XMLFind Example (Magic xpa 4.x)

<?xml version="1.0"?>

<order id="123">

<issued_by>

<name>John Smith</name>

<address>

<street>Somewhere</street>

<city>Nowhere</city>

</address>

</issued_by>

<item cat_num="2145451544">

<price>99.99</price>

<amount>2</amount>

</item>

<item cat_num="1384325456">

<price>19.99</price>

<amount>2</amount>

</item>

</order>

Given that the XML above is saved into the file C:\myxml.xml, and that the current task's first I/O device points to an XML file, the following expressions apply:

• XMLFind (0, 1, '/order/issued_by', 'name', 0, '', 'John Smith') returns 1.

• XMLFind (0, 1, '/order/issued_by', 'name', 0, '', 'John') returns 0 because there is no name element with the value John under the /order/issued_by path.

• XMLFind (0, 1, '/order', 'item', 1, 'cat_num', '1384325456') returns 2.

• XMLFind (0, 1, '/order', 'item', 1, 'cat_num', '12345') returns 0 because there is no item in the order with a catalog number that equals 12345.

• XMLFind (0, 1, '/order', 'item', 0, 'price', '99.99') returns 1.

• XMLFind (0, 1, '/order', 'item', 0, 'amount', '2', 2) returns 2.
