KML file rendering issue - smooth text - kml
We have KML files that have some very tightly-defined polylines in them (used to draw text mostly, but not solely). When we pull in the same KML file into Cesium (1.6 or 1.7), or OpenLayers, or GoogleEarth, I get the same results:
Cesium renders the text in a very jagged manner.
OpenLayers & GoogleEarth both render the text smoothly.
We’ve looked at the removeDuplicates() methods that we think are responsible for the “thinning” of data. If we set the EPSILON to be a higher value, the “text polylines” are rendered nicely. Can we override the removeDuplicatesEpsilon variable somewhere?
Inside the removeDuplicates() method, once it’s determined that we have at least 1 point to remove, it looks like compares each subsequent point to the previous point in the list. Shouldn’t it compare each point to the previously-accepted point? (as opposed to just the previous point in the list, which may not be included either).
Cesium code:
var removeDuplicatesEpsilon = CesiumMath.EPSILON7;
PolylinePipeline.removeDuplicates = function(positions) {
if (!defined(positions)) {
throw new DeveloperError('positions is required.');
}
var length = positions.length;
if (length < 2) {
return undefined;
}
var i;
var v0;
var v1;
for (i = 1; i < length; ++i) {
v0 = positions[i - 1];
v1 = positions[i];
if (Cartesian3.equalsEpsilon(v0, v1, removeDuplicatesEpsilon)) {
break;
}
}
if (i === length) {
return undefined;
}
var cleanedPositions = positions.slice(0, i);
for (; i < length; ++i) {
v0 = positions[i - 1];
v1 = positions[i];
if (!Cartesian3.equalsEpsilon(v0, v1, removeDuplicatesEpsilon)) {
cleanedPositions.push(Cartesian3.clone(v1));
}
}
return cleanedPositions;
};

This does appear to be a bug in Cesium. I've opened pull request #2609 to fix it.

Why does this .kml file load at latitude zero/longitude zero?
I created this .kml file by hand, outlining an area in New Hampshire, US. It loads fine in Google MyMaps, but if I load it in Google Earth, it apparently gets placed at "Null Island" (latitude 0, longitude 0).

How to modify and XML on the fly?
I am reading a XML file and send it to a REST API. However before sending it I would like to modify some values.
This is how I send the data:
data = await readFile(path.resolve(__dirname, file), 'utf8');
const config = {
headers: {
'Content-Type': 'text/plain',
'Content-Length': data.length,
},
};
result = await axios.post(
'https://someRestapi.com/',
data, config,
);
And I want to change the name Simon to Zimon in the author name for example.
<?xml version="1.0" encoding="UTF-8"?>
<Document schemaVersion="12"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Author>
<Name>
<First>Simon</First>
<Second>SomeName</Second>
</Name>
</Author>
</Document>
Is there an easy solution to do this?
Had to do something similar recently and ended up using fast-xml-parser. Applied to your case, you could do:
const xmlString = `<?xml version="1.0" encoding="UTF-8"?>
<Document schemaVersion="12"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Author>
<Name>
<First>Simon</First>
<Second>SomeName</Second>
</Name>
</Author>
</Document>`;
const xmlToJsonParser = require('fast-xml-parser');
const J2xParser = require("fast-xml-parser").j2xParser;
const tObj = xmlToJsonParser.getTraversalObj(xmlString,{ignoreAttributes :false});
const jsonObj = xmlToJsonParser.convertToJson(tObj,{ignoreAttributes :false});
jsonObj.Document.Author.Name.First = "Zimon";
let result = new J2xParser({format:true, ignoreAttributes :false}).parse(jsonObj);
result = `<?xml version="1.0" encoding="UTF-8"?>\n${result}`;
console.log(result);
This will print:
<?xml version="1.0" encoding="UTF-8"?>
<Document schemaVersion="12" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Author>
<Name>
<First>Zimon</First>
<Second>SomeName</Second>
</Name>
</Author>

Groovy question to read xml and base64decode
I want to modify the incoming message (As shown in the Modified XML) output.
Incoming XML
<xml>
<Body>
<Request>
<Container>
<name>test</name>
<Numbers>
<sn>//base64encodedstring//</sn>
<sn>//base64encodedstring//</sn>
<sn>//base64encodedstring//</sn>
</Numbers>
</Container>
</Request>
</Body>
</xml>
Modified XML
<xml>
<Body>
<Request>
<Container>
<name>test</name>
<Numbers>
<sn>//Decodedstring//</sn>
<sn>//Decodedstring//</sn>
<sn>//Decodedstring//</sn>
</Numbers>
</Container>
</Request>
</Body>
</xml>
As per the answer received: I can create an array of ListOfResults.
def listOfResults = new XmlSlurper()
.parseText(xml)
.Body.Request.Container.Numbers.sn
.collect { new String(it.text().decodeBase64()) }
I can do the following
def data = "<xml><Body><Request><Container><name>test</name><Numbers>"
for (i= 0; i <listOfResults.size(); i++)
{
data = data +"<sn>" +listOfResults[i] + "</sn>";
}
data = data + "<Numbers></Container></Request></Body></xml>";
Modified data
<xml><Body><Request><Container><name>test</name>
<Numbers>
<sn>decoded string</sn>
<sn>decoded string</sn>
<sn>decoded string</sn>
</Numbers> </Container></Request></Body></xml>
Is this the fastest way to do this operation? Is there any other better way?
You should be able to do (assuming your XML is in a string variable called xml):
def listOfResults = new XmlSlurper()
.parseText(xml)
.Body.Request.Container.Numbers.sn
.collect { new String(it.text().decodeBase64()) }
Cannot parse kml file to be treated as xml
I want to parse a kml file to be treated like a xml file :
var parser = require('xml2json');
router.get('/', function (req, res) {
var xml = "D:/Axes2019.kml";
var json = parser.toJson(xml);
console.log("to json -> %s", json);
res.render("index");
});
At runtime I get There are errors in your xml file: not well-formed (invalid token)
Here is the kml :

So how to fix it ?
I checked your sample KML for XML and KML Schema validity, and it looked fine to me. Maybe your parser wants more of the namespaces defined? See below for what I usually include at the top of my KMLs: <?xml version="1.0" encoding="UTF-8"?> <kml xmlns="http://www.opengis.net/kml/2.2" xmlns:gx="http://www.google.com/kml/ext/2.2" xmlns:kml="http://www.opengis.net/kml/2.2" xmlns:atom="http://www.w3.org/2005/Atom"> ... </kml> Or maybe some of the rest of your file (which you replaced with "..." contains XML errors? Make sure all your IDs are valid too (start with a letter, no forbidden characters, etc.).
Setup a clearkey server for shaka player didn't work?
I've created a test html page for playing a MPEG-CENC protected MPEG-DASH video, and I can play if I specify kid: key pair in player.configure().
Then I want to setup a clearkey server. Refer to DRM Configuration section of Shaka Player documents, I changed the code to specify the url to get the license like below. But the page never get touched when I set a breakpoint in Page_Load event in Visual Studio. There is no error on console of browser.
The browser I use is Firefox 53.0.2 and Chrome 58.0.3029.96. Did I miss something?
