      Guidelines and Netiquette   03/28/2017

      Posting Problems:   Having problems posting your topic? Read through this: To join, you agree to our terms and conditions and fill out and submit a registration form. An activation email will be sent to your email adress, so you'll need to verify your account. After that the account has to be validated by one of the moderators. This will mean that it can take up to a day to be activated. A couple of things to remember to ensure approval: Don't use an email address in one of those $2 four character .com domains eg. xyds.com. These will be deleted and the domain added to the banned list. Don't use an email address that is within a domain with a bad reputation for spam. A Google search is run on every email address and email domain. Don't sign up with an email address that doesn't exist, doesn't work or requires the sender to answer a quiz before their email can get to you. Put your country and or state and city in the signup form. Blank forms will go to the botton of the "to do" list. And make sure that your email address and your country match, saying you're from Alabama and using a .ru email address is not going to get you activated. After a membership is activated the first few posts will be monitored. Posting spam or unapproved topics described in the agreement results in an immediate ban. The email provider and the IP addresses associated with the account will be banned and all posts will be deleted. These strict measures have been deemed necessary to hinder spam. Sorry for any inconvenience this causes, but it's not liable to change. If, after reading this, you still can't post and don't understand why, contact one of the Moderators listed here.   Topic Guidelines   Including the following information can expedite an accurate response from board members: Must be a Specific Problem or Question related to web design and development Include Code in Question (wrap with   for small blocks of code and for longer blocks   ) Include Code Author Include Extra Notes/Modifications/Attempts Include web link to page/file when possible Content Guidelines   You may not post, upload, link to, or email any Content that contains, promotes, gives instruction about, or provides prohibited Content. Prohibited Content includes any Content that breaks any local, state, county, national or international law. Prohibited Content also includes: No direct or indirect advertising or websites, forums, products, services No hijacking of posts (do not post your question in someone elses) Content that infringes upon any rights [ex. MP3s and ROMs] (including, but not limited to, copyrights and trademarks) Abusive, threatening, defamatory, racist, or obscene Viruses or any other harmful computer software False Information or libel Spam, chain letters, or Pyramid schemes Gambling or Illicit drugs Terrorism Hacking or cheating for internet/online games Warez, Roms, CD-Keys, Cracks, Passwords, or Serial Numbers Pornography, nudity, or sexual material of any kind Excessive profanity Invasive of privacy or impersonation of any person/entity Hacking materials or information Posting Tips   There are more BBcodes than there are buttons for on the reply menu. To get the full list, click "BB Code Help" underneath the clickable smilie face menu. Use   for small snippets of code Use   for lengthy snippets of code Use   if your snippet is HTML (optional) Use   if your snippet is SQL (optional) Rules of Conduct   Be nice. There's no need for calling someone stupid if they ask an 'easy' question. Keep your avatars and signatures absolutely child friendly. We have a younger audience on this forum. Keep your language appropriate for the same reason above. Do not PM moderators for help on the forum. Post on the topic, or create a new one.   Spam:   Recently, as you have all without doubt noticed, we have had lots of spam and advertisement on the forum. Therefore, we'd like to alert you as to what to do when you have found any of the aforementioned annoying messages: it. Immediately. Give a clear reason, please, if the advertising is not evident. DO NOT POST! Report, let the post stay as is, and we will get to it, meanwhile if you continue to post as normal in the other threads, it won't be on the top so long. Refrain from PMing the member. This won't help at all, as they are most likely spambots anyway. Thank you.       Images in signatures:   After thinking of users on dial-up, we have decided to enforce the following rules regarding signatures. Please pay heed to them. Respecting these rules is respecting the members on this forum with dial-up. Signature rules: No animated images AT ALL. No matter the amount of animation. Maximum image widthxheight: 300x150 Maximum image (file) size: 15kb Use calm colors. Do not use highly contrasting images in your signature, as this can get really annoying when seeing several posts from one member in the same thread. The same prohibited content goes for images as for posts. Lastly, use common sense. No lengthy signatures please. Save us some scrolling. Thank you.       Links in signatures:   Please understand that w3schools.com only exists because of voluntary work and is barely supported by the advertising littered throughout the tutorials and the forum. So, please, stop advertising other sites. DO not post links that drive traffic away from the w3schools domain - especially to a site that offers similar if not identical information. Please help support the site by keeping individuals on it. Thank you. Here are some guidelines as to what you can put in your signature: w3schools links --> allowed w3.org links --> allowed browser links --> allowed html editor links --> allowed personal sites --> allowed tutorial sites competing with w3schools --> NOT allowed sites completely irrelevant to webprogramming and this forum --> NOT allowed   Thanks for understanding, and for taking the time to read this. ~W3Schools Modstaff~

I'm stuck on xml to xsl path ?

Recommended Posts

davej    244

So I'm trying to understand the basics... If I put an xml file and an xsl file in a folder together with the xml file containing a path to the xsl file, shouldn't this work sort of like an HTML file and CSS file? I was expecting a rendered output similar to the output you get in the "XSLT Tryit" editor here: http://www.w3schools...tfile=cdcatalog

<?xml version="1.0" encoding="utf-8"?><?xml-stylesheet type="xsl" href="myxslfile.xsl"?><!DOCTYPE Artist [etc...

But it doesn't work. The browser does not format it. Using type="text/xsl" does not fix it. The same pair of files can be pasted into the "XSLT Tryit" page and there they produce a formatted result.

The type should be "text/xsl"With the information you've provided, I can't see how it wouldn't work. You'll have to post all the code, or show an example online.

Oh, it apparently didn't like my filename. Also it didn't like n b s p being in there. I need n b s p although I guess I can add padding/margin or something. What is the best approach for spacing out displayed elements? & n b s p ; didn't work but & # 160 ; works. I'm happy. -- edit Hmmm. Maybe I'm not happy. So DTD's are obsolete? Do I just replace the DTD with a Schema or do I need to keep that separate and have another header path statement such as...

<?xml version="1.0" encoding="ISO-8859-1"?><ArtistListxmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:noNamespaceSchemaLocation="myxmlschema.xsd">

Also in the xsl stylesheet, how do I print an attribute?

yes.

With "@" in front of the node name.

Ok, thanks! I'm still having trouble with namespaces or paths or something. Why do namespaces need a URI and what is the meaning of the URI? Does it look for the file at the location of the URI path? I have three files in the same folder... but it isn't working. I think the XSD, the XSD reference, or the XSD namespace is the problem. The same XSL file works fine when I use a DTD. If I change the order of the two references in the top of the XML file I can either see the data or the formatting, but not both. prob12.34d.xml file:

<?xml version="1.0" encoding="utf-8"?><ArtistListxmlns="http://www.w3schools.com"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.w3schools.com prob12.34d.xsd"><?xml-stylesheet type="text/xsl" href="prob12.34d.xsl"?><Artist ArtistID="1">  <ArtistName>	<FirstName>Joan</FirstName>	<LastName>Miro</LastName>  </ArtistName>	<Nationality>Spanish</Nationality>	<DateOfBirth>1893</DateOfBirth>	<DateDeceased>1983</DateDeceased></Artist><Artist ArtistID="2">  <ArtistName>	<FirstName>Wassily</FirstName>	<LastName>Kandinsky</LastName>  </ArtistName>	<Nationality>Russian</Nationality>	<DateOfBirth>1866</DateOfBirth>	<DateDeceased>1944</DateDeceased></Artist></ArtistList>

prob12.34d.xsd file:

<?xml version="1.0" encoding="utf-8"?><xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"elementFormDefault="qualified"attributeFormDefault="unqualified"> <xs:element name="ArtistList"><xs:annotation>  <xs:documentation>???</xs:documentation></xs:annotation><xs:complexType><xs:sequence>  <xs:element name="Artist">  <xs:complexType>  <xs:sequence>	<xs:element name="ArtistName">	<xs:complexType>	<xs:sequence>	  <xs:element name="FirstName" type="xs:string"/>	  <xs:element name="LastName" type="xs:string"/>	</xs:sequence>	</xs:complexType>	</xs:element>	<xs:element name="Nationality" type="xs:string"/>	<xs:element name="DateOfBirth" type="xs:date"/>	<xs:element name="DateDeceased" minOccurs="0" type="xs:date"/>  </xs:sequence>  <xs:attribute name="ArtistID" type="xs:positiveInteger" use="required"/>  </xs:complexType>  </xs:element></xs:sequence></xs:complexType></xs:element></xs:schema>

prob12.34d.xsl file:

<?xml version="1.0" encoding="utf-8"?><xsl:stylesheetversion="1.0"xmlns:xsl="http://www.w3.org/1999/XSL/Transform"xmlns:fo="http://www.w3.org/1999/XSL/Format"> <xsl:output method="html"/> <xsl:template match="/"><html><head><title>Artists List</title><style type="text/css">body {background-color: gray;}.cname {font-size: 14pt;color: black;background-color: blue;font-weight: bold;padding: 5px;}.cyears {font-size: 10pt;font-style: italic;color: black;}.cdetail {font-size: 10pt;color: green;background-color: white;padding-left: 15px;}</style></head><body><h1>Artist List</h1><hr/><xsl:for-each select="ArtistList/Artist"><div class="cname"><xsl:value-of select="@ArtistID"/>:  <xsl:value-of select="ArtistName/FirstName"/><xsl:value-of select="ArtistName/LastName"/>  <span class="cyears">(Born:<xsl:value-of select="DateOfBirth"/>Died:<xsl:value-of select="DateDeceased"/>)</span></div><div class="cdetail">Nationality:<xsl:value-of select="Nationality"/></div><hr/></xsl:for-each> </body></html></xsl:template></xsl:stylesheet>

No difference in using either of the following...

<ArtistListxmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:noNamespaceSchemaLocation="prob12.34d.xsd">

or

<ArtistListxmlns="http://www.w3schools.com"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.w3schools.com prob12.34d.xsd">

The proper order is to have the PI ("Processing Instruction"; the "<?" thingy) before the root element.Also, for a validator to recognize your declarations, the namespaces everywhere need to match. In this case, your elements are not in a namespace, so the "noNamespaceSchemaLocation" is the proper attribute to use, i.e.

<?xml version="1.0" encoding="utf-8"?><?xml-stylesheet type="text/xsl" href="prob12.34d.xsl"?><ArtistListxmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:noNamespaceSchemaLocation="prob12.34d.xsd">

You're not supposed to see both the data and the formatted HTML... The PI is used exactly to tell the browser to hide the data in favor of whatever the result of the XSLT transformation is (which in your case is an HTML page, but could be an SVG instead for example).Also, no browser does either DTD or Schema validation, so you're not going to get any schema related errors in a browser. For that, you'd need to use the server. e.g. PHP's DOMDocument::schemaValidate() which, as you might be guessing, ignores your XML declaration too. So what's the point of that declaration you ask? IDEs - they can offer you auto completion based on the declared schema, and some can even validate your document "on the fly", and tell you an element is invalid at that location as soon as you write it out.

Oh heck, it did work. I must not have tried the noNamespaceSchemaLocation in this order...

<?xml version="1.0" encoding="utf-8"?><?xml-stylesheet type="text/xsl" href="prob12.34d.xsl"?><ArtistListxmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:noNamespaceSchemaLocation="prob12.34d.xsd">

Thanks! But now what is the match-up that is needed for the use of a namespace? I obviously had it wrong taking headers right from the examples here: http://www.w3schools...hema_schema.asp How would I need to modify the earlier files posted above to fix the namespace problem? Thanks. This does not work...

<?xml version="1.0" encoding="utf-8"?><?xml-stylesheet type="text/xsl" href="prob12.34d.xsl"?> <ArtistListxmlns="http://www.w3schools.com"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.w3schools.com prob12.34d.xsd"> <Artist ArtistID="1">  <ArtistName>	    <FirstName>Joan</FirstName>	    <LastName>Miro</LastName>  </ArtistName>	    <Nationality>Spanish</Nationality>	    <DateOfBirth>1893</DateOfBirth>	    <DateDeceased>1983</DateDeceased></Artist><Artist ArtistID="2">  <ArtistName>	    <FirstName>Wassily</FirstName>	    <LastName>Kandinsky</LastName>  </ArtistName>	    <Nationality>Russian</Nationality>	    <DateOfBirth>1866</DateOfBirth>	    <DateDeceased>1944</DateDeceased></Artist></ArtistList>
