How to get 2 child ID value from XML? - php

I wanted to try to pick up Volume value from the Level1Data node.
Here is the xml:
<Response>
<Content>
<Level1Data Tick="U" Currency="USD" TickSize="0.0001000000" TickValue="0" AssetClass="Equity" InstrumentState="Open" LastPrice="24.1550" LotSize="10"
MinPermittedPrice="0" MaxPermittedPrice="0" ClosePrice="24.0300" OpenPrice="24.1500" FirstPrice="24.1500"
HighPrice="24.7800" LowPrice="24.0000" MaxPrice="24.7800" MinPrice="24.0000" Volume="16238302"
AskSize="105597" BidSize="97618" AskPrice="24.1600" BidPrice="24.1500" Symbol="BAC.NY"
MarketTime="12:08:41.356" Message="L1DB"/>
</Content>
</Response>
And then my main script:
<?php
$result = file_get_contents("lvl1.xml");
// echo $result;
$xml = new SimpleXMLElement($result);
// $dom = new DOMDocument();
// $dom->loadXML("lvl1.xml");
// $vol = dom->getElementsByTagName('Level1Data');
$vol=$xml->children->children('Level1Data');
$id = $xml["Volume"];
echo $id;
?>
Nothing gets returned and I am having a hard time reading the php documentation and their examples.
Thank you.

You can try to find the XML node using attributes() and foreach what attribute you want as per your requirements. If you need only single attribute then discard foreach looping.
<?php
$result =<<<EOT

<Content>
<Level1Data Tick="U" Currency="USD" TickSize="0.0001000000" TickValue="0" AssetClass="Equity" InstrumentState="Open" LastPrice="24.1550" LotSize="10"
MinPermittedPrice="0" MaxPermittedPrice="0" ClosePrice="24.0300" OpenPrice="24.1500" FirstPrice="24.1500"
HighPrice="24.7800" LowPrice="24.0000" MaxPrice="24.7800" MinPrice="24.0000" Volume="16238302"

EOT;
$volume = '';
$xml = new SimpleXMLElement($result);
foreach($xml->Content->Level1Data[0]->attributes() as $a => $b) {
if($a=='Volume'){
$volume = $b;
}
}
echo $volume;
?>

OR for single attribute e.g Volume
echo $xml->Content->Level1Data[0]->attributes()->Volume;

If you want to pickup Volume only, it can also be done as follows.
<?php
$result = <<<EOM
<Response>
<Content>
<Level1Data Tick="U" Currency="USD" TickSize="0.0001000000" TickValue="0" AssetClass="Equity" InstrumentState="Open" LastPrice="24.1550" LotSize="10"

Same variable from multiple XML

$var1 = new SimpleXMLElement('CSVXML/xvar.xml', null, true);
$var2 = new SimpleXMLElement('CSVXML/yvar.xml', null, true);
let's say I get variables from two diffrents XML files, in the first XML files
<Number>3698</Number>
<InternalNumber>1</InternalNumber>
<Name>Bob</Name>
<Number>3500</Number>
<InternalNumber>2</InternalNumber>
<Name>Mike</Name>
<Number>2775</Number>
<InternalNumber>3</InternalNumber>
<Name>Dan</Name>
in the second XML I get the followings
<player>3698</player>
<group>A</group>
I do this
$varID = $var1->Number;
$varnumber = $var2->player;
if ($varID == $varnumber ){
echo '$var1->InternalNumber';
}
is this possible ?
I simply want to put out a variable, is A for XML! = B from XML2, is there anyway possible to do that?
I found this working fine. tested link
<?php
$str = <<<XML
<items>
<item>
<Number>3698</Number>
<InternalNumber>1</InternalNumber>
<Name>Bob</Name>
</item>
<item>

</items>
XML;
$str2 = <<<XML
<item>
<player>3698</player>
<group>A</group>
</item>
XML;
$da = new SimpleXMLElement($str2);
$varnumber = $da->player;
$data = new SimpleXMLElement($str);
foreach ($data->item as $item)
{
$this_number = $item->Number;
//echo $this_number."-".$item->InternalNumber."-".$varnumber."\n";
if((int)$this_number == (int)$varnumber ){
$this_internalnumber = $item->InternalNumber;
echo $this_internalnumber."\n";
}
else{
echo "No Match found \n";

Hope this helps.

How to correct this code for adding selected xml tags from one xml source into another using xpath and php class methods

I want to read the following xml and find specific xml tags by their id values , Finally i want to copy these selected tags inside another xml using php user define class methods: sample given below:
<items>
<item>
<id>1</id>
<name>Item-1</name>
<price>10</price>
</item>
<item>
<id>2</id>
<name>Item-2</name>
<price>20</price>
</item>
<item>
<id>3</id>
<name>Item-3</name>
<price>30</price>
</item>
</items>
<customer>
<purchasedItems>
// add the xml here for the purchased Item chosen by id values
</purchasedItems>
</customer>
If customer purchased Item-1 and Item-3, then output will be:
<customer>
<purchasedItems>
<item>
<id>1</id>
<name>Item-1</name>
<price>10</price>
</item>
<item>
<id>3</id>
<name>Item-3</name>
<price>30</price>
</item>
</purchasedItems>
</customer>
i try with the following code which is not working :
<?php
header('Content-Type: text/xml');
class Items {
public static function addItem($purchasedItemsXml, $Items, $parentTag, $idTag ,$id)
{
$docSource = new DOMDocument();
$docSource->loadXML($Items);
$docDest = new DOMDocument();
$docDest->loadXML($purchasedItemsXml);
$xpath = new DOMXPath($docSource);
$result = $xpath->query("//{$idTag}[text()='{$id}']/parent::*");
$result = $docDest->importNode($result->item(0), true);
$items = $docDest->getElementsByTagName($parentTag)->item(0);
$items->appendChild($result);
echo $docDest->saveXML();
return ;
}
}
Updates: After changing Following code,Now Its Working Thanks to all.
class purchasedItems extends Items{
public static function addPurchasedItems($purchasedItemsXml, $Items, $parentTag, $idTag, $ids){
$count =0;
foreach ($ids as $id) {
if($count==0){
$xml = self::addItem($purchasedItemsXml, $Items, $parentTag, $idTag, $id);
}
else{
$xml = self::addItem($xml, $Items, $parentTag, $idTag, $id);
}
$count++;
}
echo $xml;
return ;
}
}
$Items = "<items>
<item>
<id>1</id>
<name>Item-1</name>
<price>10</price>
</item>
<item>
<id>2</id>
<name>Item-2</name>
<price>20</price>
</item>
<item>
<id>3</id>
<name>Item-3</name>
<price>30</price>
</item>
</items>";
$purchasedItemsXml = "<customer>
<purchasedItems>
</purchasedItems>
</customer>";
$ids = array(1, 3);
$parentTag = 'purchasedItems';
$idTag = 'id';
purchasedItems::addPurchasedItems($purchasedItemsXml, $Items, $parentTag, $idTag, $ids);
?>
as a beginner, i am sure i did some mistake, but i am now stuck at point.I want to do this using the existing given class hierarchy.please help me with this code.Thanks
You can achive this by using SimpleXML:
$xml = new SimpleXMLElement($purchasedItemsXml);
Then access like this: echo $xml->purchasedItems->item[0]->name;
To access children elements of a tag do this:
foreach($xml->purchasedItems->item as $item)
{
echo $item->name; //and other properties like this.
//if not sure try var_dump($item) here it will tell you.
}
Common mistake is to reference root element in your code, don't do that, or it won't work, you need to omit root element, in your case customer.
EDIT: To add items, find the items like I showed above, and add them like this:
$item = $xml->purchasedItems->addChild('item');
$item->addChild('name', 'SimpleXML Rocks just like that');
$item->addChild('id', '3');
echo $xml->saveXML();
Your “core” code is fine, but the classes construction is wrong (parent::addItem doesn't exist and addPayHead echoes one document for each added item).
This code — without classes — will work:
$ids = array(1, 3);
$parentTag = 'purchasedItems';
$idTag = 'id';
$docSource = new DOMDocument();
$docSource->loadXML($Items);
$docDest = new DOMDocument();
$docDest->loadXML($purchasedItemsXml);
$xpath = new DOMXPath($docSource);
foreach( $ids as $id )
{
$query = "//{$idTag}[text()='{$id}']/parent::*";
$result = $xpath->query( $query );
$result = $docDest->importNode($result->item(0), true);
$items = $docDest->getElementsByTagName($parentTag)->item(0);
$items->appendChild($result);
}
echo $docDest->saveXML();

Get data from an xml file

In a php script how to read and convert a XML document to an object and access the obtained object in order to get his data?
<?php
$xml ='<?xml version="1.0" encoding="UTF-8" ?>
<data request-id="ID">
<data name="Name1"
d1="0"
d2="0231234"
d3="32584">
<data name="Name2"
d4="231234"
d5="2012-06-06 18:18:10.000607"
d6="3b048653-aaa9-485b-b0dd-d16e068230e9" />
</data>
</data>';
$xml = simplexml_load_string($xml);
//how to get the data d1? or d4? from the obtained object
?>
You can use this snippet:
<?php
$xmlstring = file_get_contents($filename);
$xml = simplexml_load_string($xmlstring);
$json = json_encode($xml);
$object = json_decode($json);
Try using this function -
$xml ='<?xml version="1.0" encoding="UTF-8" ?>
<data request-id="ID">
<data name="Name1"
d1="0"
d2="0231234"
d3="32584">
<data name="Name2"
d4="231234"
d5="2012-06-06 18:18:10.000607"
d6="3b048653-aaa9-485b-b0dd-d16e068230e9" />
</data>
</data>';
function xmlToArray($input, $callback = null, $recurse = false) {
$data = ((!$recurse) && is_string($input))? simplexml_load_string($input, 'SimpleXMLElement', LIBXML_NOCDATA): $input;
if ($data instanceof SimpleXMLElement) $data = (array) $data;
if (is_array($data)) foreach ($data as &$item) $item = xmlToArray($item, $callback, true);
return (!is_array($data) && is_callable($callback))? call_user_func($callback, $data): $data;
}
$xml = xmlToArray($xml);
echo $xml['data']['#attributes']['d1'];
echo '<br/>';
echo $xml['data']['data']['#attributes']['d4'];
Use
$myxml = simplexml_load_string($xml);
echo $myxml->data[1]['d1'];
echo $myxml->data[1]['d2'];
echo $myxml->data[1]['d3'];
echo $myxml->data[2]['d4'];

Geting soap xsi:type from server response

I get response from SOAP server which has zero or more transactions of different types in each response.
Each transaction type is extension of base transaction type.
Different transaction types are processed differently.
Is there a way in PHP to get transaction type for each of transactions in response
(other then trying to figure difference in elements within each complex type)?
There is lot of types and lot of elements in each type....
Is there any class which could get this?
Following is just illustration...
<transactions xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ns2:type1">
<id>24111</id><something>00000000</something><name>Blah</name>
</transactions>
<transactions xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ns2:type8">
<id>24111</id><somethingelse>011</somethingelse>
</transactions>
I 'm not quite sure if this answer fits your question exactly. The following code snippet gets the type attribute value by their given namespaces and not the type of the namespaced value itself.
Done with PHP 's own Document Object Model.
<?php
$str = <<<XML
<content>
<transactions xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ns2:type1">
<id>24111</id>
<something>00000000</something>
<name>Blah</name>
</transactions>
<transactions xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ns2:type8">
<id>24111</id>
<somethingelse>011</somethingelse>
</transactions>
</content>
XML;
$doc = new DomDocument();
$doc->loadXML($str);
$nodeList = $doc->getElementsByTagName('transactions');
foreach ($nodeList as $element) {
$value = $element->getAttributeNS('http://www.w3.org/2001/XMLSchema-instance', 'type');
echo $value . "\n";
}
This will output the two given types "ns2:type1" and "ns2:type8".
I can parse your elements with simple_html_dom.
Here is the link for it.
An example is here :
<?php
include "simple_html_dom.php";
$html_nb = '
<transactions xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ns2:type1"><id>24111</id><something>00000000</something><name>Blah</name>
</transactions>
<transactions xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ns2:type8"><id>24111</id><somethingelse>011</somethingelse>
</transactions>';
function chtml($str){
if(strpos("<html>", $str) !== false)
return '<html><whole_code>'.$str.'</whole_code></html>';
else
return "<whole_code>".$str."</whole_code>";
}
function find_element_type($str){
if(preg_match_all("/\<(.*?)\>/i", $str, $matches))
return $matches[1][0];
else
return false;
}
function get_xsi_type($str){
if(preg_match_all("/xsi\:type\=\"(.*?)\"/i", $str, $matches))
return $matches[1][0];
else
return false;
}
$html = new simple_html_dom();
$html_2 = new simple_html_dom();
$html->load(chtml($html_nb));
$max_type = 10;
$element = $html->find('whole_code');
$e = $element[0]->innertext;
$html_2->load(chtml($e));
$k = 0;
while($html_2->find("whole_code",false)->children($k) != "")
{
$all = $html_2->find("whole_code",false)->children($k);
echo get_xsi_type($all) . "<br>";
echo find_element_type($all) . " : " .$all."<br>";
$k++;
}
echo "<hr>";
The result :
ns2:type1
transactions xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ns2:type1" : 2411100000000Blah
ns2:type8
transactions xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ns2:type8" : 24111011

How to delete a specific element from xml file

I want to delete:
<newWord>
<Heb>צהוב</Heb>
<Eng>yellow</Eng>
</newWord>
from:
<?xml version="1.0" encoding="UTF-8"?>
<xml>
<newWord>
<Heb>מילה ראשונה</Heb>
<Eng>first word</Eng>
</newWord>
<newWord>
<Heb>צהוב</Heb>
<Eng>yellow</Eng>
</newWord>
</xml>
so the output will be:
<?xml version="1.0" encoding="UTF-8"?>
<xml>
<newWord>
<Heb>מילה ראשונה</Heb>
<Eng>first word</Eng>
</newWord>
</xml>
I try to find the tag <newWord> and after this to go to child of it <Eng>yellow</Eng>
and if i found it by $searchString = 'yellow'; I should need to go to parrent of it and delete the element <newWord>.
I try to do it by the following code but I do not know ho to go to child of the <newWord>. many thx for helping.
this my code:
<?php
$del=true;
if ($del==TRUE){
$searchString = 'yellow';
header('Content-type: text/xml; charset=utf-8');
$xml = simplexml_load_file('./Dictionary_user.xml');
foreach($xml->children() as $child){
if($child->getName() == "newWord") {
if($searchString == $child['Eng']) {
$dom->parentNode->removeChild($xml);
} else {
echo('no match found resualt');
}
}
}
$dom = new DOMDocument;
$dom->preserveWhiteSpace = FALSE;
$dom->formatOutput = true;
$dom->load('Dictionary_user.xml');
$dom->save("Dictionary_user.xml");
$dom->saveXML();
header('Location: http://127.0.0.1/www/www1/ajax/ajax4/workwell/popus1.html');
}
?>
Try this:
$searchString = 'yellow';
$xml = simplexml_load_file('./Dictionary_user.xml');
foreach($xml->children() as $child){
if($child->getName() == "newWord") {
if($child->Eng == $searchString){
$dom = dom_import_simplexml($child);
$dom->parentNode->removeChild($dom);
}
}
}
echo $xml->asXML();
On this line
if($searchString == $child['Eng']) {
You're trying to compare the body of the child node, but it doesn't convert to a string automatically. It's still a SimpleXMLElement object, so the comparison fails.
Try explicitly casting it to a string to get the body of the tag.
if($searchString == (string)$child['Eng']) {
