 | well. im guessing it doesn't save the image's because their locations are relative to somewhere else.. if you're using the File>Save As.. in Internet explorer, you have to choose "Web page,complete" rather than "Web page, HTML only".

[url]http://www.w3.org/TR/xslt[/url] ...this is a good reference [url]http://www.w3schools.com/xsl/[/url] ..and this is a good introduction I would advise building the pages using an offline XSLT processor, as client side (browser) XSLT processors are at best; bad.

| | well, a good browser should be able to either allow a user to increase font sizes, or override parts of a stylesheet (font-size/colors etc)... a really good browser (like Opera) will handle all of the calculation for resizing things relatively, that is it can zoom in and out on content, … |
 | Re: css Direct child selectors are interesting: [code] div.parent>div.child{}[/code] Will apply to all divs of class child within divs of class parent, BUT only if they are direct children. However: [inlinecode]table>tr>td[/inlinecode], doesn't work, unless you use: [inlinecode]table>tbody>tr>td[/inlinecode]... REGARDLESS of whether or not you have a tbody tag in your markup. Rude, no? |

I don't know whether system() works, but I imagine it does.. |
| | Re: Expandable html? You could do it, but you'd need some Javascipt to create the expand/collapse buttons, and (probably) some XSL to convert the XML into HTML. Non-JS alternatives would involve some messy backend stuff with query strings... (and heck, if you're using client-side XSL transformations, getting hold of the query string is … |
| | i think the property you're looking for is 'checked'.. I don't know whether forms.elements.xxx will give you a [I]named[/I] object handle in return... if your input is set up: <input name="termsandconds" type="check"/>, you should be able to access it as bookingform.termsandconds.

| | well, if you are submitting your page by "typing" (pasting) it into the box on the W3C site; it will probably complain bitterly about the php constructs. if you access your page on the internet, that php code should all become (X)HTML, and some of those errors will likely go … |
| | well, do you want to know cgi/perl? or do you want a solution that uses neither cgi, nor perl? methinks, you'll find it easier to learn cgi (perl or php) than to find a solution that doesn't use the cgi (or another server side solution) in one way or another. … |
 | what do you mean by block? subroutine scope or method scope? if you do one regex then another within a subroutine, you don't need to reset $1,$2,$3 etc, the next regex will overwrite the old values, if you want to preserve them, make a named copy of each one: my($match1) … |

| | the way you're using them, they are synonymous. arrays store indexed values, but they can also store values by associative keys. Objects can store values by associative keys also; so, when you write person[0] = la, you're creating a key (0) which you can then use to retrieve the Person-class … |
| | the reason you can't do that is because on most filesystems a running exe "locks" its file for write operations. if you were to directly overwrite parts of an application while it was running it would probably crash anyway. you could recompile the application using a command line call and … |
| | I'm putting this here because I don't really know where would be best, if I could pick a language-categorised solution I probably wouldn't be asking atall...I don't need a solution so much as a pointer. How do you get a file from a user's computer to a server, from a … |
