I want to check the value of each bId element. If this value is the same with the preceding or following bId element in the o-ru-con element, then I will group all the different co-ru-con block (in the whole block o-ru-con) with the same value of bId in one co-ru-con as shown in the expected output file.
I tried to use this xsl file:
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:strip-space elements="*"/>
<xsl:output indent="yes"/>
<!-- -->
<xsl:template match="*">
<xsl:copy>
<xsl:copy-of select="@*"/>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:key name="k1"
match="ru-con-ite-lit[bId = preceding-sibling::ru-con-ite-lit[1]/bId]"
use="generate-id(preceding-sibling::ru-con-ite-lit[not(bId = preceding-sibling::ru-con-ite-lit[1]/bId)][1])"/>
<xsl:template match="ru-con-ite">
<xsl:copy>
<xsl:copy-of select="@*"/>
<xsl:apply-templates select="ru-con-ite-lit[not(preceding-sibling::ru-con-ite-lit[1]) or not(bId = preceding-sibling::ru-con-ite-lit[1]/bId)]"/>
</xsl:copy>
</xsl:template>
<xsl:template match="ru-con-ite-lit">
<xsl:copy>
<xsl:copy-of select="@*"/>
<!-- <xsl:apply-templates/>-->
<xsl:apply-templates select=". | key('k1', generate-id())" mode="sp"/>
</xsl:copy>
</xsl:template>
<xsl:template match="ru-con-ite-lit" mode="sp">
<xsl:copy-of select="node()[not(self::bId)]"/>
</xsl:template>
</xsl:stylesheet>
I can remove the element bId in my xml file with this xsl file, but I cann’t group the different co-ru-con block with the same value of bId in one co-ru-con block. The expected output will look like this:

Thanks
This looks like a grouping issue, and in XSLT1.0 this is a job for Muenchian Grouping. In your case you are grouping co-run-con elements by a combination of there parent o-ru-con element, and their descendant bId element. Therefore you would start by defining a key for this
Then, whenever you match a o-ru-con element, you would then match distinct co-ru-con by looking for such elements that were the first occurence of that element in the key
This would allow you to create a single co-ru-con element for the group. You would then match the child si-ru-con elements for the group like so
Here is the full XSLT
When applied to your sample XML, the following is output
