document function in formspublisher presentation template

Hi,

I have a DCR, "content.xml". The DCR has a textarea whose value is an xml.

The XML has a tag called "Image".

The "Image" tag's attribute "path" has the relative path for another dcr(path starts with "templatedata/something/something/data/filename.xml").

This file has the path to the actual image file. the xpath is like "/root/element/imgpath".

Now how do I access the value contained in imgpath which is in say "Image.xml", from the xsl i have written to parse content.xml, say "content.xsl"?

Note that content and image are dcrs for different datatypes(dct).

I tried giving the image tage like this

path)//imgpath"/> and variations of this.

But in the preview i do not get the image. The html in the view source gives the image tag like this:

<img src="" />.

path"/>, but nothing was printed.

Any help is welcome. Thanks to all in advance.

Hi,

@path : Will not print anything as it is inside the xml which can not be directly accessed.

You have textarea so anything written inside will be string.

Suggestion :

1) Replace textarea with browse field.

2) Browse the DCR in this field.

3) In your xsl pass this path to your document function.

4) You will get the path.

Eg.

If your content.xml looks like this -

<root>
  <imageDCR>templatedata/something/something/data/filename.xml</imageDCR>
</root>

In your xsl, you can use like this -

<xsl:variable name = "imageScr">
  <xsl:value-of select = "document(/root/imageDCR)//imgpath"/>
</xsl:variable>

<img scr = "$imageScr"/>

Hope this will help you.

Thanks for that, but the requirement is that it has to be a textarea.

Also I have used a parser to return the value in the textarea as a proper xml.

I am able to render other items in the xml as needed. I am not able to render the image only.

The only difference between the other tags and this is that the other tags have values directly in them but the image tag refers to another DCR

Hi,

Ok then try this this -

1) Fetch the value of textarea in one varaible.

Say -

<xsl:variable name="imageDCR">
<xsl:value-of select="xpath-of-textarea"/>
</xsl:variable>

2) Use "$imageDCR/root/element/imgpath/@path" in your document function like this -

<xsl:variable name="imageDCRPath">
<xsl:value-of select="$imageDCR/Image/@path"/>
</xsl:variable>

3) Use "$imageDCRPath" in your document function like this -

<xsl:variable name="imageScr">
<xsl:value-of select="document($imageDCRPath)/root/element/imgpath"/>
</xsl:variable>

4) Use this in img tag -

<img scr = "{$imageScr}"/>

If this didn't work, please attach your content.xml, Image.xml and content.xsl
