Function getAttribute
This function is part of the StAX support.
Name
hasNext returns true if the StAX stream has a pending next event (optionally of the requested type and name).Synopsis
getAttribute( $event name )Description
getAttribute returns the string value of an attribute.
The $event argument must be a START_ELEMENT event returned from nextEvent.
The name argument is the name of attribute, it can be a string or a QName.
Strings are interpreted as either a no-namespace local name, or in ClarkNotation.
To use the StAX functions you need to import them into either the global namespace or a local namespace.
Its recommended that you use a local namespace so that there is less chance of name collisions.
Example: process every START_EVENT for element named "element" and print the attribute value for "attr"
Given an xml file "file.xml"
<file>
<element attr="attr1"/>
<element attr="attr2">String</element>
</file>
<element attr="attr1"/>
<element attr="attr2">String</element>
</file>
import commands stax=stax reader=stax:newEventReader( file.xml ) while [ stax:hasNext( $reader START_ELEMENT element ) ] ; do event=stax:nextEvent( $reader ) ; attr=stax:getAttribute( $event attr ) echo $attr done stax:closeReader $reader
Result
