XML Dom Problem

[bailo81]

Ok,

I have code in the same format as this in an xml file...

<notes>
<note>
<username>John Smith</username>
<age>21</age>
<comments>Blah Blah Blah</comments>
</note>
<username>Joe Blogs</username>
<age>35</age>
<comments>Test Test Test</comments>
</note>
</notes>

I know how to for example get all the usernames using

$dom->get_elements_by_tagname('username')

and then looping through them but what i would like to learn to do would be to get it to display is like this...

Username: John Smith
Age: 21
Comments: Blah Blah Blah

for each of the users. Any suggestions?

This works but I am sure some one will have a much better option for you.

You need to change you XML to

<?xml version="1.0" encoding="UTF-8"?>
<notes>
<note>
<username>John Smith</username>
<age>21</age>
<comments>Blah Blah Blah</comments>
</note>
<note>
<username>Joe Blogs</username>
<age>35</age>
<comments>Test Test Test</comments>
</note>
</notes>

Here is the code

<?php
$xml_filename = "yourXml.xml";
$dom = new DOMDocument();
$dom->load($xml_filename);
$loop=1;
$usernametag=$dom->getElementsByTagName('username');
 foreach ($usernametag  as $value) {
$username[$loop]= $value->textContent;
$loop++;
}
$loop=1;
$agetag=$dom->getElementsByTagName('age');
 foreach ($agetag  as $value) {
$age[$loop]= $value->textContent;
$loop++;
}
$loop=1;
$commentstag=$dom->getElementsByTagName('comments');
 foreach ($commentstag  as $value) {
$comments[$loop]= $value->textContent;
$loop++;
}

for ($i=1; $i<$loop; $i++) {
	echo "Username:".$username[$i]."<br/>";
	echo "Age:".$age[$i]."<br/>";
	echo "Comments:".$comments[$i]."<br/>";

}
?>

Another good way to display XML in a better format is by use of XSL

[_theworks]

If you can install a 3rd party lib or get your hosting provider to get SimpleXML installed it makes parsing XML a brease...

all you would need to parse your xml is..

$xml = simplexml_load_file( "xml.xml" ) ;

$notes = $xml->notes;

foreach $notes->note as $item) {
 echo 'Username: '.$item->username.'<br />';
 echo 'Age: '.$item->age.'<br />';
 echo 'Comments: '.$item->comments.'<br />';
}

I have a similar thing going on in another topic;

I would like to know how to display each "foreach" one at a time on the same page using like navigational buttons on the bottom. much like javascript and using datafld's in IE. Same concept

[MarkBad311]

Do I have to put the foreach statement inside of a block and at the end of the block have like two submit buttons with two different values and a if {}else{} block redirecting it back to the for each block?

If so how will I make sure it doesn't parse the same ones over and over?
