Technical References - [xmlnodesattributes]

This context is used to iterate the attributes of a specific XML node.

[xmlnodesattributes ref=...&path=...] [/xmlnodesattributes]

The 'path' parameter is used to locate the node. As with the [xmlnodes] context, the 'path' parameter has three modes; 'named:', 'indexed:', and 'xpath:'.

Optional Tag Parameters:

· ref - Reference to an xml object variable. If this parameter is not provided, then it is assumed that there is an 'outer' [xmlnode/s] 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.

Optional Context Tags:

· [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.

Lets use the [xmlnodesattributes] context to retrieve the attributes of the first CD node of the example1.xml file...

[xmlparse var=xml_var1][include file=example1.xml][/xmlparse]

Attributes for the 'CD' node:
[xmlnode ref=xml_var1&path=indexed:1/1]
[content]
[/xmlnode]

Are...
[xmlnodeattributes ref=xml_var1&path=indexed:1/1]
[name]=[value]

[/xmlnodeattributes]

Results...

Attributes for the 'CD' 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>

Are...
id=123
status=instock

To simplify the code, we could place the [xmlnodesattributes] context 'inside' of the [xmlnode] context. In this case, we will not need to supply the 'path' or 'ref' parameters to [xmlnodesattributes], since it will use the 'implied' XML node in the outer [xmlnode] context.

We use...
[xmlparse var=xml_var1][include file=example1.xml][/xmlparse]

Attributes for the 'CD' node:
[xmlnode ref=xml_var1&path=indexed:1/1]
[content]

Are...
[xmlnodeattributes]
[name]=[value]

[/xmlnodeattributes]
[/xmlnode]

Results...

Attributes for the 'CD' node:
<CD status="instock" id="123">

<PRICE>10.90</PRICE>
