Renaming XSLT attribute value from C# code

Renaming XSLT attribute value from C# code - c#

I have XSLT as below :-
<ServiceRequest ExternalSystemName="ServiceNow" Company="{ServiceRequest-Company}">
<xsl:if test="{ServiceRequest-LastResolvedDate} and {ServiceRequest-LastResolvedDate} != ''" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:attribute name="LastResolvedDate">
<xsl:value-of select="{ServiceRequest-LastResolvedDate}" />
</xsl:attribute>
</xsl:if>
<xsl:if test="{ServiceRequest-ServiceType} and {ServiceRequest-ServiceType} != ''" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:attribute name="ServiceType">
<xsl:value-of select="'SR'" />
</xsl:attribute>
</xsl:if>
...
...
I want to rename particular attribute name via C# code.
For that I had written below code :-
var property = root.Descendants(elementName).Descendants().Attributes("name").Where(x => x.Value == "LastResolvedDate");
foreach (var item in property)
{
item.Name = "renamed_new_name";
}
This code gives me error that atribute name cannot be assigned and is readonly.
What can be the possible solution?
EDIT 1 :
It is changing attribute name :-
<xsl:if test="LastResolvedOn/value and LastResolvedOn/value != ''">
<xsl:attribute renamed_new_name="LastResolvedOn">
<xsl:value-of select="LastResolvedOn/value" />
</xsl:attribute>
</xsl:if>
Where I needed :-
<xsl:if test="LastResolvedOn/value and LastResolvedOn/value != ''">
<xsl:attribute name="renamed_new_name">
<xsl:value-of select="LastResolvedOn/value" />
</xsl:attribute>
</xsl:if>

You need to remove the existing attribute and add a new one, e.g.:
var elements = root.Descendants(elementName).Descendants()
.Where(x => (string)x.Attribute("name") == "LastResolvedDate");
foreach (var item in elements)
{
item.Attribute("name").Remove();
item.Add(new XAttribute("renamed_new_name", "LastResolvedDate"));
}

C# SQL Update Query with multiple symbols

I'm creating a piece of software that should let me update a value in an SQLite DB.
The problem is, this value contains a lot symbols (originally an xml AS value).
I've tried refractor this but I'm just not able to. Is there a faster way to do so maybe?
Thank you in advance!

XSLT in a loop keep getting only first file transformation in the output. How to Stop caching XSLT output

When I am looping thru list of files and doing transformation on each file in a folder the effect of the transformation is as if it keeps transforming first file again and again. The transformation looked to be caching.
Here is the Code for transformation:
I am doing this inside WebAPI call.. in .NET framework 4.5.2 version . The ASP.NET page is calling the WebAPI.
I tried all different overloads and moving instancing transformation new out of loop on the top. I did not find any easy way of disabling the caching.
var d = new DirectoryInfo(strXMLFolder);
foreach (FileInfo file in d.GetFiles())
{
String strXSLTFile = strParamArr[2];
String xmlFile = file.Name;
//File.WriteAllBytes(strFile, transferObj.XSLTTemplateFileData);
XslCompiledTransform proc = new XslCompiledTransform();
proc.Load(strXSLTFolder + strXSLTFile);
proc.Transform(strXMLFolder + xmlFile, strXMLFolder + xmlFile + "-IntermediateXML.xml");
..................................
The XSLT file has following Code:

I expect different output in each intermediate.XML file but I keep getting the fist file result in the output in intermediate file.

c# XDocument : Check if particular node name exists , if not add

I have below node which needs to be added in xslt if not exists :-
<xsl:template name="URLSpliter">
<xsl:param name="url" />
<xsl:variable name="splitURL" select="substring-after($url, '/')" />
<xsl:if test="contains($splitURL, '/')">
<!--To call the template recursively-->
<xsl:call-template name="URLSpliter">
<xsl:with-param name="url" select="$splitURL" />
</xsl:call-template>
</xsl:if>
<xsl:if test="not(contains($splitURL, '/'))">
<xsl:value-of select="$splitURL" />
</xsl:if>
</xsl:template>
For this, first I need to check if it exists or not ?-
I have checked it through -
IEnumerable<XElement> xElements = from xmlAuthor in doc.Descendants()
let xElement = xmlAuthor.Element("URLSpliter")
where xElement != null
select xmlAuthor;
var IsUrlSplitterExists= xElements.Any();
if(IsUrlSplitterExists)
{
}
1.I want to know if its correct way or not?
If not exists (element [name="URLSpliter"]) then needs to add.
How can I add it as a first node of xslt?

To select such elements in the XSLT namespace with LINQ to XML you would use
XNamespace xsl = "http://www.w3.org/1999/XSL/Transform";
if (!doc.Root.Elements(xsl + "template").Where(t => (string)t.Attribute("name") == "URLSplitter").Any()) {
doc.Root.AddFirst(new XElement(xsl + "template", new XAttribute("name", "URLSplitter"), ...))
}
Of course, as XSLT is XML, you might as well use XSLT to manipulate your XSLT:
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:axsl="http://www.w3.org/1999/XSL/Transform-alias"
exclude-result-prefixes="axsl"
version="1.0">
<xsl:namespace-alias stylesheet-prefix="axsl" result-prefix="xsl"/>
<xsl:output indent="yes"/>
<xsl:param name="new-template">
<axsl:template name="URLSpliter">
<axsl:param name="url" />
<axsl:variable name="splitURL" select="substring-after($url, '/')" />
<axsl:if test="contains($splitURL, '/')">
<!--To call the template recursively-->
<axsl:call-template name="URLSpliter">
<axsl:with-param name="url" select="$splitURL" />
</axsl:call-template>
</axsl:if>
<axsl:if test="not(contains($splitURL, '/'))">
<axsl:value-of select="$splitURL" />
</axsl:if>
</axsl:template>
</xsl:param>
<xsl:template match="#* | node()">
<xsl:copy>
<xsl:apply-templates select="#* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="xsl:transform[not(xsl:template[#name = 'URLSplitter'])] | xsl:stylesheet[not(xsl:template[#name = 'URLSplitter'])]">
<xsl:copy>
<xsl:apply-templates select="#*"/>
<xsl:copy-of select="$new-template"/>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>

Problem is:
Now display the detail in some different format for alternate row. currently, every offer has image in left side and description in right, for alternate row now i want to display description in left and image in right, i have never used xslt file before, can anyone please help... or suggest me how can achieve this.
waiting for your helpful answers..

i have solved out this problem..
Here is the solution, we didn't need to changes anything in c# code(code behind), we have just changed the xslt file t do this, as xslt file number of inbuilt functions to do.
I have used mod as below:
<xsl:for-each select=". | following-sibling::Offer[(position()) < $OffersPerPage]" >
<xsl:choose>
<xsl:when test="position() mod 2 = 1">
data 1
</xsl:when>
<xsl:otherwise>
data 2
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
That's all.....

C# FlowDocument to HTML conversion

Basically, I have a RichTextBox and I want to convert the formatted contents of it to HTML so it can be sent as an email.
The method I am currently using does not give any formatting at all:
string message = new TextRange(messageTextBox.Document.ContentStart,
messageTextBox.Document.ContentEnd).Text;
So I searched around and found this, however, it is over 5 years old and in the comments an MSFT user has commented saying that it is no longer supported - "This sample has been removed from our sample set and is no longer supported", and the HTML it generates is in an older format than modern HTML or XHTML which would be better to have.
Can anybody show me how I can convert the formatted contents of a RichTextBox to HTML?
(So when the email is sent it the recipient sees the email with formatting)

The general technique is to use a XamlWriter to convert the FlowDocument content to a stream of XML, and then to use an XSLT transform to convert the XML to HTML. That's not much of an answer, but that's because there's a huge range of possible HTML representations of any given FlowDocument.
This transform, for instance, converts every top-level Section to a div, every Paragraph to a p, and every Run to a span whose class tells you whether or not it's italicized, bold-faced, or underlined, or any combination of the above. It was useful for the purpose I wrote it for, but to call it a lossy transformation is an understatement:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

exclude-result-prefixes="msxsl x">
<xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>
<xsl:template match="x:Section[not(parent::x:Section)]">
<div>
<xsl:apply-templates select="node()"/>
</div>
</xsl:template>
<xsl:template match="x:Section">
<xsl:apply-templates select="node()"/>
</xsl:template>
<xsl:template match="x:Paragraph">
<p>
<xsl:apply-templates select="node()"/>
</p>
</xsl:template>
<xsl:template match="x:Run">
<xsl:variable name="class">
<xsl:if test="#FontStyle='Italic'">
<xsl:text>i </xsl:text>
</xsl:if>
<xsl:if test="#FontWeight='Bold'">
<xsl:text>b </xsl:text>
</xsl:if>
<xsl:if test="contains(#TextDecorations, 'Underline')">
<xsl:text>u </xsl:text>
</xsl:if>
</xsl:variable>
<span>
<xsl:if test="normalize-space($class) != ''">
<xsl:attribute name="class">
<xsl:value-of select="normalize-space($class)"/>
</xsl:attribute>
</xsl:if>
<xsl:value-of select="text()"/>
</span>
</xsl:template>
</xsl:stylesheet>
Here's a value converter I wrote to do the conversion - note that in order to use the value converter, you also have to hack around and implement a version of RichTextBox that exposes the content as a dependency property. Really this whole project was a pain.
public class FlowDocumentToHtmlConverter : IValueConverter
{
private static XslCompiledTransform ToHtmlTransform;
private static XslCompiledTransform ToXamlTransform;
public FlowDocumentToHtmlConverter()
{
if (ToHtmlTransform == null)
{
ToHtmlTransform = LoadTransformResource("Converters/FlowDocumentToXhtml.xslt");
}
if (ToXamlTransform == null)
{
ToXamlTransform = LoadTransformResource("Converters/XhtmlToFlowDocument.xslt");
}
}
private static XslCompiledTransform LoadTransformResource(string path)
{
Uri uri = new Uri(path, UriKind.Relative);
XmlReader xr = XmlReader.Create(Application.GetResourceStream(uri).Stream);
XslCompiledTransform xslt = new XslCompiledTransform();
xslt.Load(xr);
return xslt;
}

}
if (targetType != typeof(string))

throw new InvalidOperationException(

}
FlowDocument d = (FlowDocument)value;

using (StringWriter sw = new StringWriter(sb))
{
XmlWriterSettings xws = new XmlWriterSettings();
xws.OmitXmlDeclaration = true;
XmlReader xr = XmlReader.Create(ms);
XmlWriter xw = XmlWriter.Create(sw, xws);
ToHtmlTransform.Transform(xr, xw);
}
return sb.ToString();
}

For those who is looking for solution for .Net Core (APS.Net Core) - nuget MarkupConverter did the trick for me. Add dependency reference
<PackageReference Include="MarkupConverter" Version="1.0.6" />
Then use it
MarkupConverter.MarkupConverter markupConverter = new MarkupConverter.MarkupConverter();
try
{
message = markupConverter.ConvertXamlToHtml(message);
}
catch (Exception ex)
{
_logger.LogError(ex, $"Failed to parse flowdocument");
