I'm writing some rules in Diazo. I want, in case the user browses the "viewer" section (a browser view, not a real plone folder), to drop the "selected" class for the "home" tab in the globalnav and put "selected" class for the "viewer" tab.
<replace css:content="#portal-globalnav" css:theme="#portal-globalnav" />
<drop if-path="viewer/"
css:content="#portaltab-index_html"
attributes="class" />
<xsl:template if-path="viewer/"
match="//li[#id='portaltab-viewer']/">
<xsl:attribute name="class">selected</xsl:attribute>
</xsl:template>
But the result it's a right li portaltab-viewer with the "selected" class, but without any content inside! I obtain an empty "li" tag in the portal-globalnav O.O
What's wrong?

You need to recurse into the content of the element with xsl:apply-templates. Try:
<replace if-path="/viewer" css:content-children="li#portaltab-viewer"><xsl:attribute name="class">selected</xsl:attribute><xsl:apply-templates select="node()"/></replace>
The lack of whitespace before the xsl:attribute is necessary as I don't think I ever got around to making Diazo ignore whitespace around xsl:* elements.

i'm displaying the content of a document in an overlay using
plone/document?ajax_load=True&ajax_include_head=True as the src for an iframe.
in development mode appending &diazo.off=1 did the trick.
on the production server this sadly does not work, so i added the
ajax_load parameter as suggested in the documentation of plone.app.theming
i wrapped all my directives in a <rules if-not="$ajax_load"> element to make sure they are not applied (see code below)
now i'd need to mark the body of the iframed page with a certain class to apply different styles (eg no background color for the body in overlays)
the solution proposed for a nearly similar question does only work if you are using a theme with a body element having a class attribute to operate on.
is there a way to add a class to the content without having a theme (using )?
or do i have to supply an empty html document (index2.html) as theme and apply lots of rules to copy over css/js etc twice?
<rules if="$ajax_load">
<!-- theme href="index.html" /-->
<notheme />
<!-- only works when using a theme -->
<before theme-children="/html/body"><xsl:attribute name="class"><xsl:value-of select="/html/body/#class"/> my class</xsl:attribute></before>
<!-- thought this could to the trick but does not work at all -->
<xsl:template match="html/body">
<xsl:attribute name="class"> foo</xsl:attribute>
</xsl:template>
</rules>
<rules if-not="$ajax_load">
<theme href="index.html" />
<replace content="/html/head/title" theme="/html/head/title" />
...
Obviously without a theme to operate on, any rule referencing a theme does not work in conjunction with <notheme/>. You can however <drop> and <replace> content (I have ideas of how to implement <before> and <after> content, but its difficult to implement. Maybe in a future version of Diazo.) However you can achieve the same thing with a small amount of xslt:
<replace content="/html/body/#class">
<xsl:attribute name="class"><xsl:value-of select="."/> newclass</xsl:attribute>
</replace>
If you are using plone.app.jquerytools for your overlays, then you can pass a class parameter:
$('a.myPopover').prepOverlay({
subtype: 'iframe',
cssclass: 'my-popover'
});
In some of our project using plone.app.tiles we used a specific theme template for the overlays, that was stripped of all unecessary parts and reduced to a single wrapper div and used it for the tile edit view like so:
<theme href="minimal.html" if-path="##edit-tile" />
I am trying to use the anchor button in a RTF field of a Component, and getting unexpected behavior. Using the Chrome Browser from the design view, I highlight/select the heading (i.e. <h2>My Heading</h2>) I want to use as an anchor, and press the anchor button and enter the anchor name (i.e. my_place).
This results in the following code being displayed in my source tab:
<a name="my_place" id="myplace"/><h2>My Heading</h2>
This causes render problems when displaying the HTML in a browser due to the self closing <a/> tag.
I would have expected one of the following three HTML fragments being inserted into the HTML source:
<a name="my_place" id="myplace"><h2>My Heading</h2></a>
or
<h2><a name="my_place" id="myplace">My Heading</a></h2>
or
<a name="my_place" id="myplace"><a><h2>My Heading</h2>
Has anyone else experienced this? or know of a way to achieve what I had expected (without manually editing the HTML). Or is this a bug in the current version of the product.
Attached is my sample XSLT template:
<template match="a[(#name) and (count(node()) = 0)]">
<copy>
<apply-templates select="#*"/>
<xhtml:span xmlns:xhtml="http://www.w3.org/1999/xhtml" class="hidden"> </xhtml:span>
</copy>
</template>
This adds a bit more than strictly needed, but handles some other issues we have due to XML manipulation on the Content Delivery side.
Essentially it matches all empty a tags with a name attribute, and add something between them in order to stop them self closing. In our case we post process all of the XML with XSLT, so we have challenges with empty tags getting closed all the time. So as a dirty hack, we are now inserting a hidden span tag between empty tags to prevent the issue.
Thanks Chris, I've edited your solution to fit my requirements so wanted to share for anyone with this issue in the future.
Note: This moves the text inside the anchor and deletes the text outside. Fixes anchors that were intended to contain text only, not html. i.e
My solution fixes this tag:
<p><a name="anchor1" id="anchor1"></a>Anchor text</p>
To
<p><a name="anchor1" id="anchor1">Anchor text</a></p>
But not this:
<p><a name="anchor1" id="anchor1"></a><h1>Anchor text</h1></p>
Here's my xsl. Hopefully it will help give you a base, I'm sure you could easily update it to look for a following tag (I don't require this for my solution).
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" method="html" cdata-section-elements="script"/>
<xsl:template match="/ | node() | #*">
<xsl:copy>
<xsl:apply-templates select="node() | #*"/>
</xsl:copy>
</xsl:template>
<!-- fixes Tridion bug when using interface button to insert anchor in rich text field -->
<!-- gets all empty anchor tags with an id and takes any following text and copies it inside anchor -->
<xsl:template match="a[(#id) and (count(node()) = 0)]">
<xsl:copy>
<xsl:for-each select="#*">
<xsl:attribute name="{name(.)}">
<xsl:value-of select="."/>
</xsl:attribute>
</xsl:for-each>
<xsl:value-of select="normalize-space(following-sibling::text())"/>
</xsl:copy>
</xsl:template>
<!-- delete any text after an empty anchor (template above has already copied this text inside the anchor) -->
<xsl:template match="text()[preceding-sibling::a[(#id) and (count(node()) = 0)]]" ></xsl:template>
</xsl:stylesheet>
Here's my test XML
<?xml version ="1.0"?>
<?xml-stylesheet type="text/xsl" href="tridionhtmlfield.xsl"?>
<html>
<head></head>
<body>
<p><a id="anchorlink" name="anchorlink" title="Anchor link" href="#Anchor">Anchor link</a>Some text after</p>
<p><a name="broken-with-html-name" id="broken-with-html-id"></a><h1>Anchor - broken with html</h1></p>
<p><a name="broken-text-only-name" id="broken-text-only-id"></a>Anchor - broken text only</p>
<p><a name="broken-notext-name" id="broken-notext-id"></a></p>
<p><a name="correct-name" id="correct-id">Anchor - correctly rendered</a> Some text after</p>
</body>
</html>
After transform:
<html>
<head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"></head>
<body>
<p><a id="anchorlink" name="anchorlink" title="Anchor link" href="#Anchor">Anchor link</a>Some text after</p>
<p><a name="broken-with-html-name" id="broken-with-html-id"></a><h1>Anchor - broken with html</h1></p>
<p><a name="broken-text-only-name" id="broken-text-only-id">Anchor - broken text only</a></p>
<p><a name="broken-notext-name" id="broken-notext-id"></a></p>
<p><a name="correct-name" id="correct-id">Anchor - correctly rendered</a> Some text after</p>
</body>
</html>
Hope this helps
It looks like a bug to me Chris. I've just confirmed it on Chrome, Firefox and IE. It's completely counter-intuitive that the current text selection should be ignored. (On the plus side, once you fix it manually in the source tab, everything appears to behave perfectly.)
I suggest that you report this to Tridion, and perhaps work around it by altering your templating or filter XSLT.
It is a bug in Tridion. One work-around that I suggest (and have implemented in our particular installation) is to do the following:
Edit the FormatAreaStyles.css file (found in the Tridion CMS program files) — as well as your CSS file used by the website — to include a class like this:
.hiddenanchor {
width:1px;
height: 1px;
display: block;
text-indent:-50000px;
}
Publish out your CSS file (with the new class) so that it'll format your anchors properly.
And then in the component where you are building out the anchors, you will have to:
a. type a word or series of words in your component (where you want the target to be),
b. select that text, and apply the anchor tag to it,
c. then apply the new class you've created (.hiddenanchor) to the anchor.
In the end, your "invisible" anchor would look like this:
<a name="anchorname" id="anchorname" class="hiddenanchor">Anchor Name</a>
It's a crude work-around — fully acknowledged. But it works. You don't end up with the hyperlink/underline styling until the close of the next DOM object.
As an explanation to the CSS, the anchor technically has to be visible in the DOM for it to work and to be accessible by the anchor link. So "display: none" won't work. Alternatively to taking the text-indent approach, you could absolute or fixed position the text off the screen as well.
Here is a link to the page. The Home button is supposed to be aligned directly above the Gallery button. Can anyone help me out?
http://amfotography.com/newsite/contact.html
change your
<class id="pageoff">
</class>
to
<div id="pageoff">
</div>
Just to elaborate as well I would change all your tags to valid HTML markup. I would suggest using on any menu items you have on the left and to wrap around content.
#pageoff a {
display: block;
}
That would work in your current layout.
However, your HTML is a problem, there is no "class" element - change all to a div and it will fix itself.
The rest of your highest level menu items are wrapped in <class id="pageoff">
Change:
Home
to:
<p>
<class id="pageoff">
Home
</class>
</p>
There is also an extra <br /> above the class for Galleries you will want to remove to have it directly above.
Using Diazo, I have an id clash between the theme and the content and some JS which depends on the content id. How can I change the elements id attribute in the theme from one value to another?
The easiest way to change a value in the theme is to open it in your editor and edit the html ;) If you're after changing the id in the content to match markup in the theme then you can use a replace content rule, see: http://diazo.org/advanced.html#modifying-the-content-on-the-fly
(The replace content rule basically replaces xsl:template's in Diazo. The latter still work, but you should normally use the replace content now.)
This should work:
<replace css:theme="{theme-selector}" css:content="{content-selector}" />
<xsl:template match="{theme-selector}">
<xsl:attribute name="{attr-name}">
<xsl:value-of select="{attr-value}" />
</xsl:attribute>
</xsl:template>

I'm trying to remove the content div only for the homepage by this line (in the rules.xml)
<drop css:theme="#content"
if-content="/html/body[#class='section-front-page']" />
It doesn't work ... why? It seems ok for me :)
You can use CSS selectors, too:
<drop css:theme="#content"
css:if-content="body.section-front-page" />
This resolves to the same XPath expression, but it's a lot easier on the eye
See: http://pivotallabs.com/users/alex/blog/articles/427-xpath-css-class-matching
To use that syntax you would have to match on all the classes for the body tag
Use:
/html/body[
contains(
concat(' ',normalize-space(#class),' '),
' section-front-page '
)
]
(works for me in FireBug)
