Likely bug in trxgrep #13

Closed kaby76 closed 2 years ago

kaby76 commented 3 years ago

Create the expression grammar (mkdir foo; cd foo; trgen; cd Generated; make).
Create input file "in.txt" with 1+2+3+4+5+6+7+8+9
Run: trparse in.txt | trxgrep ' count(//SCIENTIFIC_NUMBER/ancestor::*)'

Note, the xpath implementation doesn't have a way to create a tuple, so I can't do a count, and also return the node. That's a failure in xpath2 and I don't think it's available in xpath3.

This crashes in trxgrep. If I remove the function call "count()", it works.

Using the Arithmetic expression grammar, I can now print out the trees that have a certain depth:

trparse in.txt | trxgrep ' //SCIENTIFIC_NUMBER[count(ancestor::*) > 45]' | trtree

Basically, a problem in XSInteger parsing a string value. Fixed in the next release.

Fixed in v0.12.0
