I have an XML in the following format:

XML

<?xml-stylesheet href="...css" type="text/css"?>
<repub>
    <head>
        <title>Main Title</title>
    </head>
    <body>
    <sec name="sec_1">
        <title>Section Title</title>
        <break name="article_6-3">
            <h1>
                <page num="6" />
                <bl>Article Title</bl>
            </h1>
            <fig><img src="images/img_6-3.jpg" alt=""/></fig>
            <p>
                <bl>
                <il>Paragraph italic value</il> and bold value.</bl>
            </p>
            <pw>Paragraph value</pw>
        <fig><img src="images/img_6-4.jpg" alt=""/></fig>
</break>
</sec>
</body>
</repub>

I want the XML child nodes to be in the same line as the parent, like:

XML

<?xml-stylesheet href="...css" type="text/css"?>
<repub>
    <head>
        <title>Main Title</title>
    </head>
    <body>
    <sec name="sec_1">
        <title>Section Title</title>
        <break name="article_6-3">
            <h1><page num="6" /><bl>Article Title</bl></h1> //Change 1
            <fig><img src="images/img_6-3.jpg" alt=""/></fig>
            <p><bl><il>Paragraph italic value</il> and bold value.</bl></p> //Change 2
            <pw>Paragraph value</pw>
        <fig><img src="images/img_6-4.jpg" alt=""/></fig>
</break>
</sec>
</body>
</repub>

Upon creating the XML, every time the indent also comes up and I can try to somehow manage to remove the indentation, but I am totally clueless as to how can I keep the child nodes in the same line as the parent.

I don't know what to do. Please help.

What I have tried:

C#

XDocument xdoc = new XDocument();
                string filecontent = PreProcessXMLnondpvrepub(xmlfile);
                byte[] myByteArray = System.Text.Encoding.UTF8.GetBytes(filecontent);
                MemoryStream ms = new MemoryStream(myByteArray);
                StreamReader sr = new StreamReader(ms);
                xdoc = XDocument.Load(sr, LoadOptions.PreserveWhitespace);
                sr.Dispose();
                ms.Dispose();
                myByteArray = null;

private string PreProcessXML(String xmlpath)
        {
            StringBuilder sb = new StringBuilder();

            string openbreak = "";
            string closebreak = "";
            string secreplace = "";
            string boldreplace = "";
            int seccount = 1;

            foreach (var line in File.ReadLines(xmlpath))
            {

Is there any reason you want to change normal XML nodes behaviour?
BTW: Show the method you use to save xml file...

Primo Chalice 19-Mar-19 5:11am

Yes, actually I am working on a project and there are some required changes to be made before the final output. Multiple output types have multiple variants.

For example, <bl> becomes < span class="ld_bold"> and < pw> becomes < p>.

So, if it is in one line, I can use StringBuilder and replace the values.

Show the method you use to save xml file...
You need to add more details aout final xml conversion.

Since the code is long, I am providing a link with the content.

Sorry, but no one won't download a source code from unknown source. And no one want to study someones project. You need to shortly explain what you want to achieve and why it's not working for you. You should post related code too. Use "Improve question" widget.

You're doing it wrong way. That's what you want to achieve is called XSLT Transformations | Microsoft Docs[^]. Here you'll find very interesting article: Transform From One XML Structure to Another[^]

Seems, that basically, you want to add <span someproperty="somevalue">...</span> inside each node, depending on its name. So, a hard-coded version may loop through the collection of XElement[^] or XNode[^] and change its content based on your logic. See:

foreach(XElement xele in xdoc.Root.Descendants("pw"))
{
	string tmpVal = xele.Value;
	xele.Name = "p"; //change pw => p
	xele.Value = "";
	xele.Add(new XElement("span", tmpVal));  //add a "span" node! 
	Console.WriteLine("{0}", xele.ToString());
}

result:

<p>
  <span>Paragraph value</span>
</p>

Good luck!
