Pulling one value from XML in MSSQL - php

Question

I have the following XML all contained in one cell in a MSSQL DB:
<receipt reference="INT000003" major="2" minor="14.804" beta="">
<dates id="Booking Dates">
<item id="Date of Booking">23 May 2013 - 17:09</item>
</dates>
<advertisement id="advertisement details">
<item id="Booked by">Mr System Administrator</item>
<item id="Brand or Product">Testing</item>
<item id="Priority">500</item>
</advertisement>
</receipt>
I want to get the value <item id="Brand or Product">Testing</item> out of that cell (specifically "Testing" though) to use in a PHP based webpage. Does anyone know of any PHP to read this type of XML and search for values?
Thanks.

Answer 1

You can use DOMXPath::query for it in PHP. First select the entire XML from the table as you normally would and then get the correct elements.
<?php
$xml = <<<END
<receipt reference="INT000003" major="2" minor="14.804" beta="">
<dates id="Booking Dates">
<item id="Date of Booking">23 May 2013 - 17:09</item>
</dates>
<advertisement id="advertisement details">
<item id="Booked by">Mr System Administrator</item>
<item id="Brand or Product">Testing</item>
<item id="Priority">500</item>
</advertisement>
</receipt>
END; //you would load it from the table
$dom = new DOMDocument;
$dom->loadXML($xml);
$xpath = new DOMXPath($dom);
$query = "//advertisement/item";
$items = $xpath->query($query);
foreach ($items as $item) {
echo $item->nodeValue;
}
?>
This will output
Mr System Administrator
Testing
500
And if you would need the value of a specific ID you can use
<?php
$dom = new DOMDocument;
$dom->loadXML($xml);
$xpath = new DOMXPath($dom);
$query = "//advertisement/item[#id='Brand or Product']";
$items = $xpath->query($query);
foreach ($items as $item) {
echo $item->nodeValue;
}
Output:
Testing

This can also done in SQL as below :
declare #xml xml =
'<receipt reference="INT000003" major="2" minor="14.804" beta="">
<dates id="Booking Dates">
<item id="Date of Booking">23 May 2013 - 17:09</item>
</dates>
<advertisement id="advertisement details">
<item id="Booked by">Mr System Administrator</item>
<item id="Brand or Product">Testing</item>
<item id="Priority">500</item>
</advertisement>
</receipt>'
select #xml.value
('(/receipt/advertisement/item[#id="Brand or Product"])[1]', 'nvarchar(100)')
Also, you can directly fetch the value from table as below :
select cast(YOUR_COLUMN_NAME as XML).value('(/receipt/advertisement/item[#id="Brand or Product"])[1]', 'nvarchar(100)')
as s from YOUR_TABLE_NAME
