I am getting a SimpleXML object back from a server using Guzzle. The response printed as string looks like valid XML. But when I try to get the individual element values, I am getting blank.
Please help me find what the problem is.
My code is here as well as on Viper-7:

$sXml = simplexml_load_string ($xml);

print_r($order);
echo "<br/>";
}
?>
Note: By putting your code into your question, you will make it easier for others to help you.
$xml = simplexml_load_string($x); // assume XML in $x
You will need 2 nested loops to iterate. First, you will want to select the <OrdersList>-nodes correctly, see the outer loop.
foreach ($xml->OrdersList as $orders) {
The children of <OrdersList> are namespaced:
$order->OrderNumber doesn't work, but the children()-method does the job:
foreach ($orders->children("typ", TRUE) as $name => $value) {
echo "$name: $value <br />";
}
}

I am a beginner on PHP and XML.
I have a XML file as below (partly):
<combination>
<id_combination>2289</id_combination>
<quantity>4</quantity>
<unit_price_impact>0.000000</unit_price_impact>
<reference>K10100.1B</reference>
<group_name>Color</group_name>
<attribute_name>Blue</attribute_name>
</combination>
<combination>
<id_combination>2289</id_combination>
<quantity>4</quantity>
<unit_price_impact>0.000000</unit_price_impact>
<reference>K10100.1B</reference>
<group_name>Size</group_name>
<attribute_name>1</attribute_name>
</combination>
<combination>
<id_combination>2290</id_combination>
<quantity>20</quantity>
<unit_price_impact>0.000000</unit_price_impact>
<reference>K10100.2B</reference>
<group_name>Color</group_name>
<attribute_name>Blue</attribute_name>
</combination>
<combination>
<id_combination>2290</id_combination>
<quantity>20</quantity>
<unit_price_impact>0.000000</unit_price_impact>
<reference>K10100.2B</reference>
<group_name>Size</group_name>
<attribute_name>2</attribute_name>
</combination>
And i desire to get an array as described below:
$id_combination => 2289
$reference => K10100.1B
$combination_name => Color: Blue / Size: 1
$quantity => 4
$id_combination => 2290
$reference => K10100.2B
$combination_name => Color: Blue / Size: 2
$quantity => 20
I want to join data with the same 'id_combination' nodes and then process it in PHP.
I tried to use "foreach" loop, "array_unique", "implode" and etc.. but wasn't able to get any success.
I would appreciate anyone would help me straight to result with the suggested code.
i just did the following changes to your xml and have append new code and look and worked on my xampp server

Consider an XSLT solution as this is a typical need for the Muenchian Method in XSLT 1.0 used to group nodes by various keys. As information, XSLT is a special-purpose language designed to transform XML files and like most general purpose languages, PHP maintains an XSLT processor.
XSLT Script (save as .xsl to be loaded in script below)
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output version="1.0" encoding="UTF-8" indent="yes" />
<xsl:strip-space elements="*"/>
<xsl:key name="idkey" match="combination" use="id_combination" />
<xsl:template match="combinations">
<xsl:copy>
<xsl:apply-templates select="combination[generate-id() =
generate-id(key('idkey',id_combination)[1])]"/>
</xsl:copy>
</xsl:template>
<xsl:template match="combination[generate-id() =
generate-id(key('idkey',id_combination)[1])]">
<xsl:copy>
<xsl:copy-of select="id_combination|quantity|unit_price_impact|reference"/>
<combination_name>
<xsl:for-each select="key('idkey',id_combination)">
<xsl:value-of select="concat(group_name, ': ', attribute_name)" />
<xsl:if test="position() != last()">
<xsl:text> / </xsl:text>
</xsl:if>
</xsl:for-each>
</combination_name>
</xsl:copy>
</xsl:template>
</xsl:transform>
PHP Script
// LOAD XML AND XSL FILES
$xml = new DOMDocument('1.0', 'UTF-8');
$xml->load('Input.xml');
$xslfile = new DOMDocument('1.0', 'UTF-8');
$xslfile->load('XSLTScript.xsl');
// TRANSFORM XML with XSLT
$proc = new XSLTProcessor;
$proc->importStyleSheet($xslfile);
$newXml = $proc->transformToXML($xml);
// ECHO OUTPUT STRING
echo $newXml;
$xml = new SimpleXMLElement($newXml);
$xpath = $xml->xpath('//combination');
$array = [];
foreach($xpath as $result){
$inner = [];
foreach ($result as $node => $item) {
$inner[$node] = (string)$item;
}
$array[] = $inner;
}
var_dump($array);

Below is my xml with namespace

i trying below php code (xpath) using foreach to get values of the ratenode
$xd = simplexml_load_file('C:/inetpub/vhosts/test.com/data_download/q.xml');
$xd->registerXPathNamespace("n", "http://www.test.com/schemas/messages");
foreach($xd->xpath("//n:hotels/n:hotel") as $xd_item)
{
echo 'item - A';
foreach($xd_item->xpath("rooms/room") as $xd_room)
{
foreach($xd_room->xpath("rates/rate") as $xd_rate)
{
echo 'rate - C';
}
}
}
In the foreach of $xd_item is not working. I mean the 2nd foreach its end with the value "echo 'item - A';" anyone can help me?
The problem with your codes is, as mentioned by #kjhughes in his comment, that some elements are in the default namespace but your XPath missed to use the corresponding prefix on those elements. Also, your code prints static literal strings i.e 'item - A' and 'rate - C', not any part of the XML being parsed.
" Is possible to write conditions like $xd->xpath("rates/rate[#id='1']") in dom"
Yes it is possible. It is also possible using SimpleXML, for example :
$xd->registerXPathNamespace("n", "http://www.test.com/schemas/messages");
foreach($xd->xpath("//n:rate[#id='1']") as $rate){
echo $rate["id"] .", ". $rate["adults"] .", ". $rate["child"] ."\r\n";
}
eval.in demo
output :
//id, adults, rate
1, 1, 0
The variable $xd_item is of type SimpleXMLElement from which you can access its room properties like this for example:
$xd_item->rooms->room
This will return an object of type SimpleXMLElement from which you can get the rates and you can loop using a foreach. The values that you want from the 'rate' are in the attributes
For example:
$xd = simplexml_load_file('C:/inetpub/vhosts/test.com/data_download/q.xml');
$xd->registerXPathNamespace("n", "http://www.test.com/schemas/messages");
foreach($xd->xpath("//n:hotels/n:hotel") as $xd_item)
{
foreach($xd_item->rooms->room as $room) {
foreach ($room->rates->rate as $rate) {
echo sprintf(
'id: %s<br>adults: %s<br>child: %s<br><br>',
$rate->attributes()->id->__toString(),
$rate->attributes()->adults->__toString(),
$rate->attributes()->child->__toString()
);
}
}
}
I need something to either replace the colon, or find a way to work with it. This tag is inside of multiple other tags. This XML that is the problem:
<ns2:Amount>9.99</ns2:Amount>

I need to have amount = 9.99 in PHP.
Try this with basic PHP:
$subject = "<ns2:Amount>9.99</ns2:Amount>
<ns2:Test>ABCD</ns2:Test>"; // suppose you have two tags
preg_match_all('/<[^:]*:([^>]*)>(.*)<\/[^>]*>/', $subject, $matches); // matching
$i = 1;
$ii = 0;
foreach ($matches as $key => $value) {
$newArr[$matches[$i][$ii]] = $matches[$ii][$ii];
$ii++;
$i++;
}
$result = array_filter($newArr);
foreach($result as $key => $value){
echo $key." = ".$value. "<br/>";
}
Result is:
Amount = 9.99
Test = ABCD
I was able to create a code that let me ignore the namespaces. This is what it looks like.
$Amount = $xml->GetMatchingProductForIdResult[0]->Products->Product->AttributeSets->children('ns2', true)->ItemAttributes->Binding->Amount;
I am using this script to find out daily visitor and total pageview for the day.

This file is saved somewhere in the server.
Using this code for fetching
$xml = simplexml_load_file("PATH To FILE", null, null, 'aws', true);
$pageview=$income_data->Response->UrlInfoResult->Alexa->TrafficData->UsageStatistics->UsageStatistic->PageViews->PerMillion->Value;
$daily_pageview=$pageview*10;
Everything is fine until i found that the results were not right for few domain values. Then i tried to echo each of the value and i found out that it is ignoring values after point(.)
[Like for example]
.02=>0
.100=>0
1.02=>1
In above case value of $pageview=0.21 and output is 0 but it is supposed to come 2.1.
Any help with this would be appreciated ..
I would guess it's the way the value is being casted from a SimpleXMLElement, at least that's what the below points to.
<?php
$xml = '
<testdata>
<foo>1.2</foo>
</testdata>
';
$xml = new SimpleXMLElement($xml);
echo get_class($xml->foo); //SimpleXMLElement
echo 1.2 * 2; // 2.4
echo $xml->foo * 2; // 2
echo (float)$xml->foo * 2; // 2.4

I know how to open and close/save file using PHP, I don't know how to delete the part i don't want... If anyone would help me with that I would be extremly thankfull!
You can either use SimpleXML, DOM or XSL for it.
Example XML (shortened for brevity (from Revision 1 of your question)):
$xml = <<< XML
<CriminalCase>
<Charge>
<DispositionDate>1995-12-21</DispositionDate>
</Charge>
<Charge>
<DispositionDate>2010-12-21</DispositionDate>
</Charge>
</CriminalCase>
XML;
With SimpleXml
$sevenYearsAgo = new DateTime('-7 years');
$CriminalCase = new SimpleXmlElement($xml);
for ($i = 0; $i < $CriminalCase->Charge->count(); $i++) {
$dispositionDate = new DateTime($CriminalCase->Charge->DispositionDate);
if ($dispositionDate < $sevenYearsAgo) {
unset($CriminalCase->Charge[$i]);
}
}
echo $CriminalCase->asXml();
With DOM
$dom = new DOMDocument;
$dom->loadXml($xml);
$xpath = new DOMXPath($dom);
$oldCases = $xpath->query(
sprintf(
'//Charge[substring-before(DispositionDate, "-") < %d]',
date('Y', strtotime('-7 years'))
)
);
foreach ($oldCases as $oldCase) {
$oldCase->parentNode->removeChild($oldCase);
}
echo $dom->saveXml();
With XSLT
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:date="http://exslt.org/dates-and-times"
extension-element-prefixes="date">
<xsl:output indent="yes" method="xml"/>
<xsl:template match="/">
<CriminalCase>
<xsl:apply-templates />
</CriminalCase>
</xsl:template>
<xsl:template match="Charge">
<xsl:if test="date:year(DispositionDate) > date:year() - 7">
<xsl:copy-of select="."/>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
and then use this PHP Code to transform it
$doc = new DOMDocument();
$xsl = new XSLTProcessor();
$doc->loadXml($xsl);
$xsl->importStyleSheet($doc);
$doc->loadXml($xml);
echo $xsl->transformToXML($doc);
Here are some tips on how to get started:
You need to parse the XML to something a little easier to work with. PHP has a library called SimpleXML.
Loop through the data and remove the objects which are older than 7 years. To compare dates you have to first convert the dates you got from the XML to something PHP can process as a date. Take a look at strtotime which gives you the timestamp (seconds since 1970, actually 1901 for version > 5.1.0) or DateTime which supports dates before 1970.
To check if the fetched date is older than 7 years ago, you need to (one way) subtract the timestamp with the current timestamp, and see if that value is greater than 7 years in seconds. Or if you use DateTime, you can take a look at DateTime::diff. Remove the objects that you iterate over that are older than 7 years (unset).
To save as XML again, take a look at SimpleXMLElement::asXML
Hope that helps!
