• When applied to XML, which is technically case sensitive, the Dot Operator is still case insensitive. If you wish to

perform a case-sensitive XML operation, use the member functions of the roXMLElement/roXMLList objects.

Attribute Operator

The “@” Attribute Operator can be used with an roXMLElement instance to return a named attribute. Though XML is case

sensitive, the Attribute Operator is always case insensitive. If the Attribute Operator is used with an roXMLList instance, it

will only return a value if that list contains exactly one element.

Examples

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

<photo id="3131875696" owner="21963906@N06" secret="f248c84625" server="3125"

farm="4" title="VNY 16R" ispublic="1" isfriend="0" isfamily="0" />

<photo id="3131137552" owner="8979045@N07" secret="b22cfde7c4" server="3078"

farm="4" title="hoot" ispublic="1" isfriend="0" isfamily="0" />

<photo id="3131040291" owner="27651538@N06" secret="ae25ff3942" server="3286"

farm="4" title="172 • 365 :: Someone once told me..." ispublic="1" isfriend="0"

</photos>

</rsp>

Given the XML in the above example.xml file, then the following code will return an roXMLList instance with three entries:

rsp=CreateObject("roXMLElement")

rsp.Parse(ReadAsciiFile("example.xml"))

? rsp.photos.photo

1 2 ... 19 20 21 22 23 24 25 26 27 28 29 ... 74 75
