I have an xml sheet with some data and some images that i want to collect only a part using xslt.
However, there is one image with a particular classname that i would like to collect especially.
For example, the XML says:
<img class="itemImage" height="130" src="image.png" width="195"/>
How do I get the src attribute of this image by selecting it by classname with XPath?
This should work : //img[#class="itemImage"]/#src
This XPath will return the src of the first img node which has a src and has the specified class
(//img[#class="itemImage"]/#src)[1]
However, if you know anything at all about the structure of the xml, you can and should avoid the use of //, which requires the entire document to be scanned.

I need to create the element and then delete it. Is there a way to find the element by it's text after it was created?
The xpath of the element is //div[#id='mif-tree-6']/span/span[3].
You can use xpath for it for example. Like:
//div[#id='mif-tree-6']//span[contains(text(),'your_text_here')]
UPDATE
Please provide an example of your html. It is possible to find a parent of your element with xpath and after that to find all the childs. For example your html =
<div id='lol'>
<div>first_item</div>
<div>second_item</div>
<div>third_element</div>
</div>
You get an array of elements with xpath =
//div[contains(text(),'first_')]/../div
So you can do something like:
click | //div[contains(text(),'first_')]/../div[2]
BUT if there are a lot of brothers-elements to find by text of one sibling it will be necessary to use loop to get every of them.
Once again. If you will provide full information about what are you doing and an example of your html it will be much easier to suggest.
so will something like this work using Hpple Xpath
//a[4]
The fourth tag in a html tree?
Or do i need to do it programmatically by counting in a for() loop?
The XPath for the fourth <a> in an HTML document is:
(//a)[4]
Your example //a[4] will produce a set of all <a>s that are the fourth <a> in their respective parent, and that is not what you want here.

I have an standard image upload in TYPO3 Backend, that allows more than 1 image upload.
So I have an image database field with data like that: "image1.jpg,image2.jpg".
In Frontend, I can explode the field, send the array to fluid, and output it in a fluid:for each like that:
<f:image src="uploads/tx_myext/{image}" />
First question is: is there maybe some fancy new Extbase or Fluid Magic, that creates image objects right from database?
Second question: if I have a huge 2MB image and make a fluid:image output with width=100, is it just scaled in browser, or is it really downsized using ImageMagick?
Comma list to array:
Unfortunately as I can see in Extbase 4.7 there is still no ViewHelper for iterating comma separated strings. You have two options: write custom ViewHelper or stay with the way you are using.
TIP: To avoid passing additional params (especially when you have many comma separated fields there and/or using many Partials for rendering the view) I'm adding a public field to my model. Without representation in TCA it will be considered as transient, ie:
/**
* #var array
*/
public $imagesArray;
and then just filling it in controller right before assigning so I can access it as {project.imagesArray} in the view:
public function showAction(Tx_Myext_Domain_Model_Project $project) {
$project->imagesArray = explode(',', $project->getImage());
$this->view->assign('project', $project);
}
view
<f:for each="{project.imagesArray}" as="image">
<f:image src="uploads/tx_myext/{image}" width="200" height="200m" alt="" />
</f:for>
Most probably you are using quite similar approach...
Image resizing:
It's easiest just to ... check. ImageMagick hashes the name of the resized image and stores it in the temp folder by default, so if in code preview you see the path like: typo3temp/pics/cd27baa408.jpg instead of uploads/tx_myext/photo123.jpg that means it was converted with IM. And yes, image ViewHelper uses the IM.
You can even add perform simple calculations by giving value as width="200m" or width="200c" from viewhelper's phpdoc: See imgResource.width for possible options
Now I created a ViewHelper in Typo3 Forge as I think processing of images as they come from database would be quite usefull.
And I added imageLinkWrap for JS Window.

I have this xml as part of the responseXml of an Ajax call:
<banner-ad>
<title><span style="color:#ffff00;"><strong>Title</strong></span></title>
</banner-ad>
When I used this jQuery(responseXml).find("title").text(); the result is "Title".
I also tried jQuery(responseXml).find("title:first-child") but the result is [object Object].
I want to get the result:
<span style="color:#ffff00;"><strong>Title</strong></span>
Please let me know how to do this in jQuery.
Thanks in advance for any help.

Your problem is that you cannot simply append nodes from one document (the XML response) to another (your HTML page). The issue is two-fold:
You can use jQuery to append nodes from the XML document to the HTML page. This works; the nodes appear in the HTML DOM, but they stay XML nodes and therefore the browser ignores the style attribute, for example. Consequently the text will not be yellow (#ffff00).
As far as I can see, jQuery offers no built-in way to get the XML string (i.e. a serialized node) from an XML node. jQuery can handle XML documents quite well, but there is no equivalent to what .html() does in HTML documents.
So to make this work we need to extract the XML string from the XML document. Some browsers support the .xml property on XML nodes (namely, IE), the others come with an XMLSerializer object:
// find the proper XML node
var $title = $(doc).find("title");
// either use .xml or, when unavailable, an XMLSerializer
var html = $title[0].xml || (new XMLSerializer()).serializeToString($title[0]);
// result:
// '<title><span style="color:#ffff00;"><strong>Title</strong></span></title>'
Then we have to feed this HTML string to jQuery so new, real HTML elements can be created from it:
$("#target").append(html);
There is a fiddle to show this in action: http://jsfiddle.net/Tomalak/QWHj8/. This example also gets rid of the superfluous <title> element.
Anyway. If you have a chance to influence the XML itself, it would make sense to change it:
<banner-ad>
<title><span style="color:#ffff00;"><strong>Title</strong></span></title>
</banner-ad>
Just XML-encode the payload of <title> and you can do this in jQuery:
$("#target").append( $(doc).find("title").text() );
This would probably work:
$(responseXml).find("title").html();
I am new to iphone development.I want to ignore CDATA tag while parsing because it consider the HTML tag following it as text.Since i want to display the content alone ,i want my parser to ignore CDATA tag.My source code is
[CDATA[<br /><p class="author"><span class="by">By: </span>By Sydney Ember</p><br><p>In the week since an </p>]].
Is there any way to ignore CDATA tag?
Is there any way to parse my source twice so it displays only the content?
Please give me some sample code.Please help me out.Thanks.
If you treat the CDATA content as XML instead of CDATA then your parser will throw an error (since your HTML is a weird mix of XHTML and HTML and is not well formed).
If you want to get the HTML, then parse the XML, extract the text content of the node, then parse that text as HTML.
There is no way to ignore the CDATA tag - it's part of the xml spec and parsers should honour it.
If you don't like the idea of this answer to your earlier question, you could get the contents of the CDATA section and parse it as XML again. However, this is highly not recommended! You don't know that the contents of the CDATA are going to be valid xml (they're probably not).
If you can 100% guarentee that the CDATA section contains the form you have above, you could probably use some string manipulation to get the data out (i.e. string replace '<span class="by">By: </span>' with '') but again, this will almost certainly break if the CDATA contents change.
Where is the xml coming from? It's a better idea to talk to owner of the service and get them to send you instead of description something like
