How can I modify a SVG file by using XSLT?
I like to modify the following SVG (cutout) file:
<svg width="834px" height="707.5px" version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" overflow="visible">

I want to change the color for the symbol id="E050". To achieve this I tried to add the attribute fill="#ff0000" to the symbol definition.
This is the current version of my XSL file:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:svg="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns="http://www.w3.org/2000/svg">
<xsl:template match="node() | #*">
<xsl:copy>
<xsl:apply-templates select="node() | #*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="//symbol[#id='E050']">
<xsl:copy>
<xsl:apply-templates select="#*"/>
<xsl:attribute name="fill">#ff0000</xsl:attribute>
<xsl:apply-templates select="node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
How can I modify the XSL file that the color for the symbol id="E050 is changed but the rest is not modified?
To test the modification I'm using the online tool https://www.w3schools.com/xml/tryxslt.asp?xmlfile=cdcatalog&xsltfile=cdcatalog_ex1.
Change this line...
<xsl:template match="//symbol[#id='E050']">
To this line....
<xsl:template match="svg:symbol[#id='E050']">
(Note the // prefix is not necessary in a template match)
Although you have a default namespace declaration in your XSLT (xmlns="http://www.w3.org/2000/svg") this only applies to unprefixed elements in your XSLT (which also happens to be an XML document), not Xpath expressions in attributes. This doing a match on symbol[#id='E050'] is trying to match a symbol element in no namespace.
Alternatively, if you could use XSLT 2.0, you could add this line to the xsl:stylesheet element, as this would then mean unprefixed element names in xpath expressions would be given a namespace
xpath-default-namespace="http://www.w3.org/2000/svg"

I have a sequence of strings that look like this:
B5 C10 C8 D11 D13 D3 D7 D9 E12 E8
I did the <xsl:perform-sort and <xsl:sort, based on the default data-type="text" and it's working correctly. But I would like to further sort so that after the letter the values are sorted numerically:
B5 C8 C10 D3 D7 D9 D11 D13 E8 E12
Any suggestions on how to do that? Thanks!
Edited to add my code:
<xsl:variable name="pns1" as="xs:string*">
<xsl:perform-sort select="distinct-values($combo1/*:pin/*:pkg[$pos]/*:pn/#n)">
<xsl:sort select="."/>
</xsl:perform-sort>
</xsl:variable>
<xsl:variable name="pns2" as="xs:string*">
<xsl:perform-sort select="$pns1">
<xsl:sort select="." data-type="number"/>
</xsl:perform-sort>
</xsl:variable>
<xsl:message select="$pns2"/>
Saxon allows you a parameter alphanumeric="yes" on a collation URI, see https://www.saxonica.com/html/documentation11/localization/unicode-collation-algorithm/ so e.g.
'B5 C10 C8 D11 D13 D3 D7 D9 E12 E8'
=> tokenize('\s+')
=> sort('http://www.w3.org/2013/collation/UCA?alphanumeric=yes')
gives
B5 C8 C10 D3 D7 D9 D11 D13 E8 E12
.
Online fiddle with Saxon XQuery (but XPath/XSLT support it the same): https://xqueryfiddle.liberty-development.net/jyH9Xvk.
Using numeric=yes;fallback=yes might even give better compatibility between the various Saxon editions (HE, PE, EE) and platforms (Java, .NET):
'B5 C10 C8 D11 D13 D3 D7 D9 E12 E8'
=> tokenize('\s+')
=> sort('http://www.w3.org/2013/collation/UCA?numeric=yes;fallback=yes')
or even SaxonJS.
Consider the following example:
XSLT 2.0
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:variable name="strings" select="('D13', 'B5', 'C10', 'E12', 'C8', 'D11', 'D3', 'E8', 'D7', 'D9')" />
<xsl:template match="/">
<result>
<xsl:perform-sort select="$strings">
<xsl:sort select="substring(., 1, 1)"/>
<xsl:sort select="substring(., 2)" data-type="number"/>
</xsl:perform-sort>
</result>
</xsl:template>
</xsl:stylesheet>
Result
<?xml version="1.0" encoding="UTF-8"?>
<result>B5 C8 C10 D3 D7 D9 D11 D13 E8 E12</result>
I am currently trying to vectorize a modulo calculation using AVX512.
Because there is no AVX modulo operation (except SVML) or an integer division, I am using the following formula d % p = d - int(float(d)/float(p))*p.
However, for very large inputs, I get negative results.
#include <bits/stdc++.h>
#include <immintrin.h>
int main() {
const auto SIZE = 1024;
int64_t input[SIZE];
int64_t output[SIZE] = {};
const auto p = 1'536; // 1.5 * 1024
std::iota(input, input + SIZE, 15596705878733779060ULL);
__m512i _divider_512 = _mm512_set1_epi64(p);
for (size_t idx = 0; idx < SIZE; idx += 8) {
__m512i _inputs = _mm512_loadu_si512(&input[idx]);
__m512i _e = _mm512_cvt_roundpd_epi64(_mm512_div_pd(_mm512_cvtepi64_pd(_inputs), _mm512_cvtepi64_pd(_divider_512)), _MM_FROUND_TO_NEG_INF | _MM_FROUND_NO_EXC);
__m512i _mult = _mm512_mullo_epi64(_e, _divider_512);
__m512i _modulo_result = _mm512_sub_epi64(_inputs, _mult);
_mm512_storeu_si512(&output[idx], _modulo_result);
}
for (auto i = 0; i< SIZE; ++i) {
std::cout << output[i] << std::endl;
}
}

Is this a rounding error between ints and doubles? Or am I missing something else?
And how could I workaround it?
I have a sample dataset named Flights.I want to Extract from it the Origin
Airport name which has least number of departure delays.
Sample Flights data:-
Date (Sched_dep_time) (dep_time)(flight)(origin) (Dep_delay_min)
01-01-2013 5:15 5:17 1545 EWR -2
01-01-2013 5:29 5:33 1714 LGA -4
01-01-2013 5:40 5:42 1141 JFK -2
01-01-2013 21:10 21:04 725 JFK 6
01-01-2013 20:30 21:04 461 LGA -74
01-01-2013 21:06 21:05 1696 EWR 1
01-01-2013 20:55 21:10 507 EWR -55
01-01-2013 20:25 21:14 5708 LGA -89
01-01-2013 21:10 21:15 79 JFK -5
01-01-2013 21:24 21:16 301 LGA 8
01-01-2013 6:00 5:58 49 JFK 42
01-01-2013 6:00 5:58 71 JFK 42
01-01-2013 6:00 5:58 194 JFK 42
Code i Tried: -
Proc sql;
Create table least_delay as
Select origin,min(number_of_delays)as min_delay from
(Select Origin,Count(Departure_delay_minutes) as Number_of_delays from
Flight
Where (Departure_delay_minutes>0))
Group by Origin
;
Quit;
The output i get is following: -
Origin min_delay
1 NLI 1135504
2 JFK 1135504
3 LGA 1135504
It shows same result for all the origin!
Can anybody help me on this?
The specific problem in your code is that you need to add a group by Origin clause in the sub query. However, all this would do is return the number of delays for each Origin, not the Origin(s) with the least delay. A small change to the code, adding a having clause, fixes this.
data flight;
input Date :ddmmyy10. (Sched_dep_time dep_time) (:time.) flight origin $ Dep_delay_min;
format date date9. Sched_dep_time dep_time time. ;
datalines;
01-01-2013 5:15 5:17 1545 EWR -2
01-01-2013 5:29 5:33 1714 LGA -4
01-01-2013 5:40 5:42 1141 JFK -2
01-01-2013 21:10 21:04 725 JFK 6
01-01-2013 20:30 21:04 461 LGA -74
01-01-2013 21:06 21:05 1696 EWR 1
01-01-2013 20:55 21:10 507 EWR -55
01-01-2013 20:25 21:14 5708 LGA -89
01-01-2013 21:10 21:15 79 JFK -5
01-01-2013 21:24 21:16 301 LGA 8
01-01-2013 6:00 5:58 49 JFK 42
01-01-2013 6:00 5:58 71 JFK 42
01-01-2013 6:00 5:58 194 JFK 42
;
run;
proc sql;
create table least_delay
as select *
from (
select
origin,
count(0) as num_delays
from
flight
where
dep_delay_min>0
group by
origin
)
having num_delays = min(num_delays);
quit;
So I have the following code :
int main()
{
int b=0;
for(char c=0;c<256;c++)
b++;
cout<<b;
return 0;
}
Why does it run indefinitely? (I tried c<255 - because I thought of char like a circle:once it reaches 360 degrees, it goes back from 0 and c<255 should break this loop - it turned out it still ran indefinitely)
Why does it run indefinitely?
Irrespective of whether char is signed type or unsigned type, it will not reach the value of 256 if char is represented by 8 bits, which is the most common representation. It will always be less than 256.
Why don't you run the code and print value to understand how char c in your code is getting incremented?
int b=0;
for(char c=0;c<256;c++)
{
cout<<(int)c<<" ";
b++;
if(b == 256)break;
}
This code snippet outputs the following.
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127
-128 -127 -126 -125 -124 -123 -122 -121 -120 -119 -118 -117 -116 -115 -114 -113
-112 -111 -110 -109 -108 -107 -106 -105 -104 -103 -102 -101 -100 -99 -98 -97 -96
-95 -94 -93 -92 -91 -90 -89 -88 -87 -86 -85 -84 -83 -82 -81 -80 -79 -78 -77 -76
-75 -74 -73 -72 -71 -70 -69 -68 -67 -66 -65 -64 -63 -62 -61 -60 -59 -58 -57 -56
-55 -54 -53 -52 -51 -50 -49 -48 -47 -46 -45 -44 -43 -42 -41 -40 -39 -38 -37 -36
-35 -34 -33 -32 -31 -30 -29 -28 -27 -26 -25 -24 -23 -22 -21 -20 -19 -18 -17 -16
-15 -14 -13 -12 -11 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1
So, char never gets to 256. It gets to 127, and then when you try to increment it again, it wraps to -128.
Remember, typically char is represented by 8 bits and for signed char, the range is -128 to 127 and for unsigned char, the range is 0 to 255.
That's why, the condition c < 256 always evaluates to true and your code runs indefinitely.

Please help me. What's wrong with my code? Or how to fix that? I ready to disable any user-controls, css, images and ect. Advise me how to make it work
I know the answer! To fix this problem, enable autoload images!
