Ironpython& C＃：没有名为.....的模块 [英] Ironpython & C# : no module named .....

问题描述

Hello All，



我目前正在尝试在c＃中集成python脚本。此脚本的目标是解析xml数据。我在下面给出了我的代码。所以每当我运行项目时，我都会得到以下错误：错误：没有名为xml.parsers.expat的模块

如果我使用minidom / ElementTree错误将是相同的



Program.cs

Hello All,

I'm currently trying to integrate python script in c#. Goal of this script is to parse the xml data. I have given my code below. So whenever I run the project I get below error:Error:No module named xml.parsers.expat
The error will be same if I use minidom/ElementTree

using IronPython.Modules;
using IronPython.Runtime;
using IronPython.Compiler;
using IronPython.Zlib;
using IronPython.SQLite;

namespace PyCsharpApp3
{
    class Program
    {
        static void Main(string[] args)
        {
            var ipy = Python.CreateRuntime();
            dynamic test = ipy.UseFile("Test.py");
            test.start_element();
            Console.ReadLine();
        }
    }
}

test.py
--------

import xml.parsers.expat


# 3 handler functions
def start_element(name, attrs):
    print('Start element:', name, attrs)
def end_element(name):
    print('End element:', name)
def char_data(data):
    print('Character data:', repr(data))

p = xml.parsers.expat.ParserCreate()

p.StartElementHandler = start_element
p.EndElementHandler = end_element
p.CharacterDataHandler = char_data

p.Parse("""<?xml version="1.0"?>
<parent id="top"><child1 name="paul">Text goes here</child1>
<child2 name="fred">More text</child2>
</parent>""", 1)

推荐答案

IronPython实现没有附带 xml.parsers.expat 。但是，有一种解决方法。有一个项目 FePy [ ^ ]为IronPython提供增强功能。而xml.parsers.expat就是其中之一。下载此expat实施文件 [ ^ ]并将其复制到您的IronPython安装文件夹中的Lib\xml\parsers\expat.py 。

The IronPython implementation does not come with xml.parsers.expat. However, there is a workaround. There is a project FePy[^] that provides enhancements for IronPython. And xml.parsers.expat is one of them. Download this expat implementation file[^] and copy it to Lib\xml\parsers\expat.py in your IronPython installation folder.
