Question

I have a string in linq which is loaded from xml, that attribute or element is optional, but I want to trim the string because the xml file can be written manually like this.

<text>Hello World</text>

or like this

<text>
    hello world
<text>

the later will create the new line characters before and afterwards which i want trimming.

I tried to do

QuestionText = (string)query.Element("text").ToString().Trim()

but that crashes the app when that element is not present.

Answer 1

QuestionText = query.Element("text")!=null ? query.Element("text").Value.Trim() : string.Empty;
