完整的功能需要加入4块代码到不同的位置：
一、
using System.Xml.XPath;
二、
actions.NewItem("加入四角号", "根据701/711$a内容, 创建905$e", "AddFourAngle", false);
三、
void AddFourAngle()

四、
class getSiJiaoHao
{
public string hao;
public char authorchar;
public void QuHao()
{
XPathDocument doc = new XPathDocument("http://localhost/Dp2LibraryWs/sijiaohao.xml");
XPathNavigator nav = ((IXPathNavigable)doc).CreateNavigator();
XPathNodeIterator iter = nav.Select("/Collection/Character[@char='" + authorchar + "']");
while (iter.MoveNext())
{
hao = iter.Current.Value;
}
}
}
说明：
1、配置字符串数组中分别对应责任者为：1字（如1234）、2字（如1313）、3字（如1311）、团体（如前四字1111）；
2、个人责任者多于4字、只取前3字 ；
3、团体责任者少于4字，按个人责任者的规则取号。
4、两字每个字取两位号。
5、三个字首字取两位号，2、3字各取一位号。
5、四个字各字取一位号。
这是普遍应用的规则，在这大规则下，具体取号位可以自行配置，比如我碰到过的有：{1234，1313，1311，1111}或{1234,1414,1411,1111}等，都是在这个原则下。
当然，也不排除有特殊嗜好的图书馆，非要把首字只取一位，尾字取三位，那以上代码就没办法了，只能请数字平台的老师们来量身定做代码了。
