Ошибка при разборе entityname

I have found that there exists "&" in my code that’s why error is showing

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(dsExport.Tables[0].Rows[i]["SubmissionData"].ToString());

The «&» is there in submissiondata . How can I remove the special characters so that the error doesn’t show again ?

Thanks in advance

Replace your "&" with "&"

I have a function where I am passing a string as params called filterXML which contains ‘&’ in one of the properties.

I know that XML will not recognize it and it will throw me an err. Here is my code:

 public XmlDocument TestXMLDoc(string filterXml)
{
    XmlDocument doc = new XmlDocument();
    XmlNode root = doc.CreateElement("ResponseItems");

    // put that root into our document (which is an empty placeholder now)
    doc.AppendChild(root);

    try
    {
        XmlDocument docFilter = new XmlDocument();
        docFilter.PreserveWhitespace = true;

        if (string.IsNullOrEmpty(filterXml) == false)
            docFilter.LoadXml(filterXml); //ERROR THROWN HERE!!!

What should I change in my code to edit or parse filterXml? My filterXml looks like this:

<Testing>
<Test>CITY & COUNTY</Test>
</Testing>

I am changing my string value from & to &. Here is my code for that:

string editXml = filterXml;
    if (editXml.Contains("&"))
    {
        editXml.Replace('&', '&');
    }

But its giving me an err on inside the if statement : Too many literals.

About the second question: there are two signatures for String.Replace. One that takes characters, the other that takes strings. Using single quotes attempts to build character literals — but «&», for C#, is really a string (it has five characters).

Does it work with double quotes?

editXml.Replace("&", "&");

If you would like to be a bit more conservative, you could also write code to ensure that the &s you are replacing are not followed by one of

amp; quot; apos; gt; lt; or #

(but this would still not be a perfect filtering)
