I am trying to read XML data in Arduino from a google spreadsheet published to the web using an HTTP GET request to the following link.
https://spreadsheets.google.com/feeds/cells/SpreadsheetID/5/public/basic?&range=D10
I receive the following reply along with some headers which I can observe on the serial port.
I want to parse the data written in bold format in the above reply. The data can be a real number and can be positive & negative. Please help me to find a way to parse this data.
if you need only one-two easy(out of param) nodes, you can use my function :)
String xmlTakeParam(String inStr,String needParam)
{
if(inStr.indexOf("<"+needParam+">")>0){
int CountChar=needParam.length();
int indexStart=inStr.indexOf("<"+needParam+">");
int indexStop= inStr.indexOf("</"+needParam+">");
return inStr.substring(indexStart+CountChar+2, indexStop);
}
return "not found";
}
I tried to find a solution for a long time, leave it here for clarity.
The complex xml with repeating nodes already so will not succeed.
Have you checked out this library?

You're better off converting your XML to JSON and giving that a go considering the memory availability on Arduino.
Otherwise if you really want to work with XML, then there's always these resources:

Scenario: I've been stuck on this for way to long and I think solution might be easy but I just can't see it, this is the scenario:
cURL POST to http://localhost:8080/my_imports (raw JSON data on body)
->
MyImportsCustomHandler (extends ThreadedHttpRequestHandler [Validations]
->
MyObjectProcessor (extends Processor) [JSON deserialize and data massage]
->
MyFirstDocumentProcessor (extends DocumentProcessor) [Set some fields and save]
Problem is that execution never reaches MyFirstDocumentProcessor, likely because request didn't started from the document_api endpoints (intentionaly).
There are no errors thrown, just processing route never reaches the document processor chain, I think it should because on MyObjectProcessor I'm doing:
DocumentType type =
localDocHandler.getDocumentTypeManager().getDocumentType("my_doc");
DocumentId id = new DocumentId("id:default:my_doc::2");
Document document = new Document(type, id);
DocumentPut docPut = new DocumentPut(document);
Processing proc = com.yahoo.docproc.Processing.of(docPut);
I got this idea from here: https://github.com/vespa-engine/vespa/blob/master/docproc/src/test/java/com/yahoo/docproc/util/SplitterJoinerTestCase.java
but on that test I see this line splitter.process(p);, which I'm not able to find a suitable replacement that works inside a Processor, in that context I only have the Request, Execution and DocumentProcessingHandler
I hope somebody versed on Vespa con shine some light on this, is just the last hop on the processing chain that I can't bridge :|
To write documents from Java code, you need to use the Document Access API:
http://docs.vespa.ai/documentation/document-api-guide.html#document-access
A working solution is in https://github.com/vespa-engine/sample-apps/pull/44
I am a Java developer and I have couple of questions related to Google speech API V1Beta1.
Question1 (Syncrecognize case):
I tried to upload (through GCS) small size (less than one min running file) audio file to google speech api it is working But the confidence output level is 0.32497215 only. That is my result is not exactly same to my audio input.
How to increase the confidence level output?
Question 2 (Asyncrecognize case):
I tried big size audio file (more than one min running file). This case I used the API call:
https://speech.googleapis.com/v1beta1/speech:asyncrecognize?key=XXXXXXXXXXXXXXXXXXXX
and Payload:
"{"config":{"encoding":"LINEAR16","sample_rate": 16000},"audio":{"uri":"gs://" + bucketName +"/"+ objectName + ""}}"
Here I got the output json like
{"name": "57...........................95"}.
After getting this output I make new API call (Operation interface) with this name value.
https://speech.googleapis.com/v1beta1/operations/57.................................95?key=XXXXXXXXXXXXXXXXX
I got the output
{
"name": "57....................................95",
"done": true,
"response": {
"#type": "type.googleapis.com/google.cloud.speech.v1beta1.AsyncRecognizeResponse"
}
}
How to proceed the work with this value? I need to get audio speech text.
Please help me to fix this issues. Thanks in advance.
Ideas to Question 1:
You should give more details in RecognitionConfig object, for example specify the languageCode and add hints via the SpeechContext object.
Answer to Question 2:
Check the sample rate of the audio file, you must be sure that is equal to the rate you gave in the request. You can check it e.g. with the following code soxi audio_file.flac (sox needed for this one).
I was able to use the Java API to decode the binary that is read from Kafka as there is BinaryDecoder from the DecoderFactory. I am trying repeat this using the C API.
However, no luck so far. It is straightforward to set values and then get values (schema and data are bond with each other). In the case where the encoded data is put into Kafka, we need to decode the data using a provided schema. Can you anyone shed some light on how to do this using the C API? Thanks a lot!
For example, we will get the following encoded data from Kafka
" site_visit^Z111.222.333.444^#^T1446231845^#^N1209600^#^F1.0"
and we have the schema available (separated from the data above, as we do using Java):
I want to the decoded data to be:
{"segment_name": "site_visit", "ip_address": "111.222.333.444", "received_at": "T1446231845", "ttl": "1209600", "probability": "1.0"}
You can use libserdes for this purpose. There are examples (serdes-kafka-avro-client.c, kafka-serdes-avro-console-consumer.cpp) how to get such JSON result.
I want to parse Swagger data from the JSON I get from {service}/swagger/docs/v1 into dynamically generated .NET class.
The problem I am facing is that different APIs can have different number of parameters and operations. How do I dynamically parse Swagger JSON data for different services?
My end result should be list of all APIs and it's operations in a variable on which I can perform search easily.
Did you ever find an answer for this? Today I wanted to do the same thing, so I used the AutoRest open source project from MSFT, https://github.com/Azure/autorest. While it looks like it's designed for generating client code (code to consume the API documented by your swagger document), at some point on the way producing this code it had to of done exactly what you asked in your question - parse the Swagger file and understand the operations, inputs and outputs the API supports.
In fact we can get at this information - AutoRest publically exposes this information.
So use nuget to install AutoRest. Then add a reference to AutoRest.core and AutoRest.Model.Swagger. So far I've just simply gone for:
using Microsoft.Rest.Generator;
using Microsoft.Rest.Generator.Utilities;
using System.IO;
...
var settings = new Settings();
settings.Modeler = "Swagger";
var mfs = new MemoryFileSystem();
mfs.WriteFile("AutoRest.json", File.ReadAllText("AutoRest.json"));
mfs.WriteFile("Swagger.json", File.ReadAllText("Swagger.json"));
settings.FileSystem = mfs;
var b = System.IO.File.Exists("AutoRest.json");
settings.Input = "Swagger.json";
Modeler modeler = Microsoft.Rest.Generator.Extensibility.ExtensionsLoader.GetModeler(settings);
Microsoft.Rest.Generator.ClientModel.ServiceClient serviceClient;
try
{
serviceClient = modeler.Build();
}
catch (Exception exception)
{
throw new Exception(String.Format("Something nasty hit the fan: {0}", exception.Message));
}
The swagger document you want to parse is called Swagger.json and is in your bin directory. The AutoRest.json file you can grab from their GitHub (https://github.com/Azure/autorest/tree/master/AutoRest/AutoRest.Core.Tests/Resource). I'm not 100% sure how it's used, but it seems it's needed to inform the tool about what is supports. Both JSON files need to be in your bin.
The serviceClient object is what you want. It will contain information about the methods, model types, method groups
Let me know if this works. You can try it with their resource files. I used their ExtensionLoaderTests for reference when I was playing around(https://github.com/Azure/autorest/blob/master/AutoRest/AutoRest.Core.Tests/ExtensionsLoaderTests.cs).
(Also thank you to the Denis, an author of AutoRest)
If still a question you can use Swagger Parser library:
https://github.com/swagger-api/swagger-parser
as simple as:
// parse a swagger description from the petstore and get the result
SwaggerParseResult result = new OpenAPIParser().readLocation("https://petstore3.swagger.io/api/v3/openapi.json", null, null);
I need to optimize the read/write count for a POST request that I'm using.
Some info about the request:
The user sends a JSON array of ~100 items
The servlet needs to check if any of the received items is newer then its counterpart in the datastore using a single long attribute
I'm using JDO
what i currently do is (pseudo code):
foreach(item : json.items) {
storedItem = persistenceManager.getObjectById(item.key);
if(item.long > storedItem.long) {
// Update storedItem
}
}
Which obviously results in ~100 read requests per request.
What is the best way to reduce the read count for this logic? Using JDO Query? I read that using "IN"-Queries simply results in multiple queries executed after another, so I don't think that would help me :(
There also is PersistenceManager.getObjectsById(Collection). Does that help in any way? Can't find any documentation of how many requests this will issue.
I think you can use below call to do a batch get:
Query q = pm.newQuery("select from " + Content.class.getName() + " where contentKey == :contentKeys");
Something like above query would return all objects you need.
And you can handle all the rest from here.
Best bet is
pm.getObjectsById(ids);
since that is intended for getting multiple objects in a call (particularly since you have the ids, hence keys). Certainly current code (2.0.1 and later) ought to do a single datastore call for getEntities(). See this issue
