如何使用 mysql LOAD XML LOCAL INFILE 导入 xml 文件

Question

我需要帮助将 xml 文件导入表，xml 文件有数百万条记录。

首先我使用的是simplexml_load_file，然后放一个循环来逐个插入记录，这需要很多时间。我已经使用了 csv 的 infile 并且效果很好，任何人都可以帮忙，我怎样才能对 xml 做同样的事情。

我正在尝试

LOAD XML LOCAL INFILE "C:/xampp/htdocs/class/on_the_list.xml" INTO TABLE tbl_juju ROWS IDENTIFIED BY '<job>' 

运行此查询会显示“MySQL 返回了一个空结果集（即零行）” 并且没有插入任何记录。下面是xml格式。

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

试试这个

LOAD DATA LOCAL INFILE 
    '".$path."'
    INTO TABLE 
    tbl_juju
    CHARACTER SET 'utf8'
    LINES STARTING BY '<job>' TERMINATED BY '</job>'
    (@tmp)
    SET
    id      = ExtractValue(@tmp, '//id'),
    employer = ExtractValue(@tmp, '//employer'),
    title = ExtractValue(@tmp, '//title'),
    description = ExtractValue(@tmp, '//description'),
    postingdate = ExtractValue(@tmp, '//postingdate'),
    joburl = ExtractValue(@tmp, '//joburl'),
    location_city = ExtractValue(@tmp, '//location_city'),
    location_state = ExtractValue(@tmp, '//location_state'),
    category = ExtractValue(@tmp, '//category'),
    vin = ExtractValue(@tmp, '//vin'),
    location = ExtractValue(@tmp, '//location')
