Re: client server communication using DOM Stefan Troschuetz11-Feb-07 1:10 Stefan Troschuetz 11-Feb-07 1:10  The XmlDocument.Load and XmlDocument.Save methods have overloads that take a Stream object, so you should be able to pass in a NetworkStream. Alternatively, you could use the XmlTextReader and XmlTextWriter. Both have a constructor that also takes a Stream object.

Miller 9-Feb-07 7:44  I have an xml document where certain elements have attributes with generic names and values. Like this: Data.xml <DATA sport="football"> <ROW firstname="John" lastname="Doe" s1="130" s2="3" s3="43.3" /> </DATA> And I have metadata which describes the data. The metadata is not in XML format so if there is an alternative to what I'm attempting to do, please let me know. But what I am trying to do is put the metadata in the following format: Meta.xml <METADATA> <FIELDS sport="football"> <FIELD field="s1" name="RushingYards" /> <FIELD field="s2" name="RushingAttempts" /> <FIELD field="s3" name="RushingYardsPerCarry" /> ....... blah, blah, blah ..... </FIELDS> </METADATA> I want to create a stylesheet that can use "Meta.xml" to transform Data.xml into this: <DATA sport="football"> <ROW firstname="John" lastname="Doe" RushingYards="130" RushingAttempts="3" RushingYardsPerCarry="43.3" /> </DATA> The part I don't know how to do is to tell the XslTransform object to transform Data.xml and use Meta.xml as variable input. Can I simply pass Meta.xml in as a parameter to XslTransform? Re: Use one XML document to transform another Mark J. Miller9-Feb-07 13:11 Mark J. Miller 9-Feb-07 13:11  I solved it myself - I ended up using an XmlReader to read Data.xml. Then instead of using Meta.xml I just used the metadata in it's original tabular format. As the process reads Data.xml it looks for ROW elements and checks the names of the attributes against the metadata. While reading Data.xml I create an XmlTextWriter to correspond to the XmlReader. If I need to change the attribute name or value I substitute, otherwise I just output the data from the XmlReader. Remove/Stop the creation of BOM header (C#) Duncan Sample9-Feb-07 2:04 Duncan Sample 9-Feb-07 2:04  I've made a C# application which modifies XML files, but sometimes the resulting file contains the BOM header (EFBBBF hex as first three characters) which the systems which need to take the updated file as input do not accept. I know I could probably open the file after modification and remove the characters, but that seems like a hack. Is there a way to specify the encoding to be something different (or any other way) so that it doesn't create this? The code I'm currently using to open the file is: try<br /> {<br /> xmlDoc = new XmlDocument();<br /> xmlDoc.Load(Filename);<br /> <br /> xpathNav = xmlDoc.CreateNavigator();<br /> return true;<br /> ... Re: Remove/Stop the creation of BOM header (C#) Stefan Troschuetz9-Feb-07 2:44 Stefan Troschuetz 9-Feb-07 2:44  I think it is more interesting to see the code that saves the XML files.

I never came across a property or similar that lets you adjust the usage of a BOM header and after a quick glance at MSDN I also did not find one. In your original post you said that the BOM header is only sometimes put in front of the XML markup. Are you able to narrow this down the some concrete conditions under which this happens?

I have only just come up against this BOM header insertion, but it seems like it could be a certain age (not sure whether it's newer or older at the moment) hardware gives an XML file which ends up being edited in my application and the BOM header added. The file does have the UTF-8 ?xml tag at the top which I am assuming is causing the BOM header to be added by the .NET parser, but that's the bit that causes the hardware unit to not accept the new config file. Re: Remove/Stop the creation of BOM header (C#) Stefan Troschuetz9-Feb-07 5:19 Stefan Troschuetz 9-Feb-07 5:19  Ok, in case you're using Framework 2.0, there may be a way to get around your problem. The XmlDocument.Save method has an overload that takes an XmlWriter object. The XmlWriter class has a overload of the static Create method that takes a filename and a XmlWriterSettings instance (class is new in 2.0). This class exposes a Encoding property that allows to specify the text encoding to be used. Finally there is the UTF8Encoding class that has a constructor taking a boolean that specifies whether the byte order marked is provided or not.

I'm using 2.0, so I'll take a look at writing out in that way. Thanks a lot Re: Remove/Stop the creation of BOM header (C#) Duncan Sample15-Feb-07 2:47 Duncan Sample 15-Feb-07 2:47  That seemed to do the trick, but using this method the XML file is saved without line breaks at all. I've tried changing the various options of XmlWriterSettings but can't work out how to make sure the file is formatted properly. When I was just using xmlDoc.Save it was laying the file out correctly but adding the BOM, now it's saving the file in the right encoding (I chose ASCII rather than UTF-8 as that's what the files I'm editing are in) but without the formatting (which again is causing errors with the hardware units). Re: Remove/Stop the creation of BOM header (C#) Stefan Troschuetz15-Feb-07 3:24 Stefan Troschuetz 15-Feb-07 3:24  I'm sorry to hear it does not work properly. Since I have no pratical experience with customizing the writing of XMl files (output generated by XmlDocument.Save was always sufficient for my needs), I cannot really help you here. The best thing I can suggest is playing around with the properties of the XmlWriterSettings class regarding new lines (obviously you already done this), check whether this only happens if you use the ASCIIEncoding class or also with other encodings and maybe use the same XmlWriterSettings for reading too.

Simply repeating your question does not bring you any closer to getting a useful answer. So I rephrase the question a bit. What should be contained in the XML file and what should the transformation with XSLT do? Did you already read something about XSLT? If not the following site would be a good starting point http://www.w3schools.com/xsl/.
