XMLStreamException on import-graphml - neo4j

I exported the neo4j-database in graphml using neo4j-shell-tools format but while importing back the database at the production server I am getting the following error.
XMLStreamException: ParseError at [row,col]:[2542885,95] Message: An
invalid XML character (Unicode: 0x8) was found in the element content
of the document.
But there is no such character on line number 2542885.
I even deleted this line using sed -i (2542885d) but I am still getting the same error at the same line while importing. Strange.
It seems the line number which sed is referring to is not the same as the line at which the error is been thrown.
Please help out, I have spent a day to resolve this error. But no success.


Thank you. Error resolved.
I used xmllint, which gave the same error at another line number, and replacing that unicode character resolves the issue.

neo4j-admin import "Multi-line fields are illegal"

I'm getting the following error in Neo4j community 4.1.2 using the neo4-admin import tool.
Caused by:ERROR in input
data source: BufferedCharSeeker[source:/home/ubuntu/workspace/neo4j-community-4.1.2/bin/../import/nodes.csv, position:24455, line:359]
in field: code:string:6
for header: [id:ID, labels:LABEL, type:string, flags:string, lineno:string, code:string, childnum:string, funcid:string, classname:string, namespace:string, endlineno:string, name:string, doccomment:string]
raw field value: 402
original error: At /home/ubuntu/workspace/neo4j-community-4.1.2/bin/../import/nodes.csv # position 24455 - Multi-line fields are illegal in this context and so this might suggest that there's a field with a start quote, but a missing end quote. See /home/ubuntu/workspace/neo4j-community-4.1.2/bin/../import/nodes.csv # position 24455.
I checked each single byte with hexedit:
the line #359
the char #24455
the line #358
the line #360
357,AST,string,,34,"/load.php",1,310,,"",,,
358,AST,AST_CALL,,37,,9,310,,"",,,
359,AST,AST_NAME,NAME_NOT_FQ,37,,0,310,,"",,,
360,AST,string,,37,"wp_check_php_mysql_versions",0,310,,"",,,
361,AST,AST_ARG_LIST,,37,,1,310,,"",,,
362,AST,AST_INCLUDE_OR_EVAL,EXEC_REQUIRE,40,,10,310,,"",,,
This is the absurd situation:
no multi-line fields are present
no special char are present
no extra 0A byte
no extra "start quote" without its relative "end quote"
I found some issues on Github but are referred to old versions of Neo4j...what can be the reason?

Finally I found the line causing the exception.
The exception cause was correct but the number of the line was totally wrong.
I pointed out it by adding the following flag --multiline-fields=true to the neo4j-admin import command.

Xcode Info.plist error: Consecutive statements on a line must be separated by ';' but looks like valid XML

Why is Xcode giving me errors on my Info.plist file?
The first error is on the first line (which I had nothing to do with writing.)
The first line is:
<?xml version="1.0" encoding="UTF-8"?>
and the error given is:
Consecutive statements on a line must be separated by ';'
If I hit the "Fix" button on the error message it inserts a ; right after "1.0" but I don't think this is right because the way I have it is how I see it in every online example. Plus it goes on to complain about '$' is not an identifier; use backticks to escape it. And fixing those causes more problems. Hopefully this makes sense to someone with more knowledge than me.

SearchIO.parse xml blast and ampersands cElementTree.ParseError: not well-formed (invalid token) error

I would like some advice to work around an xml parsing error. In my BLAST xml output, I have a description that has an '&' character which is throwing off the SearchIO.parse function.
If I run
qresults=SearchIO.parse(PLAST_output,"blast-xml")
for record in qresults:
#do some stuff
I get the following error:
cElementTree.ParseError: not well-formed (invalid token): line 13701986, column 30
Which directs me to the this line:
<Hit_def>Lysosomal & prostatic acid phosphatases [Xanthophyllomyces dendrorhous</Hit_def>
Is there a way to override this in biopython so I do not have to change my xml file? Right now, I'm just doing a 'Try/Except' loop, but that is not optimal!
Thanks for your help!

Read a list from stream using Yap-Prolog

I want to run a (python3) process from my (yap) prolog script and read its output formatted as a list of integers, e.g. [1,2,3,4,5,6].
This is what I do:
process_create(path(python3),
['my_script.py', MyParam],
[stdout(pipe(Out))]),
read(Out, OutputList),
close(Out).
However, it fails at read/2 predicate with the error:
PL_unify_term: PL_int64 not supported
Exception ignored in: <_io.TextIOWrapper name='<stdout>' mode='w' encoding='UTF-8'>
BrokenPipeError: [Errno 32] Broken pipe
I am sure that I can run the process correctly because with [stdout(std)] parameter given to process_create the program outputs [1,2,3,4,5,6] as expected.
Weird thing is that when I change the process to output some constant term (as constant_term) it still gives the same PL_int64 error. Appending a dot to the process' output ([1,2,3,4,5,6].) doesn't solve the error. Using read_term/3 gives the same error. read_string/3 is undefined in YAP-Prolog.
How can I solve this problem?

After asking at the yap-users mailing list I got the solution.
Re-compiled YAP Prolog 6.2.2 with libGMP option and now it works. It may also occur in 32-bit YAP.

Ruby on Rails jsonparse error

Already I have spent a lot time to resolve the issue but not getting the actual reason.
I have a issue during parsing the json, below is the my josn which i am trying to format.
ERROR: 757: unexpected token at '"{\"requestId\":\"2323423432\",\"bids\":\"[ {\\"adId\\":50000001, \\"bidNative\\":100,\\"clickPayload\\":\\"clickPayload-1\\", \\"impressionPayload\\":\\"236|458795|12345\\"}, {\\"adId\\":60000002, \\"bidNative\\":200,\\"clickPayload\\":\\"clickPayload-2\\", \\"impressionPayload\\":\\"236|458795|12345\\"}, {\\"adId\\":60000002, \\"bidNative\\":300,\\"clickPayload\\":\\"clickPayload-3\\", \\"impressionPayload\\":\\"236|458795|12345\\"}]\"}"'
actually wherever it shows 2 slashes there are actually 3, but i dont know why stack overflows editor shows like this.
