将 XML 数据从 URL 写入 SSIS 脚本任务中的对象 [英] Writing XML data from URL to Object in SSIS Script Task

问题描述

我有这个包含 XML 数据的 URL.我必须从 URL 中提取该数据并将其转储到 DW 表中.我为此使用了 SSIS 脚本任务.

I have this URL where there is XML data. I have to extract that data from URL and dump it into DW table. I am using SSIS Script Task for that.

这是数据的样子:

-<货币>

<csymbol>AED</csymbol>

<cname>United Arab Emirates Dirhams</cname>

<crate>3.6732001305</crate>

<cinverse>0.2722421770</cinverse>

−

<csymbol>AFN</csymbol>

<cname>Afghanistan Afghanis</cname>

<crate>44.0000000000</crate>

<cinverse>0.0227272727</cinverse>

−

<csymbol>ALL</csymbol>

<cname>Albania Leke</cname>

<crate>104.4100000001</crate>

<cinverse>0.0095776267</cinverse>

这是我用来将其加载到某种对象类型或其他类型的代码.但我不知道该怎么做.

This is the code i'm using to load it into some Object type or something. But i dont know how to do that.

public void Main()
{
    String URLString = "http://www.xe.com/dfs/datafeed2.cgi?beeline";
    XmlDocument doc = new XmlDocument();
    XmlTextReader reader = new XmlTextReader(URLString);
    doc.Load(reader);

    XmlNodeList currencynodes = doc.SelectNodes("currency");
    foreach(XmlNode currency in currencynodes)
    {
        XmlNode csymbol = currency.SelectSingleNode("csymbol");
        string csymbolvalue = csymbol.Value;

        XmlNode cname = currency.SelectSingleNode("cname");
        string cnamevalue = cname.Value;

        XmlNode crate = currency.SelectSingleNode("crate");
        string cratevalue = crate.Value;

        XmlNode cinverse = currency.SelectSingleNode("cinverse");
        string cinversevalue = cinverse.Value;

        Dts.Variables["User::oCurrencyConversion"].Value = csymbol.Value;
    }

推荐答案

为此，您实际上需要在数据流任务中使用脚本源组件.然后使用标准的目标组件插入到 DW 中.

You actually need to use a Script Source Component inside of a dataflow task for this. Then use the standard destination compoents to do the insert into DW.

这是我实现的示例包.http://dl.dropbox.com/u/5332312/xRateLoader.zip
