If string Null then add spaces
Hi All
Thanks for your help in advance
Very new to XSLT. Don't laugh at my basic skills. I would like to check to see if there is any easy and efficient way of re-writing this.
Appreciate your help in advance
I am combining all fields into Rows for each record and trying to build fixed length row at the end to output to a flat file which will be done in SAP Integration tool. The file adapter is unable to handle multiple hierarchy in SAP. So i am playing with XSLT here.
When combing the fields, if the field value is null where i would be adding spaces. One example with available. But i have to apply this for every field in the XSLT and pass the field length as a variable for easy handling.
<xsl:template match="/">

You'll have to explain what you mean by "null" because there is no such concept in the XPath data model. Possible meanings:
- the element doesn't exist
- the element exists but has no (text or element) child nodes
- the element content consists entirely of whitespace
It's also useful to say whether you are using XSLT 1.0, 2.0, or 3.0, since the solutions may well vary.

I may need to consider below two items for my requirement
- the element doesn't exist
- the element exists but has no (text or element) child nodes

You can use
Code:
<xsl:when test="foo">...</xsl:when>
to check whether a foo element exists (as a child of the context node) and
Code:
<xsl:when test="foo[not(* | text())]">
to check that a foo element exists but does not have any element or text child nodes. Unless you want to allow comment nodes and processing instruction nodes you might simply want
Code:
<xsl:when test="foo[not(node())]">
which checks that there is a foo element with no child nodes at all.

is there an easy way to add spaces other than multiple time?

In XSLT 2.0 you can do
Code:
string-join(for $i in 1 to $N return ' ', '')
In XSLT 1.0 you can do
Code:
substring($spaces, 1, $N)
where $spaces is a variable containing more spaces than you will ever need.

where does the snippet of code go into this template.
<xsl:template match="node()" mode="format">
<xsl:param name="width"/>
<xsl:value-of select="substring(concat(text(),$some_spaces ), 1, $width+1)"/>
</xsl:template>
<xsl:template match="node()" mode="format_date">
<xsl:param name="width"/>
<xsl:value-of select="substring(concat(translate(text(),'/',''),$some_spaces ), 1, $width+1)"/>

The first template takes the text content of the current node (text()), appends some spaces, and then returns the first $width characters of the result.
The second template does something very similar except that it uses translate() to remove "/" characters first.
Not sure which part of that you had difficulty understanding; if I knew where your difficulty was then I could explain that bit more carefully.
