I am trying to write a xychange transformation that matches on an em-dash that is preceded or followed by a space and outputs an em-dash without the space. Transforming Data doc (Table 3-2) shows several ways to represent an em-dash but I can't get my match to recognize any of them. Seems simple enough but apparently too tough for me... Can anyone help?
What does the input that the match is not recognizing look like?
Here's the whole story.
We got this request from a client at ETS: "We would like XPP to explore a solution that would ensure spaces appear where required. Specifically, we would always want there to be a space between immediately adjacent end and start focus tags. There would be only one exception: when such appear directly before or after an em dash, no space should be inserted.
RULE 1) I wrote a rule which looks for <focus_end><focus_start> tags that have no space between them and adds a space. This works:
Match: <focus_end focus_idref="*"/><focus_start focus_id="*" itemref="*"/>
Output: <focus_end focus_idref="*"/> <focus_start focus_id="*" itemref="*"/>
To handle the exceptions I wrote two rules where the Match and the Output are the same.
RULE 2) This rule is for when the tags are preceded by an em-dash:
Match: \M<focus_end focus_idref="*" focus_number="*"/><focus_start itemref="*" focus_id="*" focus_number="*"/>
Output: \M<focus_end focus_idref="*" focus_number="*"/><focus_start itemref="*" focus_id="*" focus_number="*"/>
RULE 3) and this rule is for when the tags are followed by an em-dash:
Match: <focus_end focus_idref="*" focus_number="*"/><focus_start itemref="*" focus_id="*" focus_number="*"/>\M
Output: <focus_end focus_idref="*" focus_number="*"/><focus_start itemref="*" focus_id="*" focus_number="*"/>\M
Rules 2 and 3 do not work. Eventually I realized my rules were not recognizing an em-dash. So I tried this:
RULE 4)
Match: \M
Output: \M<^!--em dash-->
...and that does not work.
