我有一个xml文件，它存储在窗口10的d:\中：

<?xml version="1.0" encoding="UTF-8"?>
<root>
    <ChainId>7290027600007</ChainId>
    <SubChainId>001</SubChainId>
    <StoreId>001</StoreId>
    <BikoretNo>9</BikoretNo>
    <DllVerNo>8.0.1.3</DllVerNo>
</root>

我已经安装了ElasticSearch，可以在http://localhost:9200/. 我已经安装了logstash并创建了logstash-xml.conf来接收上面的xml文件。在logstash-xml.conf中，配置如下：

input
{
    file
        {
            path => "D:\data.xml"
            start_position => "beginning"
            sincedb_path => "NUL"
            exclude => "*.gz"
            type => "xml"
            codec => multiline {
                    pattern => "<?xml " 
                    negate => "true"
                    what => "previous"
                }
        }
}

filter {

    xml{
        source => "message"
        store_xml => false
        target => "root"
        xpath => [
            "/root/ChainId/text()", "ChainId",
            "/root/SubChainId/text()", "SubChainId",
            "/root/StoreId/text()", "StoreId",
            "/root/BikoretNo/text()", "BikoretNo",
            "/root/DllVerNo/text()", "DllVerNo"
        ]
    }

    mutate { 
        gsub => [ "message", "[\r\n]", "" ] 
    }
}

output{

elasticsearch{
        hosts => ["http://localhost:9200/"]
        index => "parse_xml"
    }

    stdout
    {
        codec => rubydebug
    }
}

在命令行中运行此配置时，我看到以下内容：

但是，回到elasticsearch，我可以记录创建的索引，但看不到加载的xml数据。
