the caml query bellow don't return the correct result :
<Where><Eq><FieldRef Name='ParentLink' /><Value Type='Text'>ⵜⴰⵎⴰⵡⴰⵙⵜ</Value></Eq> </Where> i think the problem is due to the unicode charchter that i use to search. there is a solution to escape it ?
You need to surround the data with a CDATA tag:
<Value Type="Text"><![CDATA["ⵜⴰⵎⴰⵡⴰⵙⵜ"]]></Value> Try encoding the given string before passing it to the CAML query:
string EncodeForCAML(string s) { StringBuilder sb = new StringBuilder(); for (int i = 0; i < s.Length; ++i) { char ch = s[i]; if (char.IsLetterOrDigit(ch)) sb.Append(ch); else sb.AppendFormat("&#{0};", Convert.ToInt32(ch)); } return sb.ToString(); }
