CSS select previous sibling

[dvezina]

Hi,

My CSS looks like this:

Code: Select all

CITY + NEIGHBORHOOD[name=""] {

    display:inline;

    font-style:italic;

    content: oxy_xpath("//CITY/@name");

}

My XML looks like this:

Code: Select all

<LISTING>

    <COUNTRY geo_id="0" id="1051" name="Canada"/>

    <STATE geo_id="0" id="48999" name="North America|Canada|British Columbia"/>

    <CITY geo_id="0" id="5503" name="North America|Canada|British Columbia|Whistler"></CITY>

    <NEIGHBORHOOD geo_id="" id="0" name=""/>

</LISTING>

The expected output is:
North America|Canada|British Columbia|Whistler

Does anyone see why this doesn't work.

THANKS

Hi,

I tested the samples you provided and in my case the author mode presented just what you've expected : North America|Canada|British Columbia|Whistler. Perhaps there is a StylesFilter involved and it also changes the styles of the element? If not, what Oxygen version you are using? If you test these samples in a fresh Oxygen installation (one that has just the default frameworks) are they working as expected?

Best regards,
Alex

There is a StyleFilter and DocumentModificationFilter (setAttribute) in play.

If CITY and NEIGBORHOOD are in LISTING, they are form controls. If they are a chapter, I render them as normal text. Everything seems to work but the xpath with the attribte that doesnt work.

My StyleFilter code is:

Code: Select all

		else if (authorNode.getName().equals("CITY")) {

			// getOwnerDocument returns null when part of DocumentFrgement

			// This is what crashes [+ City] action

			AuthorNode authorDocument = authorNode.getOwnerDocument();

			if (authorDocument != null) {

				AuthorElement rootElement = authorNode.getOwnerDocument().getRootElement();

				if (rootElement.getName().equals("LISTING")) {

					EditorContent editorContent = geosBuilder.getEditorContent("city");

					styles.setProperty(Styles.KEY_MIXED_CONTENT, new StaticContent[] {editorContent});

					returnAlteredStyles = true;

				}

			}

		}	

		else if (authorNode.getName().equals("NEIGHBORHOOD")) {

			// getOwnerDocument returns null when part of DocumentFrgement

			// This is what crashes [+ Hood] action

			AuthorNode authorDocument = authorNode.getOwnerDocument();

			if (authorDocument != null) {

				AuthorElement rootElement = authorNode.getOwnerDocument().getRootElement();

				if (rootElement.getName().equals("LISTING")) {

					EditorContent editorContent = geosBuilder.getEditorContent("hood");

					styles.setProperty(Styles.KEY_MIXED_CONTENT, new StaticContent[] {editorContent});

					returnAlteredStyles = true;

				}

			}

		}	

My CSS is attempting th following: (1) If NEIGHBORBHOOD/@name is empty or does not exist, print CITY/@name, (2)Otherwise print NEIGHBORHOOD/@name.

Code: Select all

/*DOES NOT WORK/

CITY + NEIGHBORHOOD[name=""] {

    display:inline;

    font-style:italic;

    content: ", " oxy_xpath("//CITY/@name");

}



/*WORKS*/

CITY + NEIGHBORHOOD[name*="|"] {    

	display:inline;

	font-style:italic;

     content: ", " oxy_substring(attr(name), oxy_add(oxy_lastindexof(attr(name), '|'), 1, integer));

}



/*WORKS*/

CITY + NEIGHBORHOOD[name] {    

	display:inline;

	font-style:italic;

     content: ", " oxy_substring(attr(name), oxy_add(oxy_lastindexof(attr(name), '|'), 1, integer));

}

What I did notice is that if I use oxy_xpath("//CITY/text()"), I do get the text. So it appears to be the name attribute. I will try to run this down in the DocumentModificationsFilter.

Thanks for your help

Hi Deanna,

The code below, changes the content property in the styles. This is the same property on which you put the oxy_xpath() on. The StylesFilter is applied last so it will override the rule from the CSS.

Code: Select all

else if (authorNode.getName().equals("NEIGHBORHOOD")) {

  // getOwnerDocument returns null when part of DocumentFrgement

  // This is what crashes [+ Hood] action

  AuthorNode authorDocument = authorNode.getOwnerDocument();

  if (authorDocument != null) {

    AuthorElement rootElement = authorNode.getOwnerDocument().getRootElement();

    if (rootElement.getName().equals("LISTING")) {

      EditorContent editorContent = geosBuilder.getEditorContent("hood");

      styles.setProperty(Styles.KEY_MIXED_CONTENT, new StaticContent[] {editorContent});

      returnAlteredStyles = true;

    }

  }

}

You should probably add some checks in the StylesFilter to only change the content property of NEIGHBORBHOOD so that it doesn't overlap with the CSS rules. It's strange that oxy_xpath("//CITY/text()") works, because from the StylesFilter code looks like it always overrides the content of NEIGHBORBHOOD.
