I want to store the contents of an xml file in the database. Is there an easy way to do it?
Can i write some script that can do the task for me?
The schema of the XML file looks like this:
<schedule start="20100727120000 +0530" stop="20100727160000 +0530" ch_id="0210.CHNAME.in">
<title>Title_info</title>
<date>20100727</date>
<category>cat_02</category>
</schedule>
One thing to note is:
How do I read the start time? I need the time +0530 added to the time?
Thank you so much.
You'll probably want to create a table called schedules that matches your data, then read the contents of the XML file with an XML parser of your choice. SimpleXML might be the right tool for this job.
As for the dates, I recommend you try using the function date_parse_from_format().
look up simple_xml on the php page - off hand I'm not too hot on it, but basically you will end up with a loop which will add your data to an object eg:
$xml
and you will be able to call tags as such $xml->schedule->title $xml->schedule->date and $xml->schedule->category and you will be able to call attributes as such $xml->schedule[start] but you might wanna check that.
I had to do this recently for a client, and this was the best way I could find. The attributes may be tricky - I can't quite remember but you might have to look into namespaces and such... anyway, find simple_xml and you're on the right tracks.

I have a simple PHP application, which uses MySQL DB, but I think that maybe the using of DB is needlessly for such easy operations.
Anyway, I hove some problems with the XML operations.
Let's say I want to have XML structure like this:
<root>
<experiment>
<name>test</name>
<accessCount>5</accessCount>
<downloadEntry>
<date>2015-11-27</date>
<comment>comment</comment>
</downloadEntry>
<downloadEntry>
<date>2015-11-28</date>
<comment>comment</comment>
</downloadEntry>
</experiment>
</root>
Now I would like to know, how to do these operations:
Count download entries (count of downloadEntry nodes) of experiment with name "test". Via XPATH?
Get download entries of experimetn with name test - but I would like to have pagination on this. So get download entries somehow like LIMIT 0,5.
The biggest problem is that, when there are no experiments - so the XML is , the loading of XML with simplexml_load_file fails. I can't open it. Yes, I can add the condition - if the XML is empty, donť open it. But I need to write to it and can't write if it isnť open.
Is there a solution for that?
Thanks everyone
I'm trying to figure out how to take a simple custom xml file (its actually an EML file, but simpeXML works with it anyway) and take tagnames and the text that follows (i think simpleXML calls them children) and put them into a MAP, with key/value pairs. I've looked at some examples on this site and others about converting to arrays and such but they all seem extremely complicated for my needs. I should note that my custom xml does not contain ANY attributes and this conversion only needs to work with MY custom xml file and not any others ever.
So a simple example of my eml file is here
<lesson>
<unit>4</unit>
</lesson>
So then basically what I would want is a MAP, or whatever a key/value collection is called in php that would give me:
Map[0](lesson,null)
Map[1](unit,4)
It's important that I get the null values (or an empty string is ok too), so I can verify that the eml file is valid. I need to validate it with php, not using a namespace validator or a dtd file or however that is done. So the first key/value pair, or the root tag, HAS to be lesson, and then ill also verify that there is a unit tag, then a title tag, then at least one other type of tag etc...I can do that easy if i can get everything into a key/value collection. Also, there are many tagnames that are the same, so keys should be not-unique. However for the value, they should be unique, but only to the tag name. So unit can only one one "4", but another tag, lets say imageID could also have "4". This is not a requirement but a "nice to have" and I can probably figure that out if its not simple. But if its REALLY hard then I will skip it all together.
I hope this makes sense.
And no, I don't think Im allowed to use json. I'm sure it can be done in simpleXMl but if its impossible, then please provide a method to do it in json (assuming that json is included with PHP and not an extension that has to be loaded).
This is university homework, so I can't use extensions or anything else that would require anything beyond what comes with the XAMPP basic package (php, mysql, apache etc...).
Really surprised I got no votes or views or answers or anything on this. I did figure this out in the end. Oh yeah...got the tumbleweed badge for this too!
Anyway the answer was actually quite simple. I used the simplexml_load_file function in PHP which actually supports any kind of xml-style. So after running this,
$eml = simplexml_load_file("unit.eml");
I then did things like this
foreach ($eml->children() as $child)
$tag = $child->getName();
$tagInfo = $child;
And used $tag and $tagInfo to iterate through my eml and get everything I needed.
I am trying to build a very simple price comparison script.
Until now, I wrote a code that gets some product xml feeds from shops and with the help of XSLT I create a single-global xml of all those input XMLs. I use the XSLT because the shops have different names for elements.
Now I want to take it one step further and I want to create a search form that will display me the products let's say I have the term "laptop".
I know how to create a form, but I need a coding guidance to understand how to make it to search in my XML file (products.xml) and display let's say the
Thank you
You might want to check out http://php.net/manual/en/class.xmlreader.php
Using that it is pretty easy to navigate through an XML file and grab all the info you need.
EDIT:
On second thought, http://php.net/manual/en/book.simplexml.php is a MUCH simpler way to achieve what you're trying to do. Hence the name, I guess ;)
You can use SimpleXML library to parse your xml file. In my opinion SimpleXML is easier to use than xmlreader. Though SimpleXML is introduced on php5.
I have an XML feed coming in:
<?xml version="1.0" encoding="UTF-8"?><product>
<name>John</name>
<contact_email>john#johnson.com</contact_email>
<contact_telephone>01234 567</contact_telephone>
<url>www.johnsone.com.com</url></product>
I need to get this loaded to MySQL using php - have seen a few examples but all of them take a file saved locally.
My feed is taken from the internet so changes all of the time. Does anybody have any suggestions where to start?
Thanks
First you'll need to define a data model. Then you'll need an xml parser to parse the feed, extract the data and populate your data model. Then you'll need to pass your model object to a DAO which writes the data to your database.
If it's taken from the internet you can just do
<?php
$feedData = file_get_contents('http://mywebsite/myfeed.xml');
?>
if you want to parse the data and store then
create a table for product
parse the xml and get the fields
insert into db or update existing data
so, what's your problem?
To be a bit more specific:
You'll obviously need to set up a table and database structure. I'm going to assume you have, or at least can figure out how to, set this up, and how to write to a database. If not, there are plenty of tutorials on that that should be plenty helpful. You'll need to use PHP's built-in MySQL library.
For parsing the XML you will probably want to use SimpleXML. It's not clear how your feed is coming in, but SimpleXML has the simplexml_load_string function that will let you pass it a string containing an XML document, however you get it, for parsing.
From there, you can just take the parsed XML and write it to your database. Any examples that use SimpleXML with a local file should be pretty easy to adapt using simplexml_load_string instead of simplexml_load_file, and doing whatever you're already (presumably) doing to get the data from this feed.
I have an xml feed that I have to check periodically for updates. The xml consists of many elements and I'm looking to figure it out which is the best (and probably faster) way to find out which elements suffered updates from last time I've checked.
What I think of is to check first the lastBuildDate for modifications and if it differs from the previous one to start parse the xml again. This would involve keeping each element with all of its attributes in my database. But each element can have different number of attributes as well as other nested elements. So if it would be to store each element in my database what would be the best way to keep them ?
That's why I'm asking for your help :) Thank you.
Most modern databases will store your XML as a blob if you like. (You tagged PHP... MySQL? If so, use MEDIUMTEXT.) Store your XML and generate a diff when you get a new one. If you don't have an XML diff tool, canonicalize both XML listings then run a text diff.
