Normally you can select all targets with group select. For complex selections, you can input XPath manually, here's a basic tutorial of XPath:
I can't select all the contents I want to scrape.įMiner locate the targets with XPath and Postion, see select target. FMiner run the re string with javscript fuction RegExp.match with parameter " igm", and you must make sure the string is correct. Like normal scraping action, add scrape page and capture content actions, then change extract type to regular expression, input the re string to the control. For scrape the email address.īecause FMiner will run the re string for the target html code, you should keep target xpath to /html for the whole page.

#FMINER BUTTON CODE#
Please change "extract type" to "DOM attribute" -> "inner text" to try, if can't work, you have to change "extract type to "html source" to scrape the source code of DOM. You can use runjs action, and with code: () If the links is ajax button, see this post . If the links is the real links and can be used with "openlink(s)", you can select all pages links(2,3.) as the next links, FMiner will open this links recursively not duplicate.Ģ. If it's a "next page" link, see this tutorial for a loop: . You should use "click" action for the link. If you encounter this error when use "open link" action to open a link, means the link is not a real link, it's a button for ajax/javascript.

Now the xpath should be like "xxxxx/xxxx/tr".Ĥ. Click "select target", and select a "td" target in table on page. Select the "scrape page" node in scene, check "Extract multiple sets of data", because you want to scrape multiple row data.Ģ.
So you shoud select a "td" and then use "expand select" to select a "tr". The only different is row in table is DOM "tr", and it's invisible, and can't be selected by clicking it on page. You should select every row in table in "scrape page" node with "group select", then add "capture content" to capture every field in rows. Here is no much different as this tutorial Scrape multiple sets of data from a yellow page . This page is outdated, please go to here for new documentation!
