Parse value from html-text web page - homeyscript

Questions & Help
#1

Hi

i have some homey script’s running to work with some json api’s, thats ok.

but now i am attempting to retireve a value from a plane html/txt web page
i need to get the: motionDetectAlarm value

if there is a flowcard that can do the job i can use that instead

<CGI_Result>
    <result>0</result>
    <IOAlarm>0</IOAlarm>
    <motionDetectAlarm>1</motionDetectAlarm>
    <humanDetectAlarmState>0</humanDetectAlarmState>
    <soundAlarm>0</soundAlarm>
    <record>0</record>
    <sdState>1</sdState>
    <sdFreeSpace>120847040k</sdFreeSpace>
    <sdTotalSpace>121739200k</sdTotalSpace>
    <ntpState>0</ntpState>
    <isWifiConnected>1</isWifiConnected>
    <wifiConnectedAP>wifi</wifiConnectedAP>
    <infraLedState>0</infraLedState>
</CGI_Result>

I found an online script, and fiddled with JSON.stringify() and slice() to filter on motionDetectAlarm
Further below is an Aflow homeyscript-card example

const xmlString = '<CGI_Result><result>0</result><IOAlarm>0</IOAlarm><motionDetectAlarm>1</motionDetectAlarm><humanDetectAlarmState>0</humanDetectAlarmState><soundAlarm>0</soundAlarm><record>0</record><sdState>1</sdState><sdFreeSpace>120847040k</sdFreeSpace><sdTotalSpace>121739200k</sdTotalSpace><ntpState>0</ntpState><isWifiConnected>1</isWifiConnected><wifiConnectedAP>wifi</wifiConnectedAP><infraLedState>0</infraLedState></CGI_Result>'; //provided xml

function convertXmlToJson(xmlString) {
    const jsonData = {};
    for (const result of xmlString.matchAll(/(?:<(\w*)(?:\s[^>]*)*>)((?:(?!<\1).)*)(?:<\/\1>)|<(\w*)(?:\s*)*\/>/gm)) {
        const key = result[1] || result[3];
        const value = result[2] && convertXmlToJson(result[2]); //recusrion
        jsonData[key] = ((value && Object.keys(value).length) ? value : result[2]) || null;
    }
    return jsonData;
}
var motionDetectAlarmState
motionDetectAlarmState = JSON.stringify(convertXmlToJson(xmlString)).slice(42,65);

console.log(`{${motionDetectAlarmState}}`);
return(true);

.
Output:

I used “Run code with argument and return text-tag”
Then the argument is the XML code
And the script:

// xml-2-json
const xmlString = args[0]; //provided xml

function convertXmlToJson(xmlString) {
    const jsonData = {};
    for (const result of xmlString.matchAll(/(?:<(\w*)(?:\s[^>]*)*>)((?:(?!<\1).)*)(?:<\/\1>)|<(\w*)(?:\s*)*\/>/gm)) {
        const key = result[1] || result[3];
        const value = result[2] && convertXmlToJson(result[2]); //recusrion
        jsonData[key] = ((value && Object.keys(value).length) ? value : result[2]) || null;
    }
    return jsonData;
}
var motionDetectAlarmState
motionDetectAlarmState = JSON.stringify(convertXmlToJson(xmlString)).slice(42,65);

console.log(`{${motionDetectAlarmState}}`);
return(`{${String(motionDetectAlarmState)}}`);
