[TYPO3-english] retrieve IDs of content items in FCE?

No problem, you can make use of the stdWrap capabilities of XPATH's
source property and retrieve the FCE id dynamically with a CONTENT cObject:

page.10 = XPATH
page.10 {

  # fetch XML field from FCE on current page
  source.cObject = CONTENT
  source.cObject {
    table = tt_content
    select {
      where = CType='templavoila_pi1'
      andWhere = tx_templavoila_ds=###FCE_DS_ID###
      max = 1
      selectFields = tx_templavoila_flex
    }
    renderObj = TEXT
    renderObj.field = tx_templavoila_flex
  }

  # set expression and return format
  expression = //field[@index="###YOUR_FIELDNAME###"]/value
  return = string

  # result object from XPATH query
  resultObj {
    cObjNum = 1
    1.current = 1
  }
}

Since the scope of the CONTENT cObject is always the current page (if
not set otherwise with pidInList) you always get the first FCE on your
(copied) pages. The andWhere part above is optional but helps in
narrowing down the possible results to a specific FCE type. If that is
not enough, try to find the FCE type you are targeting with phpMyAdmin
in the table tt_content and check which fields you could use in your
specific setup to only select FCEs you want.

Cheers,
Torsten
