Iterate over YAML tree and extract elements when converting to another format (e.g. DOCX or PDF)

Iterate over YAML tree and extract elements when converting to another format (e.g. DOCX or PDF)

Is it possible to iterate over a YAML file containing the elements I want 
converted into another format?

Here is a snippet of my current YAML structure (it is in YAML so that I can 
use it in other ways later - such as with R)

---
Items:
  "@Kamieniecki_Prevalencepsychologicaldistress_2001":
    Focus:  "Prevalence of psychological distress or disorders in young 
people who are homeless in Australia"
    Number of studies:  14
    Reported findings:  "Young people who are homeless have high rates of 
psychological disorders and score higher on tests of psychological distress"
    Reference: "@Kamieniecki_Prevalencepsychologicaldistress_2001"
    Tags:
      - negative_outcomes
      - mental_health

  "@EmbletonMwangiEtAl_epidemiologysubstanceuse_2013":
    Focus: "Prevalence of lifetime substance use in children living on the 
street in 'resource constrained settings'"
    Number of studies: 50
    Reported findings: "Pooled prevalence estimate of 60% [95% CI: 51-69%]"
    Reference: "@EmbletonMwangiEtAl_epidemiologysubstanceuse_2013"
    Tags:
      - negative_outcomes
      - substance_use
...

Is it possible to get pandoc (or a pandoc filter) to iterate over each of 
the items and extract specific elements (perhaps even conditionally - e.g. 
only those with certain tags)?

Brendan.

[John MacFarlane]

If you're targeting PDF, yes, this is easy, you can just
create a custom latex template and use the iteration commands
($for$) provided in the template language.

For Docx, you'd need to write a filter, because there is
no template.
