Configure Windsor IoC from XML file - special chatracters in value of XML element

StackOverflow https://stackoverflow.com/questions/9556545

Question

I use Castle Windsor IoC. I would like configure object in IoC from XML file. Class is only POCO with some properties.

My problem is that value of property is string which contain special characters.

For example here is XML which I use for configure object in IoC.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <components>
    <component id="pokecUrls" 
               type="Pk.Common.Entities.Communication.PkcUrls, Pk.Common" 
               lifestyle="singleton">
      <parameters>

        <LogOn>https://pk.zet.com/overenie?isWap=0&uri=http%3A%2F%2Fpk.zet.com%2F</LogOn>

      </parameters>
    </component>
  </components>
</configuration>

Here is C# code:

_container.Install(Configuration.FromXmlFile("PkcCoreSettings\\PkUrls.xml"));
var urls = _container.Resolve<Pkrls>();
Assert.IsNotNull(urls);

This code crash because element LogOn contains string with specials characters.

I get this error:

{"Error processing node resource FileResource: [PkUrls.xml] [filepath]"}

InnerException:

{"An error occurred while parsing EntityName. Line 11, position 61."}

StackTrace:

It exist way how can I have special characters in value of XML element and use this XML file for confirure Windows IoC?

I am not sure if it is possible

Was it helpful?

Solution

You need to escape the & as &amp;, because & is special character in XML:

<LogOn>https://pk.zet.com/overenie?isWap=0&amp;uri=http%3A%2F%2Fpk.zet.com%2F</LogOn>

Alternatively, you could write it as CDATA:

<LogOn><![CDATA[https://pk.zet.com/overenie?isWap=0&uri=http%3A%2F%2Fpk.zet.com%2F]]></LogOn>

There are no other characters in that URL that are special in XML.
