I am running the ant ramDownloadAsset.xml script to download the RAM asset. I would like to amend the script to download asset only if a condition of one of the asset attributes is met (eg. sequence=1) and need some help on how to change the script. I was not able to add <ram> as I cannot set the value of the attribute.

<target>
<echo>
<mkdir>
<ram>
<ram>
</ram>
</target>
Thanks.

The XML didn't render properly, so I'm not entirely sure what you're trying to do. If you're using the web interface for the forum, check the "Disable HTML in this post" checkbox when you enter HTML/XML.

What you want to accomplish is technically possible using the <ram:propertyHelper /> tag, but it's pretty limited in practice. Here's what you could do (note the <if>, <then> and <equals> tags are from the Ant-Contrib project):

<ram:propertyHelper />
<ram:server id="ramServer" url="..." username="..." password="..." />
<ram:asset id="myAsset" server="ramServer" guid="..." version="..." />
<if>
<equals arg1="${myAsset.assetAttributes.values}" arg2="1" />
<then>
<ram:download server="ramServer">
<ram:asset refid="myAsset" />
</ram:download>
</then>
</if>

This assumes the attribute you want is the first (or only) attribute in the list... and by this, I don't mean the first attribute you see in the web UI... it's the first attribute in the list returned by the Java API. This is the limited part I was talking about. You can't currently get an attribute by name. This is something we'd like to add at some point.

Hi,

I tried to echo ${myAsset.assetAttributes.values} but the the output is this property has not been set.
I thought I have created the attribute in RAM. What could be wrong here?

Thanks for your help!

This script worked for me:

<project default="test" xmlns:ram="antlib:com.ibm.ram.ant">

	<target name="test">

		<ram:propertyHelper />

		<ram:server id="ramServer" url="http://localhost:8080/ram/" username="admin" password="admin" />

		<ram:asset id="myAsset" server="ramServer" guid="A6EAAFE9-A685-5B15-1C07-B45FF5615CD6" version="1.0" />

		<echo>${myAsset.assetAttributes[0].values[0]}</echo>

	</target>

</project>

That asset had one simple text attribute and the script echoed its value.

What version of Ant are you using? What version of RAM?

Ah... Ant 1.8 is not supported in RAM 7.5.0.1, because Ant's property helper stuff was all completely redone. As a matter of fact, in RAM 7.5.0.2, we throw an error if you're not using Ant 1.7.x. Try your script with Ant 1.7.x and it should work.

I wanted to suggest getting the attribute this way, but there's a bug causing it not to work:

<ram:propertyHelper />

<ram:server id="ramServer" url="http://localhost:8080/ram" username="admin" password="admin" />

<ram:asset server="ramServer" guid="EC7CCE13-7301-13B3-72CB-6069B9398CC8" version="1.0">

	<ram:attribute id="myAttr" name="Line Of Business" />

</ram:asset>

<echo message="${myAttr.name}: ${myAttr.values[0]}" />

It will be fixed in the next 7.5.1 build, but for 7.5.0.x it won't work. I don't think there's any way to loop through and find the attribute you want.
