use "let" to extract "TEXT" body

[fitnesslover]

I am trying to extract a value from the body of html type that I specifies the RestFixture to treat as "TEXT" format. Below are the steps. However, I keep getting the error message saying "last response body cannot be parsed" in the "let" step.

!|smartrics.rest.fitnesse.fixture.RestFixtureConfig|
| restfixture.content.handlers.map | text/html=TEXT|

!|smartrics.rest.fitnesse.fixture.RestFixture|some URL |
|GET| some API | 200 |text/html |name="id" value="|
|let|id|body|name="id" value="(.*)"||

Is it the case that "let" can only extract from XML? If so, how can I get about getting the value from a html body?

Yes, at the moment the let body type adapter expects the body in XML.
To work around this, at the moment you have to use the JS type adapter.

For example:

!|smartrics.rest.fitnesse.fixture.RestFixture|http://www.fitnesse.org |
|GET| / | 200 |Content-Type: text/html |id="addChildPopup" class="popup_window" |
|let|id|js|response.body.match(/id="(.*)" class="popup_window"/)[1]||

should successfully assign to id the value of addChildPopup

in essence, the JS let body type adapter allows you to write javascript expressions whose return value is assigned to the let label. You have your response body in the global variable response.body
