尽管在以下代码中使用了SaveOptions.DisableFormatting选项:

XDocument xmlDoc = XDocument.Load(FileManager.SourceFile); 
string element="campaign";
string attribute="id";

var items = from item in xmlDoc.Descendants(element)                        
            select item;

foreach (XElement itemAttribute in items)
{
    itemAttribute.SetAttributeValue(attribute, "it worked!");
    //itemElement.SetElementValue("name", "Lord of the Rings Figures");
}

xmlDoc.Save(TargetFile, SaveOptions.DisableFormatting);

目标XML文件将其添加到它:

<?xml version="1.0" encoding="utf-8"?>

有没有办法保留原始格式,并没有添加版本和编码信息？

目前我的代码导致间歇性的ConcurrentModificationException错误,可能是因为我循环遍历HashMap的方式:

for (Map.Entry<String, Entity> entry : entities.entrySet()) {
    String key = entry.getKey();
    Entity item = entry.getValue();
    if (item.isDestroyed()){
        entities.remove(key);
        ViewManager.getInstance().removeItem(key);
        //INSTRUCT THE ENTITY TO PERFORM IT'S DESTROYED BEHAVIOR item.Destroyed()                    
    } else {
        item.update(1);
        ConsoleItem ci = new ConsoleItemImpl(item.getIdentifier(), item.getLocation(), ColorStringConverter.getInstance().StringToColor(item.getSide()), item.getAngle(), item.getShape(), item.toString(), item.isDestroyed(), item.isDamaged());
        ViewManager.getInstance().updateItem(ci);                    
    }

    item.update(1);
}
// updateInfo call
ViewManager.getInstance().updateInfo(summary());
}

如何通过HashMap连续循环并避免出现ConcurrentModificationException错误？
