i can't read and parse xml file in php-CodePudding

i have a xml file and I am trying to access the data in a xml file but it return an empty array.

Could the problem be in the file itself?

I have tried to use Basic SimpleXML usage this is my php code i used:

<?php
libxml_use_internal_errors(TRUE);

$xml = file_get_contents("https://egytech4uu.herokuapp.com/data.xml");

$XML = simplexml_load_string($xml, "SimpleXMLElement", LIBXML_NOCDATA);
$json = json_encode($XML);
$arr = json_decode($json,TRUE);
print_r($arr);

?>

CodePudding user response：

Here's one for you:

<?php
$xmldata = file_get_contents("https://egytech4uu.herokuapp.com/data.xml");
$xmlparser = xml_parser_create();
$arr = [];
xml_parse_into_struct($xmlparser, $xmldata, $arr);
xml_parser_free($xmlparser);
print_r($arr);

So what's going there? It returns a flat array, but for each node at least we can see its level. A random item in this array might look like this:

    {
        "tag": "XS:ELEMENT",
        "type": "complete",
        "level": 9,
        "attributes": {
            "NAME": "ARABIC_NAME",
            "TYPE": "xs:string",
            "MINOCCURS": "0"
        }
    },

You are looking to loop the <Ticker> tags.

<Ticker diffgr:id="Ticker209" msdata:rowOrder="208">
    <SYMBOL>AMPI.CA</SYMBOL>
    <ARABIC_NAME>المؤشر للبرمجيات ونشر المعلومات</ARABIC_NAME>
    <CLOSE>2.37</CLOSE>
    <OPEN>2.37</OPEN>
    <ENGLISH_NAME>Al Moasher for Programming and Information Dissemination</ENGLISH_NAME>
</Ticker>

It's equivalent array nodes are (remember this is flat array):

 {
        "tag": "TICKER",
        "type": "open",
        "level": 4,
        "attributes": {
            "DIFFGR:ID": "Ticker209",
            "MSDATA:ROWORDER": "208"
        },
        "value": "\n        "
    },
    {
        "tag": "SYMBOL",
        "type": "complete",
        "level": 5,
        "value": "AMPI.CA"
    },
    {
        "tag": "TICKER",
        "value": "\n        ",
        "type": "cdata",
        "level": 4
    },
    {
        "tag": "ARABIC_NAME",
        "type": "complete",
        "level": 5,
        "value": "المؤشر للبرمجيات ونشر المعلومات"
    },
    {
        "tag": "TICKER",
        "value": "\n        ",
        "type": "cdata",
        "level": 4
    },
    {
        "tag": "CLOSE",
        "type": "complete",
        "level": 5,
        "value": "2.37"
    },
    {
        "tag": "TICKER",
        "value": "\n        ",
        "type": "cdata",
        "level": 4
    },
    {
        "tag": "OPEN",
        "type": "complete",
        "level": 5,
        "value": "2.37"
    },
    {
        "tag": "TICKER",
        "value": "\n        ",
        "type": "cdata",
        "level": 4
    },
    {
        "tag": "ENGLISH_NAME",
        "type": "complete",
        "level": 5,
        "value": "Al Moasher for Programming and Information Dissemination"
    },
    {
        "tag": "TICKER",
        "value": "\n      ",
        "type": "cdata",
        "level": 4
    },
    {
        "tag": "TICKER",
        "type": "close",
        "level": 4
    },
    {
        "tag": "TICKER",
        "value": "\n      ",
        "type": "cdata",
        "level": 3
    },

So there's some work to do here, but I think all the data is there.
