Xpath rules - contains() not returning what I'd like -


so far have following xpath set pull word 'gallery' href returns entire url instead of word gallery. explain i'm doing wrong please? you, it's appreciated!

$x("//link[@rel='canonical' , contains(@href,'gallery')]")

your current xpath expression,

$x("//link[@rel='canonical' , contains(@href,'gallery')]")

returns sequence of <link> elements. depending on way evaluate them, might getting text content.

if want word 'gallery', in xpath 2.0 can say

$x("//link[@rel='canonical' , contains(@href,'gallery')]/'gallery'")

which return sequence of strings, 1 'gallery' each <link> element fulfills predicate.

or 

$x("if (exists(//link[@rel='canonical' , contains(@href,'gallery')]))        'gallery' else null")

which return either 'gallery' (once), or null.

c++ - End of file on pipe magic during open -

i have c++ application in starting process(wireshark) following. if (fp == null){ fp = popen(processpath, "r"); //processpath process want start if (!fp){ throw std::invalid_argument("cannot start process"); } fprintf(fp, d_msg);//d_msg input want provide process } else if(fp != null){ fprintf(fp, d_msg); } the problem when execute c++ application, start wireshark error end of file on pipe magic during open what should avoid that? also tried using mkfifo create named pipe , execute it. used this: if (fp == null){ system("mkfifo /tmp/mine.pcap"); fp = popen("wireshark -k -i /tmp/mine.pcap", "r"); if (!fp){ dout << "cannot start wireshark"<<std::endl; throw std::invalid_argument("cannot start wireshark"); } input = fopen("/tmp/mine.pcap", "wb"); fprintf(input , d_msg); fclose(input)...

data.table making a copy of table in R -

i doing this: myfun <- function(inputvar_vec){ # inputvar_vec input vector # # result = output vector return(result) } dt[, result := lapply(.sd, myfun), = byvar, .sdcols = inputvar] i getting following warning: warning message: `in `[.data.table`(df1, , `:=`(prop, lapply(.sd, propeventinlastk)), : invalid .internal.selfref detected , fixed taking copy of whole table, := can add new column reference. @ earlier point, data.table has been copied r (or been created manually using structure() or similar). (and more stuff) .... ` my guess because stacking result vectors (after operation), copy being made? can suggest method remove warning? have done using apply functions , thought should extendable here too. my other question is: can pass chunk of rows data frame (subsetted using statement), , call function myfun operate on that? adding example requested # generate data n = 10000 default=na value = 1 df = data.table(id = sample(1:5000, n, replace=true), ...
