xmlnodesattributes
The [xmlnodesattributes] context is used to iterate the attributes of a specific XML node.
Parameters
| Parameter | Description |
|---|---|
| ref | Reference to an xml object variable. If this parameter is not provided, then it is assumed that there is an 'outer' [xmlnode] or [xmlnodes] context from which to reference a particular XML node. |
| path | Path to the desired XML node. If an XPath expression is used, it should evaluate to a single node. |
Tags available within a [xmlnodesattributes] context:
| Tag | Description |
|---|---|
| name | The name of the current iterated XML node attribute. |
| value | The value of the current iterated XML node attribute. |
| index | The 'count' of the current iterated attribute. |
| numfound | The total 'count' of iterated attributes. |
The path parameter is used to locate the node. As with the [xmlnodes] context and the [xmlnode] context, the path parameter has three modes; named, indexed and xpath.
The [xmlnodesattributes] context is used to retrieve the attributes of an XML node, the attributes are the parameters of the XML node container.
Example WebDNA code:
This example uses an example file that you can view/download here example-file.xml
Parse the xml file:
Get the contents of the indexed node:
<CD status="instock" id="123">
<TITLE>Empire Burlesque</TITLE>
<ARTIST>Bob Dylan</ARTIST>
<COUNTRY>USA</COUNTRY>
<COMPANY>Columbia</COMPANY>
<PRICE>10.90</PRICE>
<YEAR>1985</YEAR>
</CD>
Display the attributes of the node:
id = 123
status = instock
To simplify the code, place the [xmlnodesattributes] context 'inside' of the [xmlnode] context. In this case, the 'path' or 'ref' parameters are not required [xmlnodesattributes], as the 'implied' XML node in the outer [xmlnode] context is used.
Example WebDNA code:
This example uses an example file that you can view/download here example-file.xml
id = 123
status = instock
The [xmlnodesattributes] context is used to retrieve the attributes of an XML node, the attributes are the parameters of the XML node container.
