xsl:for-each?

pietromaria.liuzzo · August 15th, 2013, 05:50 AM

Dear all,

I have now this problem:

I used xsl:analyze-string to match this regex

((.*)//)* (.*)

and I would like to pass onto xsl:matching-substring each of the eventual (.*)//.

if that possible?
I have tried with xsl:if and xsl:for-each select="regex-group(1)"

but I must be doing something wrong... or taking the problem from the wrong point

Thank you very much

Yes, you are doing something wrong.

If you show us what you are doing then perhaps we can tell you what you are doing wrong.

sorry, here is the full code.

Code:

<xsl:analyze-string select="." regex="((.*)//)* (.*)" flags="s">
                <xsl:matching-substring>
                    <xsl:if test="regex-group(1)">
<xsl:for-each select="regex-group(2)"><div>
                        <ab><lb/>
                            <xsl:variable name="brackets">
                                <xsl:call-template name="breakbrackets">
                                    <xsl:with-param name="textToBeProcessed"        select="regex-group(2)"/>
                                </xsl:call-template>
                            </xsl:variable>
                            <xsl:for-each select="$brackets">
                                <xsl:call-template name="upconversion"/>
                            </xsl:for-each>
                        </ab>
                    </div>
</xsl:for-each>
</xsl:if>
                    <div>
                        <ab><lb/>
                            <xsl:variable name="brackets">
                                <xsl:call-template name="breakbrackets">
                                    <xsl:with-param name="textToBeProcessed" select="regex-group(3)"/>
                                </xsl:call-template>
                            </xsl:variable>
                            <xsl:for-each select="$brackets">
                                <xsl:call-template name="upconversion"/>
                            </xsl:for-each>
                        </ab>
                    </div>
                </xsl:matching-substring>
                <xsl:non-matching-substring>
                    <ab>
                        <lb/><xsl:variable name="brackets">
                            <xsl:call-template name="breakbrackets">
                                <xsl:with-param name="textToBeProcessed" select="."/>
                            </xsl:call-template>
                        </xsl:variable>
                        <xsl:for-each select="$brackets">
                            <xsl:call-template name="upconversion"/>
                        </xsl:for-each>
                    </ab>
                </xsl:non-matching-substring>
            </xsl:analyze-string>
        </div>
    </xsl:template>

Thank you very much

regex-group() always returns a single string, so using it in xsl:for-each doesn't make much sense: though it's legal and won't do any harm, it suggests you're confused about the logic.

you say you want to process "each of the eventual (.*)//.", but that's surely regex-group(1) not regex-group(2).

Beyond that, I can't see immediately what's wrong - I can't see your input or your desired output or the various templates you are calling, so that's not surprising.

pietromaria.liuzzo · August 15th, 2013, 10:11 AM

I am, indeed.

is there any other function which you could suggest me to get each string?
I have asked for the regex-group(2) because I actually want the // not to be in the result.
I have texts like this

oioia daoinda // doaindsoai // dao ids nda etc.

where // is the separator and each is a test I want to process. There are cases in which there is only one, cases in which there are 20. with my code I match 1 or 2.

iIf there is one text I want it to do what is in the non matching, if it has more I want it to behave according to the matching (with the div and the ab in the div.

could I use tokenize() or matches()?

I am not immediately able to try unfortunately...

Thank you very much

Can't you simply use

Code:

<xsl:for-each select="tokenize(.., '//')"

You seem to be making this far more complicated than it is.
