamespace("DTS", "www.microsoft.com/sqlserver/dts/tasks/webservicetask");
..... and adding more namespace

Make sure you have the correct URL mapped to the prefix (DTS prefix in your code mapped to a different URI from the one in your XML). Also make sure you pass the XmlNamespaceManager along with the XPath query to SelectNodes() or SelectSingleNode() method :
Pkg14.Load("mypackage.dtsx");
XmlNamespaceManager xmlnsManager = new XmlNamespaceManager(Pkg14.NameTable);
xmlnsManager.AddNamespace("xs", "http://www.w3.org/2001/XMLSchema");
xmlnsManager.AddNamespace("DTS", "www.microsoft.com/SqlServer/Dts");
XmlNode node = Pkg14.SelectSingleNode("//DTS:Property[#DTS:Name='PackageFormatVersion']", xmlnsManager);
node.InnerText = "6";
//save the modified XmlDocument back to file
Pkg14.Save("mypackage.dtsx");

Remove an XML node by its content

I Have a XML file that I want remove a node that it's content is 'test'.
I search entire Google, so doesn't help me or I can't get my answer.
The XML file content is shown below:
<?xml version="1.0" encoding="utf-8"?>
<parent>
<child>C#</child>
<child>VB</child>
<child>VB.net</child>
<child>F#</child>
<child>C++</child>
<child>C</child>
<child>Ruby</child>
<child>Pascal</child>
<child>test</child>
<child>python</child>
</parent>
I can load it to any list. So my address is OK.
But can't remove the node that its content is test.
One of my tried code is:
XmlDocument doc = new XmlDocument();
doc.Load(Address);
XmlNode node = doc.SelectSingleNode("/parent/child[text()='test']");
doc.ParentNode.RemoveChild(node);
doc.Save(Address);
any suggestion will be appreciable.
Update: Thanks to Andrei Vatasescu the correct answer is:
node.ParentNode.RemoveChild(node);
instead of :
doc.ParentNode.RemoveChild(node);

Actually the program as posted originally works fine, there is just one small error: "ParentNode.RemoveChild()" should be called on node instead of doc.

Try this:
foreach (XmlNode node in doc.ChildNodes)
{
if (node.InnerText == "test")
{
doc.RemoveChild(node);
}
}

Load an XML and add a node to it

What I am trying to do is when I press a button, I load an XML file and try to add nodes to it.
XmlDocument doc = new XmlDocument();
doc.Load("XMLFILE.xml");
XmlNode Tag1 = doc.CreateElement("Tag1");
XmlNode Tag2 = doc.CreateElement("Tag2");
Tag2.InnerText = food.Text;
Tag1.AppendChild(Tag2);
XmlNode Tag3 = doc.CreateElement("Tag3");
Tag3.InnerText = games.Text;
Tag1.AppendChild(Tag3);
XmlNode Tag4 = doc.CreateElement("Tag4");
Tag4.InnerText = life.Text;
Tag1.AppendChild(Tag4);
When I run the code and click the button the file is empty and only has 1 tag which is one I made when I first created the file. So how can I load an XML and add to it?

There are two issues with the code you posted:
You created a bunch of XML nodes but I don't see anywhere that you actually add them to the document you loaded. You need to call AppendChild() on the DocumentElement or some other node that's already in the file if you want your new nodes to appear in the XML tree.
Your code is loading an XML document from disk into memory and editing it, but you are never storing the XML document back to disk again. You need to call Save() on the updated document if you want to see the changes persisted back to your file.

How to change the data within elements in a XML file using C#?

I'm kind of new to XML files in C# ASP.NET. I have a XML in the below format:
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<Installation>
<ServerIP>192.168.20.110</ServerIP>
<DB_Name>USTCKT1</DB_Name>
<Username>jorame</Username>
<Password>Cru$%e20</Password>
<Table_PreFix>TCK</Table_PreFix>
</Installation>
I need to change the values within each element. For example, when an user clicks I should be able to replace 192.168.20.110 with 192.168.1.12.
How can I accomplish this? Any help will be really appreciated.

You should look at using the methods in the XDocument class. http://msdn.microsoft.com/en-us/library/bb301598.aspx
Specifically look at the methods: Load(string) - to load an XML file, Element() - to access a specific element and Save(string) - to save the XML document. The page on Element() has some sample code which can help.
http://msdn.microsoft.com/en-us/library/system.xml.linq.xcontainer.element.aspx

You can do something like this using the XDocument class:
XDocument doc = XDocument.Load(file.xml);
doc.Element("Installation").Element("ServerIP").Value = "192.168.1.12";
//Update the rest of the elements
doc.Save(file.xml);
More Details
If you run into namespace issues when selecting your elements you will need to include the xml namespace in the XElement selectors eg doc.Element(namspace + "Installation")

In general, you can do it in the following steps:
Create a new XmlDocument object and load the content. The content might be a file or string.
Find the element that you want to modify. If the structure of your xml file is too complex, you can use xpath you find what you want.
Apply your modification to that element.
Update your xml file.
Here is a simple demo:
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load("file.xml"); // use LoadXml(string xml) to load xml string
string path = "/Installation/ServerIP";
XmlNode node = xmlDoc.SelectSingleNode(path); // use xpath to find a node
node.InnerText = "192.168.1.12"; // update node, replace the inner text
xmlDoc.Save("file.xml"); // save updated content
Hope it's helpful.

Replacing the innertext of an Xml node/element

First of all this is C#. I am creating a internet dashboard for a small group of colleages in the NHS.
Below is an example xml file in which I need to change the innertext of. I need to replace a specific element for example "Workshop1." Because we have a few workshops I cannot afford to use a general writer because it will replace all the information on the XML document with this one bit of code below.
<?xml version="1.0" ?>
<buttons>
<workshop1>hello</workshop1>
<url1>www.google.co.uk</url1>
I am using a switch case to select a specific workshop where you can change the name and add a URL of the workshop and using this code below will replace the whole document.
public void XMLW()
{
XmlTextReader reader = new XmlTextReader("C:\\myXmFile.xml");
XmlDocument doc = new XmlDocument();
switch (comboBox1.Text)
{
case "button1":
doc.Load(reader); //Assuming reader is your XmlReader
doc.SelectSingleNode("buttons/workshop1").InnerText = textBox1.Text;
reader.Close();
doc.Save(#"C:\myXmFile.xml");
break;
}
}
So just to clarify I want my C# program to search through the XML document find the element "Workshop1" and replace the innertext with text from a textBox. and be able to save it without replacing the whole document with one node. Thanks for looking.

Using XmlDocument and XPath you can do this
XmlDocument doc = new XmlDocument();
doc.Load(reader); //Assuming reader is your XmlReader
doc.SelectSingleNode("buttons/workshop1").InnerText = "new text";
You can use doc.Save to save the file also.
Read more about XmlDocument on MSDN.
EDIT
To save the document do this
doc.Save(#"C:\myXmFile.xml"); //This will save the changes to the file.
Hope this helps you.
