我尝试使用 python 在 selenium RC 中进行验证: sel.is_element_present("//div[@id='USER_PHOTOS']/div[1]/span[1]/img) 但看起来无法正确。并尝试过这个: sel.is_element_present("//div[@id='USER_PHOTOS']) 它有效。有没有人为什么在这里找不到子标签:
<div class="bx01 deals swirllinks">
<div id="USER_PHOTOS" class="bx01">
<div class="ug_photos">
<span class="u_/LocationPhotos-g294212-d1234659-Fairmont_Beijing-Beijing.html#41195738 fkASDF fkLnk" onclick="setPID(3901); return ta.call('ta.overlays.Factory.photosLB', event, this);">
<img class="ug_photo" alt="coffee machine" src="http://ccm.ddcdn.com/ext/photo-l/02/5d/7c/f6/coffee-machine.jpg"/>
