【轉】org.jdom.IllegalDataException: The data ""is not legal for a JDOM attribute: 0xb is not a legal 異常

今天用jdom生成xml，在操作中出現了 org.jdom.IllegalDataException: The data ""is not legal for a JDOM attribute: 0xb is not a legal 異常，仔細跟蹤發現，在原有的組建對象的屬性中出現了異常字符，通過下面的替換，再重新轉換成String,trim后正常。

 char [] xmlChar = paragraph.toCharArray();  
    for (int i=0; i < xmlChar.length; ++i) {  
    if (xmlChar[i] > 0xFFFD)   
    {   
       //直接替換掉0xb   
        xmlChar[i] =' ';  
    }   
    else if (xmlChar[i] < 0x20 && xmlChar[i] != 't' & xmlChar[i] != 'n' & xmlChar[i] != 'r')  
    {  
       //直接替換掉0xb  
        xmlChar[i] =' ' ;  
    }  
    }
