Hiya, I'm writing an app that let's my client upload images, the image html code is added to an XML file. Take a look at the <image> element below: <item Code="e1022"> <code>e1022</code> <image><![CDATA[<img src="uploads/image2.jpg" alt="Homepage Image" width="124" height="70" />]]></image> <name>Blue Ski Trousers</name> <price>8.99</price> </item> Now, whenever PHP writes this to the XML files, it turns the < and

into

&lt; and &gt; . which means it does not display on the webpage. How can I prevent this from happening ?

str_replace?

Does the xml string get passed to htmlentities() or a similar function before it is sent to the browser? That would explain the substitutions. I saw an xmlentities() variation mentioned somewhere.

Hi Bob, Nope the string doesn't get passed into any function. Here is the XML: _________________________________________________________________ <?xml version="1.0" encoding="UTF-8"?> <clothes> <item Code="e1021"> <code>e1021</code> <image><![CDATA[<img src="uploads/image1.jpg" alt="Homepage Image" width="124" height="70" border="1" onclick="MM_openBrWindow('uploads/ image1.jpg','Preview','width=680,height=520')" />]]></image> <name>Red Jacket</name> <desc>An adult sized red jacket</desc> <size>adult</size> <price>12.99</price> </item> <item Code="e1022"> <code>e1022</code> <image><![CDATA[<img src="uploads/image2.jpg" alt="Homepage Image" width="124" height="70" border="1" onclick="MM_openBrWindow('uploads/ image2.jpg','Preview','width=680,height=520')" />]]></image> <name>Blue Ski Trousers</name> <desc>A pair of Blue Ski Trousers</desc> <size>child</size> <price>8.99</price> </item> </clothes> ________________________________________________________________ Now the image tags I have written here I have done manually, but when I use PHP using DOM they come out like this (note the image element): <item Code="e1024"> <code>e1024</code> <image>&lt;![CDATA[&lt;img src="uploads/image4.jpg" alt="Homepage Image" width="124" height="70" border="1" onclick="MM_openBrWindow('uploads/ image4.jpg','Preview','width=680,height=520')" /&gt;]]&gt;</image> <name>orange top</name> <desc>an orange jacket</desc> <size>large</size> <price>14.50</price> </item> Matthew Croud Studio Obvious Print Solutions Limited Unit 3 Abbeygate Court Stockett Lane Maidstone Kent ME15 0PP T | 0845 094 9704 F | 0845 094 9705 www.obviousprint.com

I've not experienced this with using any DOM functions, but if we can see your code it might help us. Thanks, Ash http://www.ashleysheridan.co.uk -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Well i'll pop the PHP down here, i'll trim it as much as i can: ________________________________________________________________________ $code = $_POST['code']; $name = $_POST['name']; $desc = $_POST['desc']; $size = $_POST['size']; $price = $_POST['price']; #load an XML document into the DOM $dom = new DomDocument(); $dom -> load("items.xml"); #create elements $Xitem = $dom -> createElement("item"); $Xcode = $dom -> createElement("code"); $Ximage = $dom -> createElement("image"); $Xname = $dom -> createElement("name"); $Xdesc = $dom -> createElement("desc"); $Xsize = $dom -> createElement("size"); $Xprice = $dom -> createElement("price"); #create text nodes $Xcodetext = $dom -> createTextNode($code); $Ximagetext = $dom -> createTextNode( "<![CDATA[<img src=\"uploads/ $UploadName\" alt=\"Homepage Image\" width=\"124\" height=\"70\" border=\"1\" onclick=\"MM_openBrWindow('uploads/ $UploadName','Preview','width=680,height=520')\" />]]>" ); $Xnametext = $dom -> createTextNode($name); $Xdesctext = $dom -> createTextNode($desc);

$Xsizetext =    $dom -> createTextNode($size);
$Xpricetext =    $dom -> createTextNode($price);

#append the text nodes to the inner nested elements $Xcode -> appendChild($Xcodetext); $Ximage -> appendChild($Ximagetext); $Xname -> appendChild($Xnametext); $Xdesc -> appendChild($Xdesctext);

$Xsize    -> appendChild($Xsizetext);
$Xprice    -> appendChild($Xpricetext);

#append the inner nested elements to the <item> element $Xitem -> appendChild($Xcode); $Xitem -> appendChild($Ximage); $Xitem -> appendChild($Xname); $Xitem -> appendChild($Xdesc); $Xitem -> appendChild($Xsize); $Xitem -> appendChild($Xprice); $Xitem -> setAttribute("Code",$code); #append the <title> element to the root element $dom -> documentElement -> appendChild($Xitem); #create a new enlarged xml document $dom -> save("items.xml"); _____________________________________________________

It looks like it's because you are creating an image object by appending a text node inside CDATA to it. My guess is that a text node will have the contents automatically made 'safe' for the XML entities which are <,

, &, etc.

Why are you appending the child item like this? What's wrong with adding it as a proper object, attributes and all? Thanks, Ash http://www.ashleysheridan.co.uk

Hi Ash, Thanks for getting back to me, In all honesty this method is what's implemented in the course book i've been following. I been using XML longer and i've never had this issue using image tags before and getting the output I expected. Is there a way around this safety mechanism ? Otherwise i'll have to think of another way of doing this. Cheers.
