xpath - HTMLAgilitliyPack: select Form input subnodes not working -
form:
<form method="post" name="contactform" action="form-handler.php"> <label for='name'>name:</label> <input type="text" name="name" /> <label for='email'>contact number:</label> <input type="text" name="phone" /> <label for='phone'>email:</label> <input type="text" name="email" /> <label for='message'>requirements:</label> <textarea name="message"></textarea> <input type="submit" value="submit" name="submit" class="quotebutton" /> </form> code:
htmlnode.elementsflags.remove("form"); htmlnodecollection fromnodes = doc.documentnode.selectnodes("//form"); foreach (htmlnode formnode in fromnodes) { var inputs = formnode.selectnodes(".//input"); } "//input" works , when check children xpath see:
/html[1]/body[1]/div[1]/div[3]/div[2]/div[1]/div[1]/input[2] which means, according hap, form doesn't include input!
".//input" selects subnodes of current formnode doesn't work (returns null)!
how fix added following doesn't work
htmlnode.elementsflags.remove("form"); any idea?
edit (+example):
in next sample inputs variable null.
var doc = new htmldocument(); doc.loadhtml(@" <!doctype html> <html> <head> <title>form test</title> </head> <body> <form> <input type=""text"" /> <input type=""reset"" /> <input type=""submit"" /> </form> </body> </html> "); htmlnode.elementsflags.remove("form"); ienumerable<htmlnode> fromnodes = doc.documentnode.descendants("form"); foreach (htmlnode formnode in fromnodes) { var inputs = formnode.selectnodes(".//input"); }
solved!
htmlnode.elementsflags.remove("form"); should called before loading document.
my bad :d
