XML Parsing

[aeroswat]

So I've never worked with XML before and I want to use the google API's. I've been doing quite a bit of scouting and this is what I've seen two different ways of doing things for the most part but neither are working for me Here is the code i was using

$objDOM = new DOMDocument();
$objDOM->loadXML('http://www.google.com/ig/api?weather=New%20York');

$weather = $objDOM->getElementsByTagName("current_conditions");

foreach( $weather as $value )
{
	$dows = $value->getElementsByTagName("day_of_week");
	$dow = $dows->item(0)->nodeValue;

	$lows = $value->getElementsByTagName("low");
	$low = $lows->item(0)->nodeValue;

	$highs = $value->getElementsByTagName("highs");
	$high = $highs->item(0)->nodeValue;

	$conditions = $value->getElementsByTagName("condition");
	$condition = $conditions->item(0)->nodeValue;

	$pics = $value->getElementsByTagName("icon");
	$pic  = $pics->item(0)->nodeValue;

	echo "Day of Week: $dow <br>";
	echo "Low: $low <br>";
	echo "High: $high <br>";
	echo "Condition: $condition <br>";
	echo "<img src='www.google.com" . $pic . "' /><br /><br />"; 
} 

 

Can someone help me with what I'm doing wrong? It's not outputting anything but the labels

 

When I go to that address this is what prints out

 

<xml_api_reply version="1">

Umm, you can use simpleXML instead, easier.

Umm, you can use simpleXML instead, easier.

 

I found this example on SimpleXML

 

  $library = simplexml_load_file('library.xml');
  foreach ($library->shelf as $shelf) {
      printf("Shelf %s\n", $shelf['id']);
      foreach ($shelf->book as $book) {
          printf("Title: %s\n", $book->title);
          printf("Author: %s\n", $book->author);
      }
  } 

 

so can i place this string in the load file function or do I need to do something else to it before I use it in that function?

So I tried this...

 

	$forecast = simplexml_load_file('http://www.google.com/ig/api?weather=New%20York');
foreach ($forecast->forecast_conditions as $weather) {
	printf("Day of Week %s\n", $weather['day_of_week']);
} 	

 

And it didn't do anything. Any advice or direction would be appreciated.

[dezkit]

try foreaching

echo $weather->day_of_week["data"]; 

if doesnt work:

echo $weather["day_of_week"]["data"]; 

[aeroswat]

try foreaching

echo $weather->day_of_week["data"]; 

if doesnt work:

echo $weather["day_of_week"]["data"]; 

 

Tried both :/ Neither work

	<?php
$forecast = simplexml_load_file('http://www.google.com/ig/api?weather=New%20York');
foreach ($forecast->weather->forecast_conditions as $weather) {
	echo $weather->day_of_week["data"];
} 	
?>

lol

[aeroswat]

	<?php
$forecast = simplexml_load_file('http://www.google.com/ig/api?weather=New%20York');
foreach ($forecast->weather->forecast_conditions as $weather) {
	echo $weather->day_of_week["data"];
} 	
?>

lol

 

You are awesome! Thanks So I'm guessing anytime it has an encapsulating tag of its own it needs to be included in that foreach?

	<?php
$forecast = simplexml_load_file('http://www.google.com/ig/api?weather=New%20York');
foreach ($forecast->weather->forecast_conditions as $weather) {
	echo $weather->day_of_week["data"];
} 	
?>

lol

Yeah!! I thought you had included that thing lol, I thought it was a problem on php's side, but then I re read the xml.
