Import XML with attributes into mysql - php

Question

I have a large (~30Mb) XML file like this:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<LIC Version="2.0" Title="Products">
<Item>
<Field Name="Filename">/root/_DOWNLOAD/Bird.txt</Field>
<Field Name="Read_By">Lisa Hannigan</Field>
<Field Name="Posit">Passenger</Field>
</Item>
<Item>
<Field Name="Filename">D:\03\Strypers.pdf</Field>
<Field Name="Read_By">Stryper</Field>
<Field Name="Intensity">2</Field>
<Field Name="IMG">78</Field>
<Field Name="Rotate">0</Field>
</Item>
<Item>
<Field Name="Filename">D:\Afriu.txt</Field>
<Field Name="Read_By">Africano</Field>
<Field Name="Posit">Canto Africano vol.1</Field>
<Field Name="File_Resource">mp3</Field>
</Item>
<Item>
<Field Name="Filename">D:\_VARIOUS\Knots.pdf</Field>
<Field Name="Date">40624</Field>
</Item>
...
</LIC>
I want to import this xml into mysql database, with a php script. I've used SIMPLEXML and xpath:
$url = 'FILE.xml';
$xml = simplexml_load_file($url);
$result = $xml->xpath("//Field[#Name]");
foreach { ... }
What do i need? What is the correct "foreach" to create an array to use for mysql sql?
Notes that every row (identify by "Item") is not same (not have the same "Field Name").
Is it correct to use simplexml for larger file?
Thank you for help!
update
This is an example to use "foreach", i tried:
$result = $xml->xpath("//Field[#Name]");
foreach($result as $key => $value) {
echo $value['Name']."=".$value.",";
}
Now I want to find out how to create the string to insert in mysql

Answer 1

First create a table that matches all possible fields as columns. Then you can load it by a LOAD XML LOCAL INFILE query.
LOAD XML LOCAL INFILE 'file.xml'
INTO TABLE person
ROWS IDENTIFIED BY '<Item>';

Answer 2

I try to answer my question.
<?php
$url = 'FILEXML';
$xml = simplexml_load_file($url);
$i = 1;
foreach($xml->xpath("/LIC/Item") as $docs)
{
foreach($docs->Field as $field)
{
$resultstr[] = $field["Name"];
}
$sql_head = headquote($resultstr);
$sql_ins = "INSERT INTO table_name (";
$sql_dec = ") VALUE (";
unset($resultstr);
$fresult = (array)$docs;
$fvalue = array_pop($fresult);
$sql_val = numking($fvalue);
$sql_end = ");";
$query_to_use_for_mysql = ($sql_ins.$sql_head.$sql_dec.$sql_val.$sql_end);
unset($fresult);
unset($fvalue);
}
?>
And add this two functions:
<?php
function headquote($hdarray) {
$hdata = array();
foreach ( $hdarray as $hdval ) {
# Use backticks instead quotes!
$hdata[] = "`$hdval`";
}
$hdarray = implode($hdata, ',');
return $hdarray;
}
function numking($input) {
$data = array();
foreach ( $input as $value ) {
$data[] = is_numeric($value) ? $value : "'".mysql_escape_string($value)."'";
}
$input = implode($data, ',');
return $input;
}
?>
Thanks to all for help!

Answer 3

$url = 'FILE.xml';
$xml = simplexml_load_file($url);
for($i=0;$i<count($xml->Item);$i++)
{
print_r($xml->Item[$i]);
}
