space in attributes

Here we see that there is no way to differentiate declare option db:parser "html"; "SPACE", doc("http://eaip.caa.gov.tw/eaip/history/2013-05-02-AIRAC/html/eAIP/RC-ENR-3.3-en-TW.html")//*[@class="Table-row-type-2 "] ,"NO SPACE", doc("http://eaip.caa.gov.tw/eaip/history/2013-05-02-AIRAC/html/eAIP/RC-ENR-3.3-en-TW.html")//*[@class="Table-row-type-2"] even though the source contains both. OK, this was probably intended.
