I have an XML file with structure:
<?xml version='1.0'?>
<a>
<b>
<d>
<LineCode>0</LineCode>
<LineName>Metro</LineName>
<LineDescription>Test C&C all countries with MCFM</LineDescription>
</d>
.......
<e>.....</e>
<f>....</f>
</b>
</a>
In this file I have added section with following code:
XElement newElement = new XElement("e",
new XElement("e1", "test1"),
new XElement("e2", "test2"),
new XElement("e3", "test3 ));
doc.Root.Element("a").Element("d").AddAfterSelf(newElement);
doc.Save(file.Directory + "//" + file.Name);
After i run this code all my special chars used in the initial XML file are modified .
For exemple first row became:
<?xml version="1.0" encoding="utf-8"?>
line became:
<LineDescription>Test C&C all countries with MCFM</LineDescription>
How to add the new section in my XML file without modifying the existing chars?Or how to save without modifying existing special chars?
== Observation #1 ==
<!-- Before: -->
<?xml version='1.0'?>
<!-- After: -->
<?xml version="1.0" encoding="utf-8"?>
Explanation: If the encoding attribute is omitted, utf-8 is the default.
== Observation #2 ==
<!-- Before: -->
&
<!-- After: -->
&
Explanation: These XML entities for representing the ampersand are equivalent.
== Summary ==
The new files are to be used by other applications and it is possible that there
might be problems reading or processing the new files.
Well-behaved XML processing software should treat your before- and after- documents in an equivalent fashion. So, if you encounter problems reading or processing the newly edited XML files, those problems really should be addressed. But it is possible that you may not have the kinds of problems that you anticipate.
If the code processing your file is supposed to handle standard XML, it should not matter which form the characters are stored in. Your original file is using the numeric code for the character, while the newly saved file is using the standard entity name. The same applies for the XML header line - version='1.0' and version="1.0" - should be treated exactly the same, and the additional element just identifies which character set was used in writing the file.
Provided your other applications are using standard XML parsers, or custom parsers which are capable of reading standard XML there should be no problem with the modified XML. The only issue you might have is if these other applications cannot read standard XML (ie they assume that all values use single quotes, or they don't correctly process the XML standard entities, etc) - in this case you may need to use a filtering parser on any file sent to those applications to ensure that these requirements are met. (ie a simple SAX parser which writes out the file as the events are triggered using the additional limitations)

I am new to C# web development. I am developing a software that receives response from webservice in XML format. (includes barcodes generated by webservice).
There is an option given by webservice provider, that i have to add a line
(Example<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">)
as a second line in the xml and display in web browser by using style sheets provided by webservice provider. If i have to choose this option, how can i add that line as second line in the received xml file also how can i map the style sheets provided by the webserive in the project for this xml.
If i dont take that option, Is it possible to display the data in xml as a pdf(includes barcodes generated by webservice), if i dont choose the option .
If I understand your question correctly, you want to:
Add a stylesheet specification to an existing XML
Convert an XML to PDF
1. ADDING A STYLESHEET
There is an option given by webservice provider, that i have to add a line [...] as a second line in the xml and display in web browser by using style sheets
This is done using e.g. Linq, like in this answer.
First of all, I think the example you used, i.e.
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
may be inaccurate, as it is the first line of a XSL file (a stylesheet); those kind of files are used to transform an XML into another file (a different XML or an HTML, like in your case). However, you say
using style sheets provided by webservice provider
so my guess is that you already have those stylesheets and you can you use them, rather than creating them yourself.
If so, the line you want to add is like
<?xml-stylesheet type="text/xsl" href="helloWorld.xsl"?>
Let's suppose you already have your XML stored into an XDocument variable named "Document" with its root element being "Root"
var FilePath = "Example.xml";
var Document = XDocument.Load(FilePath);
var Root = XDocument.Descendants("Root").Single();
Then you can add your stylesheet this way, getting a new XML:
var NewDocument = new XDocument(
new XProcessingInstruction("xml-stylesheet", "type='text/xsl'ref='helloWorld.xsl'"),
Root);
2. XML to PDF
There are several ways to do this.
You might parse your XML, retrieve the elements you want to show on your PDF, use a library like iTextSharp to create a specific layout and place their contents on the file.
Or, since you already have an XML and you can transform it to an HTML using an XSL, you can use wkHtmlToPdf.
Let me know if you need more details.
I am writing a console application that generates an XML file that will be consumed by a server job processing application that was written a long time ago. The server app requires a processing instruction: <?JtJob jobname?>. I'm using C# XDocument to generate my xml:
XDocument xml = new XDocument(new XProcessingInstruction("JtJob", "FieldInspection3_Rejected"),
new XElement("Document",
new XElement("DataFile", tempFileName),
new XElement("FormType","Corrected Form Package"),
new XElement("BYOD_RejectComment",reasonForRejection),
new XElement("BYOD_FromTech",techEmail)
)
);
xml.Save(Path.Combine("C:\\Data", DateTime.Now.ToString("yyyyMMdd_HHmmssffff") + "_Rejected.xml"));
For some reason, the server app requires the processing instruction to be on the first line. If my xml file looks like this:
<?xml version="1.0" encoding="utf-8"?><?JtJob FieldInspection3_Rejected?>
<Document>
<DataFile>C:\Windows\TEMP\tmp387F.tmp</DataFile>
<FormType>Corrected Form Package</FormType>
<BYOD_RejectComment>you're ugly</BYOD_RejectComment>
<BYOD_FromTech>example#gmail.com</BYOD_FromTech>
</Document>
Everything works fine. But when it looks like this:
<?xml version="1.0" encoding="utf-8"?>
<?JtJob FieldInspection3_Rejected?>
<Document>
<DataFile>C:\Windows\TEMP\tmp387F.tmp</DataFile>
<FormType>Corrected Form Package</FormType>
<BYOD_RejectComment>you're ugly</BYOD_RejectComment>
<BYOD_FromTech>example#gmail.com</BYOD_FromTech>
</Document>
It errors. My problem is, using the XDocument code above, it generates the second output.
Without loading my generated xml back in as a string and manipulating the string, is there a way for me to tell XDocument to create the processing instruction on the first line?
I know the blame is definitely to be placed on the server app for not accepting valid XML syntax, but my goal is to get this to work, not fix a 20 year old program.
Edit: Thanks! Using the save override preserved the formatting. Didn't make it all one line, but it allowed me to keep the PI on line 1.
Edit 2: Well, that didn't help me either. But I found out what would help me! XDocument.Save() by default outputs UTF8 With BOM. I changed it to without BOM by using XMLTextWriter and that worked.
What if you used the XDocument.Save(String, SaveOptions) method to get an output all on a single line?
So do this instead:
xml.Save(fileName, SaveOptions.DisableFormatting);
This would force the declaration to be onto the first line with the downside of having the entire document on the first line, but if it works for that program then so be it.
You'll want to use a XDocument.Save() overload that allows you to specify formatting options:
xml.Save(Path.Combine("C:\\Data", DateTime.Now.ToString("yyyyMMdd_HHmmssffff") + "_Rejected.xml"),
SaveOptions.DisableFormatting);
https://msdn.microsoft.com/en-us/library/bb551426(v=vs.110).aspx
Before I get into the issue, I'm aware there is another question that sounds exactly the same as mine. However, I've tried that solution (using Notepad++ to encode the xml file as UTF-8 (without BOM) ) and it doesn't work.
XmlDocument namesDoc = new XmlDocument();
XmlDocument factionsDoc = new XmlDocument();
namesDoc.LoadXml(Application.persistentDataPath + "/names.xml");
factionsDoc.LoadXml(Application.persistentDataPath + "/factions.xml");
Above is the code I have problems with. I'm not sure what the problem is.
<?xml version="1.0" encoding="UTF-8"?>
<factions>
<major id="0">
...
Above is a section of the XML file (the start of it - names.xml is also the same except it has no 'id' attribute). The file(s) are both encoded in UTF-8 - in the latest notepad++ version, there is no option of "encode in UTF-8 without BOM" afaik UTF-8 is the same as UTF-8 without BOM.
Does anyone have any idea what the cause may be? Or am I doing something wrong/forgetting something? :/
You are receiving an error because the .LoadXml() method expects a string argument that contains the XML data, not the location of an XML file. If you want to load an XML file then you need to use the .Load() method, not the .LoadXml() method.
I am working on a C# and Android library project. What I am basically trying to do is write a library in Android that will send me crash details onto my server.
I then have a C# console application that runs on my server and processes the data received by Android and from this data I want to generate an XML file, so that another program can read in the XML file and provide a monthly report.
I've got stuck with the best way of writing and reading the XML though.
I've read a lot about it and found various things such as XMLWriter or XMLSerializer but I don't know which works best, nor do I understand entirely how these are implemented.
Below is a basic design of how the XML file should be written, this is what I've written manually to give an understanding of what I want to achieve.

Thanks for any help you can provide.
Our team typically uses LINQ to XML, which provides a really powerful way to work with XML data (including loading XML from files, parsing XML streams, creating XML document and writing/saving XML to files.)
The following link provides a good overview of LINQ to XML
http://www.dreamincode.net/forums/topic/218979-linq-to-xml/
In addition, you may find “the XML part” section of the following page helpful

Personally, I prefer to use LINQ to XML for any XML related stuff in C#. You can create XML Trees, and then persist/serialize those trees to file, XmlWriter, or other types of streams.
But in cases when I need huge performance, I prefer to create XML using StringBuilder class and string concatenation operations.
I am trying to send xml to a java-based web service given to me by a third party via a c#.NET application, and I get the org.xml.sax.SAXParseException: Content is not allowed in prolog error.
I have verified the xml against the schema, and I passed the memorystream I am using to hold the xml to an .xml file, then opened the file with a hex editor to make sure that there were no undesired characters in the prolog, and there are none. When opened, the first characters in the file are
<?xml version="1.0" encoding="utf-8"?>
The class I was given to use to send the xml data to the web service accepts a byte array. I figure that creating the xml using an XmlTextWriter to a utf-8 encoded memorystream, then sending the contents of the stream to a byte array is the most direct method.
I have done a lot of research and tried all the possbilities around this issue that I could find, but nothing works. Could someone please help? Thanks in advance.
By the way, here is a portion of what the web service returns to me. In the payload of the SOAP message, should the data after the element look like that, or be readable xml like the content before it?

I was able to get rid of the problem by removing the UTF encoding. Sounds like in both of our cases, the text wasn't actually UTF-8 encoded.
Do you have a Byte Order Mark at the top of your file that is causing this confusion? Dump or edit the file with a hex dump or hex editor and check the first two or three bytes and ensure that the file starts with

I would guess that something just ahead of this message is out of sync somehow -- the error message appears to indicate that the XML parser thinks it's seeing a comment before it sees the <?xml line.
Just open your XML file with hex editor like hexplorer and then you can be able to see and delete this strange chars, save your file and open with your preferred editor (personally I use Notepad++) and be sure that your file is using UTF-8 encoding :-)
Hope this will help you
I've had no end of problems with C#/Java XML interoperability and Java's handling of the byte order mark (2 or 3 bytes preceeding the XML declaration and identifying the encoding byte order). Java doesn't play nicely with a valid BOM, so you'll have to remove it. Check for it by deriving a byte array and using:
arr[0] == (byte) 0xEF && arr[1] == (byte) 0xBB && arr[2] == (byte) 0xBF
This checks for the 3 byte variant, which is what causes grief :-(
Does the web service operate correctly with other (java) clients?
I've received this error quite a few times, and the source of the error was problems with library dependencies - if I remember correctly, something with JAXB2 in connection with Java5.
