How to build an Xpath query in objective-c to get every TR except the first?
Currently the html I'm parsing looks something like this
NSString* markup = [NSString stringWithFormat:@"
<html>
<head>
<title>hi</title>
</开发者_StackOverflow社区head>
<body>
<table id='ctl00_ContentPlaceHolder1_dgAppointmentSearchResult'>
<tr>
<th>fail</th>
</tr>
<tr>
<td>1</td>
<td>2</td>
</tr>
<tr>
<td>3</td>
<td>4</td>
</tr>
</table>
</body>
</html>"];
Next I'm attempting to get each TR (so I can reach each #2 TD inside each TR) except the first TR has a TH inside it so I want to avoid this.
So far I have the following but notice it only pulls a specific TR / TD combo .. not each of them :(
NSData *data = [markup dataUsingEncoding:NSUTF8StringEncoding];
TFHpple* xpathParser = [[TFHpple alloc] initWithHTMLData:data];
NSArray *elements = [xpathParser search:@"
//table[
@id='ctl00_ContentPlaceHolder1_dgAppointmentSearchResult'
]/tr[2]/td[2]
"];
TFHppleElement *element = [elements objectAtIndex:0];
NSString *content = [element content];
[xpathParser release];
[data release];
Any help for an Xpath newbie?
You can use either:
//table[@id='ctl00_ContentPlaceHolder1_dgAppointmentSearchResult']/tr
[position() > 1]/td[2]
or even more semantic:
//table[@id='ctl00_ContentPlaceHolder1_dgAppointmentSearchResult']/tr
[not(th)]/td[2]
加载中,请稍侯......
