Re: Doing math in XSLT?

I found at least one problem which is the substring-after. Not all of my
tables use col as a prefix but use just c. Not sure how that happens as these
are complex tables and I'm sure would have been created in the table
editor.Now exploring regex to just match the digits, but that looks like
analyze-string to do that. I'll have to research further to make sure there
are always digits in the name. May be safer to pull the value from the
collection definition. It looks like if there are no spans the colnum is not
added.Sent from my Verizon, Samsung Galaxy smartphone

Doing math in XSLT? Seems the problem is not in what you have described, but
somewhere else.I cannot reproduce it.When this transformation:<xsl:stylesheet

</row>

The attributes nameend="col2" namest="col1" indicate that this row spans
2 columns (end - start + 1).

I've tried this to try and get the numbers 1 and 2 from these strings,
but I get NaN errors

<xsl:variable name="start"
B  B  B  B  select="number(substring-after(@namest, 'col'))" as="xs:double"/>
<xsl:variable name="end"
B  B  B  B  select="number(substring-after(@nameend, 'col'))"
as="xs:double"/>

I've tried this in different combinations with/without the
as="xs:double" and number() and those variations throw the same error.

The table itself has this information

<table colsep="0" frame="none" id="table_post_oauthClients_endpoints"
B  B  B  B  rowsep="0">
B  B  B  B  <tgroup align="left" cols="2">
B  B  B  B  B  B  B  B  <colspec colname="col1" colnum="1" colwidth="1*"/>
B  B  B  B  B  B  B  B  <colspec colname="col2" colnum="2" colwidth="3*"/>
B  B  B  B  B  B  B  B  <thead>
B  B  B  B  B  B  B  B  B  B  B  B  <row>
B  B  B  B  B  B  B  B  B  B  B  B  B  B  B  B  <entry
colname="col1">Parameter</entry>
B  B  B  B  B  B  B  B  B  B  B  B  B  B  B  B  <entry
colname="col2">Description</entry>
B  B  B  B  B  B  B  B  B  B  B  B  </row>
B  B  B  B  B  B  B  B  </thead>

I'll try referencing the <colspec> element and using the @column value,
but that seems like it will give me the same issue.
