Freemarker PDF/Email template list filter

I want to make a list of filtered items in Netsuite HTML/email template. Seems that this line of code wont work on it using freemarker.

<#assign xs = [1, -2, 3, 4, -5]>
Positives:
<#list xs?filter(x -> x > 0) as x>${x} </#list>
Negatives:
<#list xs?filter(x -> x < 0) as x>${x} </#list>

Could you guys give me some insights on how to achieve this? Thank you so much in advance! I'm a beginner and been searching this a lot and unfortunately no luck at all.

It looks like NetSuite is using FreeMarker v2.3.26 and the filter built-in was added in 2.3.29.

Here's one way to do it without filter:

<#assign xs = [1, -2, 3, 4, -5]>
<#assign xpos = []>
<#assign xneg = []>

<#list xs as x>
    <#if x gt 0>
        <#assign xpos = xpos + [x]>
    <#elseif x lt 0>
        <#assign xneg = xneg + [x]>
    </#if>
</#list>

Positives:
<#list xpos as x>${x} </#list>

Negatives:
<#list xneg as x>${x} </#list>
