I have a xml like this in string variable ( load from file )
<Data>
<Name>Test & < test> </Name>
</Data>
when i try to load this xml i got exception "an error occured while parsing Node". i think this is due to & in Name tag. I have search on the internet but all solutions (e.g. SecurityElement.Escape) escape main xml elements too like greater than to gt and less than to lt and i only want to replace & in my case. i can iterate through xml and replace only data part but is there any shortest way ?
AngleSharp has an error correcting "XML" parser that works more like an HTML5 or tag soup parser trying to correct and fix such markup errors. For your sample
using System;
using AngleSharp.Xml;
using AngleSharp.Xml.Parser;
namespace AngleSharpMalFormedXmlTest1
{
class Program
{
static void Main(string[] args)
{
var malFormedXml = @"<Data>
<Name>Test & < test> </Name>
</Data>";
var doc = new XmlParser(new XmlParserOptions() { IsSuppressingErrors = true }).ParseDocument(malFormedXml);
Console.WriteLine(doc.ToMarkup());
}
}
}
I get
<Data>
<Name>Test &< test> </Name>
</Data>
But once you open up your input to such kind of mal-formed XML you can easily run into misconceptions and incompatibilities or tool-dependency which using a W3C standard like XML was meant to avoid.
Since you have no control over the source, you could try some regex to make it a valid xml:
string xml = @"<Data>
<Name>Test & test& &1 <aaa &</Name>
</Data>";
xml = Regex.Replace(xml,@"&(?!\w+;)","&");
this will return
<Data>
<Name>Test & test& &1 <aaa &</Name>
</Data>
The presented XML is not well-formed.
You can use CData section to make your XML well-formed.
<Name> should become <Name><![CDATA[</Name> should become ]]></Name>well-formed XML
<Data>
<Name><![CDATA[Test & < test> ]]></Name>
</Data>
