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
< and > . 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><![CDATA[<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')" />]]></image>
<name>orange top</name>
<desc>an orange jacket</desc>
<size>large</size>
<price>14.50</price>
</item>

I've not experienced this with using any DOM functions, but if we
can
see your code it might help us.
Thanks,

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,

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.
